PREFACE
THIS XENON POWER SUPPLY manufactured by Strong International is a dual-
chassis, high reactance 10,000 watt unit utilizing silicon diodes as the power conversion elements. All
models are designed for 50/60 Hertz operation, and are available in varying AC input types, depend-
ing upon the configuration of the main power transformers. Check the Equipment Data Plate to
determine the exact AC requirement prior to installation.
COARSE AND FINE TAPS are easily set to regulate the DC current to the xenon
bulb. Some models of this power supplies have the capability of overdriving a xenon bulb; carefully
check the power requirements specified by the bulb manufacturer and do not exceed the maximum
current stated.
DC OUTPUT to the xenon bulb is filtered by means of filter capacitors. A relay-
operated resistor circuit reduces the inrush current upon ignition to prolong bulb life. Suppression
capacitors prevent RF interference.
OVERSIZE HEAT SINKS disperse the heat normally generated by the silicon diodes.
Each power supply chassis include an internally wired blower for additional heat dissipation. Thermal
switches on the rectifier heat sinks act as safety interlocks to shut down the power supply and protect
the rectifier diodes in case temperatures reach excessive levels.
INSTALLATION
CHECK THE EQUIPMENT DATA PLATE and make certain that the AC source
conforms to the power requirements of the main power transformers. See the Installation Diagram
on Page 5 for detailed AC hook-up, line protection, and lamp connections. The AC service wiring
should be installed by a licensed electrician in conformance to local codes. The unit must be connected
to an adequate earth ground.
THE AC LINE to the xenon power supply must include a marked line safety switch
or other power disconnect device adjacent to the unit and accessible to the operator. For operator
safety, it is necessary to turn off all power to the unit when adjusting or servicing the xenon power
supply. This safety switch or power disconnect should be tagged “OFF - UNIT UNDER REPAIR”
when the power supply is being serviced.
