ASSYMETRIC BIPOLAR PULSED-DC POWER SUPPLY
+40V TO -800V PULSED-DC, 50W TO 5KW
ASSYMETRIC BIPOLAR PULSED-DC POWER SUPPLY
+40V to -800V Pulsed-DC, 50W to 5kW
This series of power supplies generate alternate pulses of opposite polarities. The output voltage, pulse width and the pulse frequency are all controllable through 10 turn potentiometers and switches.
