Leader LPS152A

The Leader LPS152A is a triple-output DC tracking power supply delivering 30 W total output power for electronic testing, development, and repair work. It provides three independent voltage sources—0–6 V at 5 A, 0–25 V at 1 A, and 0 to −25 V at 1 A—with exceptional voltage regulation of ≤0.01% + 3 mV and current regulation of ≤0.2% + 3 mA. Ripple and noise remain below 1 mVrms (less than 3 mV p-p), ensuring clean power for sensitive circuits. The dual positive and negative 25 V outputs support voltage tracking mode for symmetric supply applications. Each output features independent adjustable current limiting and automatic overload recovery with short-circuit protection. Twin analog meters display voltage and current in real time, while accessible calibration terminals allow zeroing and adjustment of meter scales to manufacturer specifications. Input accepts 110 V or 220 V switchable at 50/60 Hz. The compact 180 mm × 90 mm × 220 mm footprint and 2 kg weight make it suitable for bench and field deployment. Outputs can be combined to safely produce up to 50 V, extending versatility for development and troubleshooting across automotive, communications, and industrial electronics applications.
