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 DP832A Programmable Linear DC Power Supply offers a versatile and powerful solution for various bench power supply needs. It features three channels with a maximum output range of 30V/3A for two channels and 5V/3A for the third, providing a total power of 195W. This range makes it suitable for a wide range of applications, from hobbyist projects to professional lab work. One of its strengths is the low output ripple and noise, ensuring stable and clean power delivery, important for sensitive electronics and testing environments.

The transient response time of under 50 μs is impressive, ensuring quick adjustments and stability during load changes. Additionally, the device includes standard over-voltage, over-current, and over-temperature protection, which enhances its safety and reliability. The 3.5-inch TFT display is clear and informative, aiding in easy monitoring and adjustments. The built-in voltage, current, and power measurements along with waveform display further add to its utility.

The multiple interfaces (USB, LAN, RS232) enhance its connectivity and control options, making it a flexible tool in both standalone and integrated setups. However, the weight of 9.15 kilograms might make it less portable, and its range of advanced functions may come with a learning curve for beginners. For those who need a reliable, feature-rich power supply with multiple outputs and robust performance, the Rigol DP832A is a solid choice. Its advanced functions and somewhat heavy design are factors to consider based on your specific needs and workspace setup.
