Bench Power Supply — 30V 10A Variable DC with Digital Display

A regulated variable DC bench power supply is one of the last pieces of test equipment people buy and the first one they wish they'd bought sooner. Set voltage precisely, limit current to prevent damage during bringup of new circuits, and watch the live readings confirm what your design is actually drawing rather than what you calculated. The 30V/10A envelope covers virtually every prototyping scenario: microcontroller circuits, motor drivers, LED arrays, battery chargers, and RF transmitter testing.

The dual-digit LED display shows voltage and current simultaneously. Independent voltage and current knobs with coarse/fine adjustment allow precise setting without overshooting. CC (constant current) mode automatically activates when load exceeds the set current limit — protecting your circuit, not blowing it up.
