PFC overvoltage protection
1. If input overvoltage or undervoltage protection is triggered, both MV12 and MV6 are shut down. The input
voltage threshold that causes MV12 to shut down is the same as the input voltage threshold that causes
MV6 to shut down.
2. If input overvoltage or undervoltage is rectified, both MV12 and MV6 recover. The input voltage threshold
that causes MV12 to recover is the same as the input voltage threshold that causes MV6 to recover.

Latch-off mode
Latch-off mode
In the MV6 mode, if
the PSU loop is
detected to be
open, protection is
triggered directly
without having to
reach the MV6
