10 Best Bench Power Supply 2025 in the United States

The Jesverty DC Power Supply is designed for those needing a reliable and adjustable power source, especially in lab environments or for hobby projects. With an output voltage range of 0-30V and a current range of 0-10A, it meets the basic requirements for many applications. One of its standout features is the 4-digit LED display, providing precise readings for voltage, current, and power, which is great for monitoring performance in real-time.

The unit's ability to automatically switch between constant voltage (C.V.) and constant current (C.C.) modes based on load changes adds to its versatility, making it suitable for various testing scenarios. Its compact size and lightweight nature allow for easy portability and space-saving on your workbench.

Safety is a major strength as well; it offers multiple protection features, including short-circuit protection and overload protection, which enhances reliability and extends the product's lifespan. Additionally, the inclusion of a 5V/2A USB port is a nice touch for charging smaller devices.

There are some considerations to keep in mind. While the provided test leads are a bonus, they might not be sufficient for high current applications, so users may need to invest in higher-rated leads for demanding projects. The product's relatively simple interface may not provide advanced features found in higher-end models, which might limit its use for experienced users seeking detailed control.

The NANKADF 30V 10A bench power supply is a versatile tool suitable for various electronic testing and repair tasks. It features a high-precision encoder adjustment knob, allowing you to set voltage and current accurately and easily. The output enable/disable button is a thoughtful inclusion, preventing potential damage to connected devices by ensuring you can quickly stop the output if necessary. Safety is further enhanced with an overcurrent protection feature that stops output and alerts you in case of a short circuit, safeguarding both the power supply and your devices.

The 4-digit LED display is clear and precise, showing real-time voltage and current readings down to 0.01V and 0.001A, respectively. It also includes a USB fast-charging port, making it convenient for charging other devices during use. Compact and lightweight, this power supply is easy to carry and saves space on your workbench.

However, it may fall short for users needing more than one output or higher current and voltage ranges. Additionally, while the display is accurate, some might prefer a more advanced graphical interface. This bench power supply is well-regarded for its reliability and functionality.

The Rigol DP932E Programmable Linear DC Power Supply is a versatile tool ideally suited for laboratory and electronic testing applications. With three independent channels (30V/3A, 30V/3A, 6V/3A) and a total power output of 198W, it offers a flexible range of output voltages and currents. The internal series/parallel connection for channels 1 and 2 enhances its versatility.

The unit demonstrates excellent programming and readback accuracy, ensuring precise power delivery, which is critical for sensitive electronic testing. Its transient response time of less than 50 μs and low output ripple and noise (<350 μVrms/2 mVpp) further enhance its performance by providing stable and clean power output.

The 4.3-inch LCD color touch screen, coupled with software control and various interfaces (USB, LAN, Digital I/O), adds convenience and ease of use, allowing for efficient control and monitoring of the power supply. This bench power supply also supports advanced features like a command processing time of less than 10 ms and the ability to store up to 512 arbitrary points with dwell times as short as 100 ms.

Its weight (20.1 pounds) and dimensions (9.41 x 16.5 x 6.18 inches) may make it less portable compared to smaller units. Additionally, the price point might be higher compared to other similar power supplies in the market. Despite these drawbacks, the Rigol DP932E stands out for its robust performance, precision, and advanced features, making it a solid choice for professionals in need of a reliable bench power supply.
