About this chapter
This chapter describes briefly the functionality, the parts, the diagnostic LED’s and the replacement of the Lamp Power Supply (LPS).
Functionality
The Lamp Power Supply (LPS) of the FLM projector is actually a dual LPS connected in parallel. Both LPS units are enclosed in
one casing. The front side of the LPS casing contains the input/output connectors and diagnostic LED’s of the LPS units. The rear
side is equipped with fans. The whole LPS module slides into the LPS compartment at the rear bottom of the FLM projector and
can easily been replaced.
To ignite the lamp the voltage on the output pins of the LPS units is brought up to 140 volt. This high voltage will trigger the Start
Pulse Generator (SPG) to ignite the lamp. Once the lamp is ignited the voltage on the output pins of the LPS units is dropped to the
typical arc voltage of the lamp e.g. 28 volt for a 3 kW FLM lamp.
Each LPS unit can deliver maximum 2500 watts and maximum 100 amps. In normal situation, each LPS unit deliver the half of the
required power. So, for a 3 kW lamp having an arc voltage of 28 volt, each LPS unit deliver 53,57 amps at 28 volt which is equal to
1500 watt.
When one of the two LPS units suddenly fails during the event the other LPS unit will continue delivering 53,57 amps at 28 volt. As
a result the projectors light output will be reduced. In case the projector starts up and one LPS unit remains down the other LPS unit
will run on its maximum power and deliver 89,3 amps at 28 volt which is equal to 2500 watt.
In case one or both LPS units fails an error will be displayed on the LCD panel of the projector.
