Theory of Operation

Fusing is provided by two in-line fuses on the AC input line.  Overvoltage 
protection for the VH, +24 VDC and +5 VDC supplied is provided by a 
“crowbar” circuit formed by a Zener diode and an SCR.  VH overcurrent is 
sensed and regulated by altering the oscillations of the pulse-width-modulator 
that generates the voltage.  Overheating is detected by a thermostat that also 
shuts down the pulse-width-modulator oscillator.
