Power
1.4.1 3kW Lamp Power Supply (LPS)
The 3kW lamp power supply provides the main lamp power for the system. It is connected via the anode and
cathode cables and two signal cables. One signal cable is for RS232 control and diagnostic feedback and the
other carries hardware interlock signals to protect the projector if airflow or access panels are disrupted. It is
wired into the power mains to a single phase power supply with a range from 200 VAC to 240 VAC. The
electronics control the power output from 3kW down to 1kW depending on the lamp type and power level
required. An IEC 320 connector is provided to optionally power the projector electronics (with the exception of
the LPS) from an Uninterruptable Power Supply (UPS) – this allows the electronics to keep power during a
power failure; the lamp will not run. Ultimately this enables a fast re-strike and play once power is back ON.
1.4.2 Low Voltage Power Supply (LVPS)
The LVPS provides all of the power to the projector in full power mode, with the exception of the TPC which
is powered by the standby power supply.
• In full power mode the main rail supplies the Environmental Board (EVB), Intelligent Motor Control Boards
(IMCBs) and the Projector Intelligence Board (PIB3G). NOTE: In stand-by the PIB3G only allows commu-
nication and upgrades to occur without switching to Full Power.
• The 12V main rail supplies the ICP, fans and pump and LPS opto-isolators.
1.4.3 Standby Power Supply
The standby power supply is a fanless 24V power supply that supplies power to the TPC, the UPS input (if
wired this way) and the field wireable AC input. It also supplies a minimum amount of power to the IMCB for
holding stepper motor positions.
1.4.4 Igniter
The igniter is located in the lamp compartment. It is powered by the 3kW lamp power supply located at the
back of the projector. The lamp power supply connects to the igniter with an anode cable, which is routed along
the baseplate of the projector closest to the lamp door.
