ALE 500A Series. 1-40 kV, 500J/sec

The ALE model 500A 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 500A 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.

Options

Suffix-LH	"Low Inhibit" - A + 10 to 15 volt (high) signal will allow power supply operation. A 0 to +1.5 (low) signal will inhibit the supply.
Suffix-EN	"Low Enable" - A + 10 to 15 volt (high) signal will disable power supply operation. A 0 to +1.5 volt (low) signal will enable the supply.
Suffix-5V	0 to +5V programming = 0 to full scale output voltage (standard 0-10V)
Suffix-LP	Latching Overload Protection. Supply will latch off, requiring a reset if an overload condition occurs.
