DC Power Supply
Matching the DC Power Supplies to the Application
DC power supplies are used for a wide range of applications from training the next generation of electrical engineers to developing breakthrough ultra-low power, wearable products. Whether you need a programmable DC power supply that provides power sourcing or one that pushes the limits of performance by delivering thousands of volts, choosing the appropriate variable bench power supply is critical to obtaining successful test results in teaching, research, design, and manufacturing.
How to Choose the Best DC Power Supply
The most common selection criteria are:
- Number of output channels (single or multi output)
- Output voltage, current, and power
- Setting resolution and accuracy
- Ripple and noise
- Features and programmability
- Advanced features like current measurement with nanoamp resolution, sequencing, analog inputs, digital I/O, and programming features

Frequently Asked Questions (FAQ)
Can a DC power supply be used for both prototyping and production?
Yes, many DC power supplies are versatile enough to serve both prototyping and production needs. Programmable units are particularly beneficial in production environments where different test scenarios may be required.
How does a DC power supply work?
A DC power supply works by providing a regulated direct current to power a component, module, or device. Most DC power supplies have two modes of operation. In Constant Voltage (CV) mode, the power supply controls the output voltage based on the user settings. In Constant Current (CC) mode, the power supply regulates the current.
What is a programmable DC power supply?
A Programmable DC Power Supply is a device that provides a stable and adjustable DC voltage and current output. Unlike traditional power supplies, programmable ones allow users to set and control the output parameters digitally.
Why would I need a programmable DC power supply?
These power supplies are essential in various applications, such as electronics testing, product development, research, and manufacturing. Their programmability allows for precise control in testing scenarios.
What is the purpose of using a DC power supply?
A programmable DC power supply is used by engineers to test a component, circuit or electronic device, such as IoT devices, medical products, mobile phones, and remote industrial sensors. The DC power supply allows engineers to set and supply specific voltages to power the device to confirm it’s working as intended.
