Strong xenon, Instruction Manual

Page: 3 / 18

PREFACE
THE STRONG INTERNATIONAL switching power supply Type 62-80100 is
designed to operate a xenon bulb in all theatrical lighting applications for Strong lamphouses. This
unit will operate all xenon bulbs rated from 1000 to 3000 watts throughout their full operating ranges
(20-35 V.DC, 40-100 A.DC). The power requirement for this unit is 208/230 (200-240) V.AC, 30
amperes single or three phase, 50/60 Hertz.
INCOMING LINE POWER is transformed from 208/230 volts AC to a low voltage,
high current DC output. The incoming AC line is filtered to eliminate noise and is then converted to
DC. This DC voltage is switched on and off by a solid state switching circuit, and converted to a 60
kHz. square wave. The square wave is fed into output transformers to provide low voltage and high
current. Rectifiers convert the 60 kHz. signal to DC, and the output is filtered to eliminate noise and
ripple. Output to the xenon bulb is adjustable through use of potentiometers.
A STEPDOWN TRANSFORMER reduces the incoming line to 120 V.AC to power
the lamphouse igniter and blower(s). A separate three ampere circuit breaker protects the control
circuit in the event of a lamphouse component malfunction.
PROTECTIVE CIRCUITS include a high temperature limit switch and under- and
overvoltage detection. The thermal switch will open and interrupt power supply operation if internal
temperatures exceed 175° F. (80° C.). A drop in AC line voltage, reducing AC supply to inadequate
levels, or a high voltage AC spike, will also disable the power supply until the voltage is corrected.
A MULTI-PIN MS RECEPTACLE is standard on units supplied for use with Strong
follow spotlights and projection consoles. A lamphouse termination panel may be ordered as an
option for motion picture or studio applications using Strong lamphouses without the corresponding
MS plug.
NOTICE
REFER ALL SERVICING of this unit to an authorized Strong International
Equipment Dealer. The 62-80100 Switching Xenon Power Supply employs
solid state circuitry requiring sophisticated diagnostic equipment not gener-
ally available to field service personnel. Hazardous high voltages exist within
the power supply cabinet.
