Programmable supplies feature remote sense without wires
Campbell, CA. Versatile Power, producer of programmable laboratory bench and OEM power supplies, has introduced its BENCH XR line of 600-W programmable supplies. The company says the BENCH XR power supplies are the industry’s first to provide accurate point-of-load voltage regulation over a range of load conditions—without the use of an auxiliary remote sense circuit.
Remote sense is implemented utilizing the Versatile Power’s patent-pending digital control to instantaneously adjust the voltage at the output terminals in response to changes in output current. This technique eliminates output noise that is often introduced by conventional remote-sense wiring. In addition, by eliminating the remote sense wiring, the BENCH XR is not susceptible to failures caused by ground loops or reverse-polarity sense-wiring connections.
The BENCH XR series of 600-W programmable power supplies are packaged in a compact, 1U, ½-rack-width enclosure. Five models provide for output voltage and current ranging from 30 V to 400 V and 2.5 A to 33 A. Digital display of output current and point-of-load voltage is provided. Multiple standard I/O interfaces (Ethernet, USB 2.0, and analog) facilitate setup and operation of test protocols. The BENCH XR Series supports SCPI.
“The package size of the BENCH XR is a real advantage in many test applications,” said Jerry Price, Versatile Power CEO. “The ability to perform remote sense without any added wiring both simplifies setup and improves power supply performance and reliability.” Price is $1,295.
