GW power supply 80V/13.5A 360W- programmable

Product Overview

The PSW 80-13.5 is a single-output, multi-range, programmable switching DC power supply from GW-INSTEK's PSW series. The product provides an output range of 0–80 V and 0–13.5 A with a maximum power of 360 W. The unit offers a choice between CV/CC priority and adjustable slew rate to control voltage and current transitions.

What it does

The PSW 80-13.5 regulates DC output in both constant voltage and constant current modes according to user-selected priority. Adjustable slew rate allows for setting specific rise and fall times for voltage or current, which reduces inrush/surge during power-on and provides controlled transitions during test sequences. The unit also includes selectable OVP and OCP with standard levels specified in the manufacturer's documentation, as well as an analog control/monitor connection for external operation and monitoring.

Interfaces and Connectivity

• Standard LAN and USB (host/device) for remote control and data logging.
• Analog 26-pin control/monitor connector for external voltage/current control and on/off control.
• Option for series and parallel connection: up to 2 units in series and up to 3 units in parallel for increased voltage and current capacity, respectively (specified in manufacturer material).

Typical Applications

Use cases explicitly mentioned in the manufacturer's documentation include:

• Production testing of lighting devices and evaluation of LED I-V characteristics, where control of inrush and crossover between CV/C.C is relevant.
• Testing of large capacitors or other current-intensive loads, where a controlled rise time reduces peak currents at power-on.
• Testing of DC power modules, batteries, and components within the PSW series' specified application range.
