ARC LAMP POWER SUPPLY

OUTPUT AND CURRENT PREADJUST SWITCH
A ten turn potentiometer is used to provide a precise means of output current adjustment. A shaft
lock is mounted with this knob to lock in a setting if a readjustment from a previous current setting
is not desired. When the preadjust switch is pressed the meter will display the value of the output
current that will be delivered to the lamp after lamp start.
POWER SWITCH
This is the AC mains power switch. In the “ON” position ac power will be switched into the main
circuitry of the power supply, and an integral indicator lamp will glow to indicate that the power
supply is on. The power switch is also a circuit breaker which will open both of the ac lines to the
internal circuitry in case of a fault within the unit.
