The CineLife+ 4K-RGB power supply assembly includes individual 12V and 48V power supply modules
secured within a support bracket.

The 12V power supply module provides the required voltages for operating the electronics in the
projector and for receiving a UPS connection (if installed).
The 48V power supply module provides the required voltages for the lasers and pumps.
Before servicing, always carefully observe the original lead dress. Take extra precautions to secure all
harnessing properly, especially in the high voltage circuitry areas. Replace any wire that appears to
have damaged insulation.
