Xantrex Technology has added an Ethernet interface to its popular XFR 1.2 and 2.8kW line of programmable DC-output power supplies. The Ethernet/RS232 interface is an internally installed microprocessor-controlled option card that enables engineers to remotely control power supplies through an existing IP network or via a direct connection to a PC. With the option card installed, the XFR can communicate directly with LANs, WANs, Wi-Fi and Internet networks, making it ideal for automated test equipment and other applications where engineers require remote control and monitoring.

"XFR power supplies are easy to use and designed to provide engineers with high power density and industry-leading reliability", said Bob Collins, Sales Manager for Europe.

"The RS232 interface provides Ethernet capability that enables engineers to control systems no matter where they are located".

The Ethernet interface card features an auto-sensing 10/100Base-T network interface with an extensive command set for fast programming and read back.

This enables users to remotely control the XFR from anywhere on a network using available hubs, routers, switches and gateways.

The Ethernet/RS-232 interface functionality includes: programmable soft limits for voltage and current; programmable overvoltage protection and reset; user-programmable isolated fault, polarity, isolation and auxiliary user-defined output signals; LED status signals; and foldback in CV or CC mode with reset.

The Xantrex XFR Series use "soft switching" to eliminate noisy switching transients that generate wasted heat, and stress the power transistors to maximise efficiency and MTBF.
