Power Supply Voltage Drops: The Basics

If you’re noticing decreased efficiency in your electronic systems and equipment, they may be experiencing what’s known as voltage drop. While power supply voltage drops can be damaging, understanding the basics and how to combat them can help you prevent future harm and protect your equipment. Keep reading to make sure you understand what a voltage drop is, common causes, and how to reduce the risk of voltage drops.

What is a Voltage Drop?

A supply voltage drop describes how the energy of a power supply decreases as the electrical current flows through passive elements in an electrical circuit. The potential for voltage drop increases with the length of the circuit. The further the electricity travels from the power supply, the higher the risk of voltage drop, resulting in weaker currents and decreased power.

Excessive voltage drop can be damaging and may lead to disruptions, inefficient electrical systems, and even mechanical harm. These issues can negatively impact your electrical equipment, potentially resulting in higher operating costs and decreased productivity. Understanding some of the most common sources of voltage drops can help you better prepare for and prevent damage to your electrical systems.

Common Causes of Supply Voltage Drop

  • Length of the power cable
  • Cable gauge size
  • Using AC power over DC power
  • Amount of current at the power supply
  • Power line resistance

How to Measure Voltage Drop

While small amounts of voltage drop are expected―especially for lengthy electrical circuits―monitoring for excessive voltage drop can help protect your equipment and prevent harm.

Ohm’s law describes a formula to calculate the proportional relationship between voltage, current, and resistance. The formula to calculate voltage drop is:

V = I x R

Where V represents voltage, I represents current, and R represents resistance. For further assistance in calculating voltage drop, contact a team member at Quail Electronics, Inc.

Minimize Voltage Drop in Your Power Supply

You can use various techniques to compensate for the effect of voltage drop on long circuits or where voltage levels must be accurately maintained.

  • Appropriate Wire Size: The most important factor in avoiding excessive voltage drop is selecting the correct wire size. Choose a wire gauge appropriate for the distance and current you require to best reduce resistance in your system.
  • Increase Conductor Size: One of the simplest ways to reduce voltage drop is to increase the diameter of the conductor between the source and the load, lowering the overall resistance.
  • Routine Inspection: Regularly examining your power cables and electrical systems will help you quickly identify any significant voltage drop. Make any necessary repairs as fast as possible to avoid lasting damage or costly maintenance.
  • Specialized Power Supply Design: Custom-made power cords and connectors can help you easily balance power loads and regulate voltage levels for improved performance.
  • High Voltage Power Cables: Using high-voltage power cords increases the amount of voltage flowing through a circuit and minimizes the amount of current. Higher voltage levels result in decreased voltage drop.

Different Wire Termination Styles for Power Cords

Wire termination refers to the end style of a power cord. The way a cable is terminated affects its applications and determines how it can be used.

In this blog, we talk about the different ways to terminate a power cord, various wire termination methods, and types of electrical terminals for creating new cable connections.

Types of Power Cable Ends

The end of a power cable determines the available wire termination methods for that specific application. The most common cord end styles for power cables are:

  • Standard Ends
  • Stripped Ends
  • Custom Ends

For standard power cords, both ends can be plugged in or unplugged, and the cord is ready to use. All internal wires are hidden, meaning wire termination is contained in the plug or connector. However, for stripped and custom power cable ends, there are different ways to terminate a cord’s exposed wires.

Wire Termination Methods for Stripped End Power Cords

Stripped end power cords feature exposed wiring, where the insulation has been removed or “stripped” away from one end of the power cord. Also referred to as removed outer jacket cords or ROJ cords, the wire termination methods for these cords are permanent and result in reliable results.

Crimped Wire Termination

Crimped wire termination is named for the crimping tool required. A contact or terminal is “crimped” to the stripped wire, forming a permanent attachment. Crimp termination is the most common type of wire termination and forms a mechanically strong, reliable connection between the power cord and the attached terminal.

Soldering Wire Termination

Soldering wire termination is often used for direct hard-wiring applications. The stripped wires are treated with Flux and the desired contact or terminal is soldered directly to the exposed wires. Soldered wire termination is often used for simple applications or when a wire is too small for crimping tools.

Terminals for Stripped & Custom Cable Termination

Stripped and custom-end power cables use electrical terminals to create new ends for connections. Available in insulated styles, terminals come in a range of connection options:

  • Ring Terminals: Used to ground a wire in a device.
  • Locking Ring Terminals: Offer a more secure connection for grounding wires.
  • Fork/Spade Terminals: Allows for fast wire connections.
  • Quick Disconnect Terminals: Used when wires require fast disconnection.
  • Flag Terminals: A left-angle version of quick disconnect terminals.

When selecting a terminal, ensure the sizing matches your wire gauge.

Mounting Snap-On Inlets vs. Screw-On Inlets

If you want a complete electrical circuit, you need an inlet. Inlets, or appliance couplers, are the input power connection that helps guide the flow of electricity from a source to a plugged-in device. In other words, you can’t connect power sources without them. However, the type of inlet you need may vary based on application and use.

There are two different ways to mount a power connector. In this blog, we compare snap-on inlets and screw-on inlets so you can choose the best mounting type for your needs. Keep reading to learn more, and contact us with any questions.

Electrical Inlets: The Basics

Before differentiating between styles of inlets, there are a few pieces of shared information that hold true for all electrical inlets:

  • Male: Inlets are used with connectors, often the outlet end of power cords. Most inlets are male or have prongs for female connectors to join with them.
  • Identification: Every inlet type is labeled with a “C” followed by a number. The inlet’s number is always one more than its corresponding connector. For example, C19 connectors match with a C20 inlets.
  • Power Supply: Inlets serve as a stable access point for receiving and transferring power to plugged-in devices and appliances.

Snap-On Inlets

One mounting method for power connecters is using snap-on inlets. These inlets have plastic grooves or clips for secure mounts, providing fast and easy installation. Soldered ends or quick disconnect terminals connect from metal tabs at the back of the inlet to your equipment’s live wire. Additionally, snap-on inlets can be quickly removed and reattached if necessary. While the grooves can reliably hold the inlet in place for many standard applications, snap-on inlets may not be secure when exposed to high-stress environments.

Common Mountings for Snap-On Inlets

Snap-on inlets can be used for low-impact projects, including:

  • Data servers and server rooms
  • Home appliances
  • Indoor lighting systems
  • Office equipment
  • And more!

Screw-On Inlets

Screw-on inlets are another popular mounting style for power connectors. These inlets have built-in holes on the sides, where screws can be inserted and tightened for added security. The screws create permanent holds, reducing the risk of accidental disconnections and reinforcing reliable attachments. Screw-on inlets offer durability and stability to power connections in high-stress environments.

Common Mountings for Snap-On Inlets

Screw-on inlets are ideal for various heavy-duty applications, such as:

  • Power distribution units
  • RVs, boats, and mobile vehicles
  • Outdoor lighting systems
  • Industrial machinery
  • And more!

Power Strips vs. Surge Protectors: A Comparison

When establishing electrical connections for multiple devices, one of the most important considerations is choosing between power strips and surge protectors. While there are many similarities between them—the ability to power several devices at once, the overall design and appearance, and the primary function—there are several distinct differences to understand before making your selection.

Keep reading to learn the different characteristics of universal power strips and surge protectors, as well as how to determine which is best for your needs.

What’s the Difference?

Power Strips

A power strip is an electrical unit with multiple electrical sockets enclosed in an electrically shielded case. These units are connected to a wall socket by a single power cord, increasing the number of outlets available from one socket. There are many different types of power strips, including hospital-grade, international, and North American. While these units are designed for specific applications, they do not offer any additional protection from electrical issues like voltage spikes. Power strips are generally cost-effective and excellent for standard applications.

Surge Protectors

In addition to performing the same basic functions as a universal power strip, a surge protector offers extra protection against electrical surges. Internal electrical components redirect sudden voltage spikes or excess energy to protect your equipment. Often, a surge protector will feature an illuminated indicator light, demonstrating that its protection is active. Surge protectors are typically more costly than power strips, but their added protection ensures more safety.

Choosing Between Surge Protectors and Universal Power Strips

Several factors should be considered before selecting a power strip or surge protector. Perhaps the most important consideration is the type of device being powered. A power strip is suitable for simple or low-risk applications such as lamps, chargers, and small appliances. A surge protector, however, is the better option for sensitive devices demanding protection, including desktop computers, TVs, and large appliances.

Additional considerations include:

  • Environment or area of use: A universal power strip is sufficient for stable environments, while a surge protector is ideal for areas prone to electrical instability.
  • Safety: Both power strips and surge protectors have maximum capacities for devices and voltages. Be sure not to overload your extension strips.
  • Budget and long-term goals: While universal power strips are less expensive than surge protectors, the long-term benefits of voltage protection can save you from costly repairs in the future.

The key difference between power strips and surge protectors is that power strips only provide extra outlets, while surge protectors protect those additional outlets and your devices.

Power Cable Strain Relief

When using power cords, safety is the most important factor. In fact, many cables have built-in safety measures as extra precautions: ground pins, Auto-Lock® mechanisms, and surge protection, for starters. These components help manage the flow of electricity within the cord… but what about the cable itself? What protects the power cord from stress and damage?

Cable strain relief.

But how? What is it? How does it work? Why does it matter? We answer these questions and more below. Keep reading to learn more about cable strain relief!

Strain Relief: What Is It?

Strain relief describes the component at the base of a cable, just before the connector. This part of the cable often experiences the highest levels of stress, whether from pushing, pulling, bending, flexing, or twisting. Over time, continuous strain may cause the cord to deteriorate or break, leading to exposed wires and dangerous handling. That’s where cable strain relief comes in.

The strain relief acts as a hard shell, protecting the vulnerable portion of the cord from excessive stress. Different types of strain relief can be used depending on the style of cord and its application. However, all cable strain reliefs serve the same purpose: to protect power cords from damage.

What Are the Types of Strain Relief?

Standard Strain Relief

Standard cable strain relief components are pre-installed on the cord and are molded to the jacket and part of the plug. This style of strain relief is designed to avoid any damage to the conductors and prevent the separation of the plug from the cord.

Cable Glands

Cable glands, also known as cord grips or cable connectors, are independent fittings that must be manually installed over the connector and the cable joint. These fittings serve as sealing devices, ensuring a secure and effective enclosure where the cable meets the connector.

There are different styles of cable glands, including 90° angled snap elbows, which can be used for specific applications. These designs help minimize wire strain and prevent rubbing against sharp edges when the cord passes through the equipment panel.

Where Are Cable Glands Used?

While nearly all power cords are equipped with standard cable strain relief, cable grips are separate mechanical components that must be manually added. Cord grips are available in a wide range of materials, including:

  • Stainless steel
  • Nylon
  • Silicone
  • Nickel-plated brass
  • PVC
  • Nickel-plated aluminum

The right material for your cable gland will depend on your application. For example, stainless steel and nylon are beneficial for environments with liquid or freezing temperatures, while cords exposed to chemicals or high temperatures would benefit from PVC or nickel-plated aluminum cable glands. In these cases, not only does the cable strain relief protect the cord against damage from bending or pulling, but also against harsh operating spaces.

Electric Vehicle Part 1

EV plug 1

Electric vehicles have become a way of life. To prove that is true is the new Corporate Average Fuel Economy (CAFE) standard put into place by the Obama Administration. By 2025, every new vehicle sold in the United States will need to reach at least 54.5 mpg. In order to operate, the plug-in hybrid EVs that function on batteries need to be charged occasionally. No more trips to the over-populated, busy gas stations. You can fill up right at home overnight or at work during the day. The car simply plugs in while it is immobile for a given period of time. It can also charge while being driven – once the car is coming to a stop and the brakes are applied, kinetic energy is transformed into chemical energy in the battery.
