The ALE model 102A is an OEM style High Voltage Power Supply designed for operation in two modes. In the most common format it is a constant current Capacitor Charging Supply which will reliably charge HV capacitors and Pulse Forming Networks (PFN's). The 102A can also operate as a constant voltage, continuous output DC Power Supply with the addition of an external filter capacitor. The entire OEM series supplies employ ALE's patented parallel resonant inverter topology which results in superior pulse to pulse repeatability compared with conventional series resonant designs.
