4.9 Filament Transformer Module
The filament power supply provides an A.C. voltage for filament operation. The frequency of
operation is 34 kHz. The filament transformer provides 10 volts at 75 amperes maximum to the
filament for operation. The filament transformer has a single turn secondary providing the power.
The 40 mills thickness of copper connects to the two brass studs located in the G-10 output plate.
CAUTION
During operation 10kV, 10,000 volts DC, is connected to these studs. The filament
transformer housing provides protection for personnel. The filament output wires are located
in a flexible metal conduit. The conduit connects to the customer’s assembly where the filament
wires are protected from access during operation.
The circuit breaker on the power supply chassis should be OFF anytime access is required in the area
of the box.
Vacuum Relay: The box contains a vacuum relay that connects the high voltage cable to the
transformer secondary.
Microswitch: The box cover is interlocked and will drop out high voltage or prevent high voltage
operation anytime the cover is not in place.
5.0 TROUBLE SHOOTING
5.1 Equipment
The power supply system is packaged in three separate assemblies:
A. Power Supply Chassis
B. Control Assembly
C. Output Transformer Module
In addition, there are interconnect cables and customer connections required.
The power supply system has several protection features that must be reset and or replaced before
operation can begin.
Power: Make sure the input voltage matches the input voltage stamped on the rear panel of the
equipment. Make sure all three phases of the power source is present. . Note: A neutral connection is
required on 400 V inputs; make sure it is connected.
Circuit Breakers: There are several circuit breakers protecting the equipment. Make sure they are in
their ON position.
Main Circuit Breaker: Front Panel
Filament Supply Circuit Breaker: Rear Panel
Control Circuit Breaker: Rear Panel
Fuses: There are fuses in the system protecting low power circuits. Make sure the fuses are in place
and in functioning condition.
