Power Supply And Ac Filter Eca - InFocus X2 Service Manual

Power Supply and AC Filter ECA

The power supply (510-1894-xx) and the AC filter ECA fasten to a metal chassis. Both parts are
included in the power supply kit (520-0124-xx).
The AC filter ECA includes the AC power connector and filtering components that help ensure clean
power reaches the major projector components. The AC filter ECA connects to the power supply ECA.
The power supply ECA includes both the ballast and power supply circuitry in the X2.
A fuse on the AC filter ECA protects against internal shorts or supply surges. The fuses are not available
as FRU parts as a blown fuse usually indicates circuit damage and the need for ECA replacement.
You can replace the power supply and AC filter ECA independently.
DANGER Do not attempt to measure the output voltage from the ballast when the lamp strikes. High
voltage produced by the ballast to strike the lamp can ruin test instruments as well as cause
personal injury.
