Mini Adjustable DC Bench Power Supply – 0–30V 0–5A, Encoder Control, CV/CC

This mini adjustable DC bench power supply delivers stable, accurate DC output in a compact, lightweight form factor. Designed for professional and educational use, it supports precise voltage and current setting via digital encoder knobs, allowing users to set values by digit for repeatable, efficient configuration—without the drift associated with traditional potentiometers.

The unit automatically transitions between constant voltage (CV) and constant current (CC) modes based on load conditions, ensuring safe operation during testing, charging, and diagnostics. A bright 4-digit backlit LED display provides clear real-time readouts of voltage and current, even in low-light environments.

Engineered for reliability, the power supply includes multiple electronic protections (over-voltage, over-current, over-power, over-temperature, and short-circuit). An active cooling system maintains thermal stability during extended operation while keeping noise low.

With its small footprint and light weight, this unit is well suited to crowded benches, classrooms, mobile service kits, and field work—without compromising performance.
