DIN-Rail Mountable AC-DC (DC-DC) Converters
Functional Description
The Convert Simply 15, 30, and 50 watt front-end modules are
flyback converters with a fixed frequency of 100 kHz (LOK) or
130 kHz (LOR, LOS). The battery charger modules and the
LOK4001-2RLD have a rectangular V/I output characteristic.
The rectifier modules have overload protection working in a
hiccup mode.
