Compact Bench Power Supplies Offer Remote-Control Programmability

The Sorensen XEL-P series of linear regulated bench-top power supplies offer all of the manual control features of the XEL series but adds comprehensive remote-control programmability. With power up to 90 W, the ultra-compact, 1/4-rack, 3U-sized programmable power supply is ideal for rack mounted applications, while its user friendly manual controls are well suited for bench-top applications. RS-232, USB, and LAN (Ethernet) interfaces are provided as standard, with an additional GPIB interface available as an option. Each of these digital-bus interfaces provides full control of voltage, current, and output on/off, plus read-back of voltage, current, and status. The interfaces are at ground potential and are opto-isolated from the output terminals. Up to four single output units can be mounted side by side in a standard rack width. Any combination of single and dual units can be integrated with the optional rack-mount kit. All XEL supplies also come with the Output Enable feature that allows preview of the voltage and current settings before turning on the output. While a simple feature, it protects against device damage by allowing the user to verify the settings before applying them to the device being tested. Despite its small size and linear regulation, the XEL series generates little heat through the use of an advanced phase-controlled pre-regulator. In addition, internal heat-sinks use low-noise fan assisted convection cooling to remove heat. AMETEK PROGRAMMABLE POWER, San Diego, CA. (800) 733-5427.
