These Agilent branded HP Agilent 6654A 60Vdc 9 amp  540 watt power supplies are in good condition and have been fully tested, including the GPIB. They are guaranteed to pass NIST calibration. The unit you recieve may not be this exact unit; but will be in good condition. We have multiple units in stock.

• Fast, low-noise outputs
• Analog control of output voltage and current
• Fan-speed control to minimize acoustic noise
• Built-in measurements and advanced programmable features
• Protection features to ensure DUT safety

This series of 500 W linear-regulated DC power supplies is designed to maximize the throughput of DUTs through
the manufacturing test process with fast up and down programming time. Valuable assemblies can be destroyed
by a minor component failure that causes a surge of current to flow into the DUT. Fast protection features,
including fast crowbar, mode crossover protection, and the ability to connect the protection circuitry of
multiple power supplies can increase production yield. 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 acoustic noise.
