Functional Description and Block Diagrams
These converters are primary controlled flyback converters
using Pulse With Modulation (PWM). The output voltage is
monitored via a separate transformer winding very close to
the secondary winding(s) and fed back to the control circuit.
This is the reason why double and dual output units should
always have the same (%) load conditions at both outputs
to comply with the specified data. The current limitation is
located on the primary side, limiting the total output current.

The converters of groups 04 and 05 are designated as CPS 3 types. The type variety and all specifications are the same as for the
IPS 3 group 01 and 02 with the exception of the shutdown function which is not available.
