GW Instek PSW-1080L222 DC Power Supply

Overview

The GW Instek PSW-1080L222 is a triple-channel programmable switching DC power supply delivering up to 1080W of output power. The PSW-Multi Series features multiple voltage module options and is designed for applications requiring precise control of device power and protection against inrush currents, particularly in LED testing and battery characterization.

The supply incorporates CV/CC (constant voltage/constant current) priority mode selection, allowing operation to begin in constant current mode during power-on to prevent current spikes that could damage sensitive loads. An adjustable slew rate feature enables controlled transitions in voltage and current, further protecting devices during power-on and power-off cycles.
