GW Instek PSW 30-72 DC Power Supply

Overview

The GW Instek PSW 30-72 is a single-output programmable switching DC power supply delivering up to 720W at 30V/72A. The PSW-Series features constant power output with multi-range voltage and current combinations, enabling flexible configuration within the rated power. This model can be connected in series (up to 2 units) or parallel (up to 3 units) for expanded voltage or current capabilities across diverse applications.

Designed for battery and LED industry applications, the PSW-Series includes CV/CC priority mode selection to protect devices under test from inrush current damage. Adjustable slew rate control enables smooth, controlled voltage and current transitions during power-on and power-off sequences, reducing surge currents that could damage sensitive components.
