This is an HDR Power Supply 3000 amps and 80 volts.
This is a 480 Vac power supply and is controlled with 4 to 20 milli-amps to control 0-3000 amp constant current
This unit can run as a stand along power supply with the potentiometer on the front. It can also be remotely controlled!
HDR still supports this power supply with any of its needs as of 2012
These were used by NASA in experimental work so they are lightly used.
These are in good condition; we have 2 available. One is fully tested and ready.
