Programmable Single-Output Switching DC Power Supply
Product Overview
The PSW 160-14.4 from GW-INSTEK is a single-output, multi-range programmable switching DC power supply. The unit provides an adjustable voltage range up to 160 V and current up to 14.4 A, with a maximum output power of 720 W. The power supply supports both constant voltage (CV) and constant current (CC) with selectable priority and features adjustable slew rate for voltage and current transitions.
Functionality and Control
The PSW 160-14.4 offers local operation via the front panel and numerical display, as well as digital and analog interfaces for remote control and monitoring. Standard interfaces include USB and LAN, as well as an analog control/monitoring connection. GPIB-USB and RS-232-USB are mentioned as options in the manufacturer's documentation. The unit has remote sense with compensation of 0.6 V per lead.
Safety and Protection
The power supply has built-in protection features, including adjustable overload and overvoltage protection. For the PSW 160-14.4, OVP is adjustable in the range of 16–176 V, and OCP in the range of 1.44–15.84 A. In case of overtemperature or low AC input, the output will be shut off according to manufacturer's specifications.
