Description
Overview
The GW Instek PSW 250-4.5 is a single-output, multi-range programmable switching DC power supply from the PSW-Series family. With rated output of 250V and 4.5A (360W), it provides flexible voltage and current combinations within its power envelope. The unit is particularly suited for battery and LED testing applications, featuring CV/CC priority mode to protect sensitive devices from inrush currents and damage.
The supply supports both series operation (up to 2 units for higher voltage) and parallel operation (up to 3 units for higher current), enabling flexible configuration for various test requirements. Standard interfaces include LAN, USB Host/Device, and analog control, with optional GPIB-USB and RS232-USB connectivity for remote control and monitoring.
