Compact DC Bench Power Supply – 0–30V 0–3A with OVP/OCP, USB Fast Charging

This compact DC bench power supply is engineered for precision testing and development tasks across electronics R&D, embedded systems, and educational laboratories. With stable single-output DC regulation, it is well suited for PCB debugging, microcontroller development, sensor testing, semiconductor device testing, and general electronic maintenance.

The unit incorporates advanced protection systems, including over-voltage protection (OVP) and over-current protection (OCP) with audible alarms. When abnormal conditions such as short circuits or overloads are detected, the output is automatically disabled to protect connected devices.

A high-resolution digital display provides clear voltage and current readings, allowing accurate configuration before enabling output. The output switch control allows voltage and current to be preset without energising the terminals, improving safety and efficiency during setup.

Designed for portability, the power supply features a compact vertical form factor, front-mounted power switch, and shock-absorbing feet for stable bench operation. Integrated USB-A and USB-C fast-charging outputs allow convenient powering of auxiliary devices such as development boards, phones, and tablets.

An intelligent temperature-controlled cooling fan activates automatically when internal temperature rises, ensuring low noise during normal operation while maintaining long-term reliability.
