Summary
The Convert Simply 50 front end modules represent a fam-
ily of 50 watt DIN-rail mountable AC-DC converters for use
as rectifiers or battery chargers. Fully encapsulated plastic
case, compact size and high reliability make the OK series
an excellent choice when a DIN-Rail mountable AC-DC
converter in space critical applications is required. The uni-
versal input range and a built-in input filter allows flexible
operation in a wide variety of electronic equipment and ena-
bles world wide connection to the mains.
The units are available as rectifiers with 12 V or 24 V single
outputs as well as battery chargers for 12 V or 24 V batter-
ies. The output voltage can be adjusted via the R input.
Safety approvals and EMC fully comply with world wide re-
quirements.
Key applications
Typical applications are: powering building controls, factory
automation, industrials controls, instrumentation, electro-
magnetic drives, fans and other DC loads.
