Adjustable DC Bench Power Supply – 0–30V 0–3A Regulated CV/CC Laboratory Power

This regulated DC bench power supply is designed for stable, precise, and repeatable power delivery in professional and educational environments. With adjustable voltage and current control, it automatically switches between constant voltage (CV) and constant current (CC) modes depending on load conditions, ensuring safe operation with sensitive electronics.

The unit features coarse and fine adjustment controls, allowing accurate tuning of output parameters. A dedicated output ON/OFF switch enables voltage and current to be preset before energising the load, reducing the risk of accidental damage during setup.

A high-visibility LED display provides real-time readouts of voltage, current, and power. Built-in electronic protection systems—including over-voltage, over-current, over-temperature, overload, and short-circuit protection—ensure reliable operation and long service life.

The compact, lightweight design makes it suitable for benchtop use in labs, classrooms, workshops, and mobile service environments. A temperature-controlled cooling fan activates automatically when internal temperatures rise, providing efficient heat dissipation with low noise.
