GW Instek PSW 250-13.5 Programmable Switching DC Power Supply

Overview

The GW Instek PSW 250-13.5 is a single-output, multi-range programmable switching DC power supply from the PSW-Series, designed for demanding test and measurement applications. With a maximum output of 250V, 13.5A, and 1080W power capacity, it provides flexible voltage and current combinations within its rated power range. The unit features CV/CC priority selection specifically suited for battery and LED testing applications.

The supply supports series operation (up to 2 units) and parallel operation (up to 3 units), enabling users to achieve higher voltage or current outputs for complex testing scenarios. Its high efficiency and power density, combined with a 1/2 rack-mount form factor, make it suitable for both laboratory and production environments.
