Converter Topology Forward Converter
Operating Frequency 400 KHz
Overvoltage All models are protected against overvoltage.
Control circuit is preset so output voltage does
not exceed the following values:
Output V 24 48
OVP 32 60
Overload All models are protected against overload. The
control circuit has a foldback characteristic with
the knee set at 110% of full-rated load.
Recovery is automatic after removal of the fault.
