You are viewing an auction for a Wallis Hivolt -5kV @1MA DC power supply circuit board with a 0-5V external control input with 5V yielding a -5kV DC output. Output cord is is approximately 13.5 inches long. Supply dimensions are 4-1/2" long, 4" wide and 1-1/2" tall. Input voltage requirement is 24VDC.
There is a small nick in the output cord approximately 1-1/8" from the supply which does not appear to be an issue. Supply board is identical to one sold in another auction that has an enclosure. Supply produces -5kV @ 1MA as shown in the images. Supply is tested working and is sold as-is. Voltage measurements indicated on the Fluke 87 are through a Fluke 80K-40 (1000:1 ratio) high voltage divider/probe.
Auction is only for the Wallis Hivolt supply PCB. Test equipment and resistors are used to prove functionality and are not included.
