Description

Manufacturer: Bertan

Model: 225-01R

Condition: Used. Comes in non-original packaging. This supply is in fair cosmetic condition with lots of minor scuffs and scratches, especially on top, and some minor adhesive label residues from prior use. Please NOTE: We are 99% sure this uses an MHV type connector for J1 high voltage output, which almost mates with a BNC connector
The photos show the exact item(s) the buyer will receive.

Notes: This supply is in good working condition as far as we can test. We can't test the remote programming functions or measure maximum output voltage. We are only equipped to measure up to 500 V, so we verified voltage in both polarities up to 500 V. The voltage indication matched our own meter. The maximum indicated voltage is 999.7 V. The minimum indication doesn't quite go to 0 V, but we measured 0.0 mV output. We strung about 33 k ohms (a mix of power resistors) in series on the output, and indicated currents made sense, (3.05 mA at 100 V, 15.24 mA at 500 V, and 30 mA at 987 V). The buttons, output High Voltage switch, polarity switch and adjustment knob all worked as expected. The adjustment bears special mention, because it is highly intuitive. Very-slow rotation gives slow-millivolts changes, and a big crank of the knob can change by the full 1 kV with a flick of the dial. The unit identifies itself at startup as 225.01. No other testing was done.

No manuals, cords/cables, or additional items are included if not listed or shown.
