All voltage ZVS converters are isolated (1500V isolation voltage) and fed via a common Filter Network from
the same 28V main supply (18V – 35V, shortly 36V). 3V3aux is not independent but protected by a
resettable fuse (PTC). All individual output voltages (6x) are sensed by window comparators for over- and
under voltages which are monitored from a central control logic device (CPLD). Any failure on the output
voltages are signaled on the front panel by corresponding FAIL LEDs and lead to a switch off of all voltages
(by default). If all internals are normal the blue READY LED is working. Figure 1 show gives an overview
over the front panel elements.
