Divotech’s ER Series of high voltage power supplies are designed to meet the best performance standards. They are low ripple, air insulated, fast response units, with precision regulation and low arc discharge currents. OEM customisation available.


Input voltage
230v AC +/- 10%, 50 Hz
Output Voltage *
0 to 10/20/30/40/50/60/70/80/90/100kV DC
Output Current *
0 to 30 mA
Available with either positive, negative, or reversible polarity with respect to chassis ground.
Output voltage regulation
Line - < 0.05 % for 10% variation in input voltage Load - < 0.05% for 10 to 100% load variation
Output Voltage Stability
< 0.01%/hour after 1 hour warm up
Output Voltage ripple
0.05 % RMS of rated voltage at full load
Regulating Mode
Constant Voltage/Constant Current Operation: Automatic crossover from constant-voltage to constant-current regulation provides protection against overloads, arcs, and short circuits.
Voltage &Current Control
By external 10 turn potentiometers with lockable counting dials.
Against overload, over voltage, shortcircuit and arc:
Automatic current regulation protects against all overloads, including arcs and short circuits. Thermal switches protect against thermal overload. Fuses, surgelimiting resistors, and low energy components provide ultimate protection.
