With both coarse and fine adjustments, users can set precise values quickly. The auto CV/CC behavior is designed to protect sensitive loads by switching modes at defined crossover points. This model suits educational labs, hobbyists, and professional desks where a reliable power source is essential for testing and development.
NICE-POWER 300V 1A Programmable DC Power Supply
This NICE-POWER model emphasizes programmability with RS232/USB connectivity and Windows software for automated control. It supports precise voltage and current adjustments, multiple memory values, and data export for graphs and tables. An encoder knob provides fine manual control, while an output switch helps protect the load when changing settings. This combination makes it suitable for test benches that require repeatable, scripted power profiles and virtualization of experiments.
The unit emphasizes safety and reliability, featuring a selection of data storage and a lock function to prevent accidental changes. While software access is Windows-only, it enables scripting, logging, and reproducible power-supply scenarios in teaching labs and engineering workstations.
Jesverty SPS-V SPS-V: 0-32V, 0-10A Power Supply with USB-C
The SPS-V model advances from basic panels by introducing encoder coarse and fine adjustments, allowing precise voltage and current selection with a 0.01V/0.001A resolution. USB-A and USB-C ports provide up to 20W for fast charging of mobile devices and microcontroller boards, which is helpful for makerspaces running Arduino or Raspberry Pi projects while the bench power supply remains dedicated to lab testing. An on/off output switch makes testing safer and more convenient.
Designed for efficiency, collectors and hobbyists benefit from smoother control during long experiments and prototyping sessions. The added protection and compact form factor suit small labs, classrooms, and desk setups that require flexible power delivery without clutter.
ITECH IT6721: 60V, 8A, 180W Digital DC Power Supply
The IT6721 combines digital control with a robust 0-60V/0-8A output and a 180W rating. It offers precise 0.01V and 0.001A resolution, along with automatic CC/CV transitions to support smooth operation during load variations. Built-in protection includes OCP/OVP/OTP, contributing to safe testing environments. Its compact size makes it convenient for dense lab benches or classrooms where space is at a premium.
With memory functionality, users can save common configurations for quick recall, reducing setup time during repetitive experiments. This model is well-suited for electronics labs, educational facilities, and engineering studios that require repeatable, configurable power delivery with solid protective features.
NICE-POWER Dual 30V 10A DC Power Supply
This dual-output unit offers two 30V/10A channels, with the ability to configure series or parallel connections for higher voltage or current as needed. The product includes an output switch, a robust display, and CE/FCC certification. The design emphasizes utility for simultaneous testing of multiple circuits, making it a versatile choice for repair shops, universities, and professional makerspaces where parallel experiments are common.
Users benefit from the ability to manage two independent outputs without manual wiring between devices. Built-in protections guard against overload and short circuits, contributing to safer operation during development or educational demonstrations.

Buying Guide
Key purchase considerations for lab bench power supplies include voltage and current range, accuracy, and resolution. Look for 0.01V and 0.001A readouts to ensure fine control for delicate electronics. Automatic CV/CC switching helps protect loads during variable testing, while protections such as OVP, OCP, and OTP prevent damage from faults or misconfigurations.
Encoder knobs offer faster, precise adjustments compared with traditional pots, and dual channels or series/parallel configurations enable flexible experiments. USB or USB-C charging ports add convenience for powering microcontrollers or peripherals without drawing from the main test circuit. Memory storage is valuable for repetitive setups in classroom or lab settings, reducing setup time between experiments.
When deciding between models, consider software compatibility if you plan to automate tests. Windows-only control software can be limiting in mixed-OS environments. For basic desk use, a single-output supply with a strong CV/CC transition and a clear display may suffice. For more complex work, a dual-output, high-current configuration with robust protection and series/parallel options can unlock more testing scenarios.
Finally, ensure safety features align with your lab environment. Check that the device has proper isolation, a clearly labeled output, and protection against short circuits and overheating. This helps maintain reliable operation over extended testing sessions and reduces the risk of damage to sensitive devices or power supplies themselves.
