High-Precision Adjustable DC Bench Power Supply with 4-Digit Display (Up to 300

This adjustable DC bench power supply offers a versatile and accurate DC power source for a wide range of applications, including electronic testing, bench diagnostics, battery charging, and product evaluation. Featuring coarse and fine adjustment controls and a high-resolution display, it enables precise setting and monitoring of voltage and current.

A compact, lightweight design makes this unit suitable for both fixed bench use and portable deployment. Built-in protective features—including over-current, over-voltage, and short-circuit protection—ensure safe operation, while automatic switching between constant-voltage and constant-current modes provides reliable performance under varying loads.

With low ripple and efficient cooling, this power supply supports stable output for sensitive electronics and power-dependent devices. Its simple operation and functional design make it suitable for workshops, laboratories, production lines, and technical training.
