Description

This unit is one of the 665x series of 500 Watt, single output, series pass regulated power supplies, with an internal GPIB interface and SCPI programming. These models provide many talker/listener functions including remote programming of voltage and current with feedback of actual measured output values. Sixteen supplies can be connected to one GPIB interface via a serial link connection.
