The JY3005D is an adjustable DC power supply delivering 0-30V and 0-5A with digital control and readout. This bench power supply features dual LED displays for voltage and current, with fine and coarse adjustment knobs for precise control. The output is short-circuit protected and includes over-voltage protection that activates in milliseconds. The unit automatically switches between constant voltage (CV) and constant current (CC) modes based on the load – in CV mode, the supply maintains set voltage while current varies; in CC mode, it limits current to the set value while voltage varies. This is critical for testing phone motherboards where you need to limit current to avoid damage. The JY3005D is a reliable, no-frills power supply perfect for phone repair shops, electronics labs, and educational settings. The compact design (only 200mm wide) fits easily on any workbench. The cooling fan is efficient and quiet during normal operation.
