Programmable DC Bench Power Supply – 30V to 120V, 0–10A with OVP/OCP

This programmable DC bench power supply is engineered for professional users who require accurate, stable, and flexible DC output across a wide range of applications. Available in multiple voltage and current configurations, it supports constant voltage (CV) and constant current (CC) operation, making it suitable for both sensitive electronics and higher-power testing tasks.

Enhanced Over-Voltage Protection (OVP) and Over-Current Protection (OCP) functions can be enabled via dedicated front-panel buttons. When abnormal conditions such as overloads, short circuits, or incorrect settings are detected, the power supply automatically shuts down the output, triggers an audible alarm, and provides visual indication—protecting both the power supply and connected equipment.

A precision digital encoder control system replaces traditional potentiometers, allowing fast yet highly accurate voltage and current adjustment. Users can preset values without energising the output, improving safety and reducing the risk of accidental damage. A dedicated OUTPUT switch enables quick toggling of the output without disconnecting the load.

The unit also integrates USB-A and USB-C fast-charging ports for powering auxiliary devices such as development boards, phones, and tablets. An intelligent temperature-controlled cooling fan ensures quiet operation under light loads while maintaining effective heat dissipation during extended use.

Built with high-quality electronic components and comprehensive protection circuits, this bench power supply is suitable for laboratories, workshops, classrooms, and industrial test environments.
