Power supplies

The General Power Supply provides a range of low voltage rails to the electronics.
The Xenon Arc Lamp has a separate high current power supply.
High Voltage, Danger of Death - the arc lamp power supply has a 30kV strike
pulse mechanism, which is active during lamp switch-on.

Cooling System

During normal operation considerable heat is generated inside the projector,
therefore, an air cooling system is provided. This consists of a powerful fan which
draws cool air through specially designed air ducts within the case to distribute it
over the lamp and other components. The cooling system provides maximum
cooling whilst minimising noise output.
Do not move or tamper with any seals or ducting panels on the projector or the
air flow could be disrupted and cause the projector to overheat. Always keep the
air inlets and outlets clear of any obstruction.
