The Agilent HP 6654A is a 500 Watt, single output, series pass regulated power supply, with an internal GPIB interface and SCPI programming. The 6654A provides fast, low-noise outputs; analog control of output voltage and current; and fan-speed control to minimize acoustic noise.

The 6654A, 500W linear-regulated DC power supply is designed to maximize the throughput of DUTs through the manufacturing test process with fast up and down programming time.

Programming of the dc output and the protection features can be done either from the front panel or using industry standard SCPI commands, via the GPIB. Using the serial link, up to 16 power supplies can be connected through one GPIB address. Test system integration can be further simplified be using the VXIPlug&Play drivers. The output voltage and current can also be controlled with analog signals. This is helpful for certain types of noisy environments, and also immediate reactions to process changes.

Lab bench use is enhanced by the fan speed control, which helps to minimize the acoustic noise.
