Power supplies

SITOP modular

A reliable 24-V power supply is a basic condition for every plant operation. With MTBF ratings of up to 1 million hours at full load in continuous operation, SITOP power supplies meet the particularly stringent requirements for process automation.

For world-wide use, the 1, 2 or 3-phase DIN rails provide a wide ambient temperature range of -25 … +70 °C as well as comprehensive international approvals such as ATEX, Class I Div2, IECex or GL.

The innovative SITOP PSU8600 power supply system can be fully integrated in the plant via PROFINET and thereby offers completely new configuration and diagnostic capabilities. It is thus possible to individually adjust and monitor the voltage and current of each output. For the first time, users have access to information about the control circuit including energy flow data.

SITOP add-on modules and UPS1600

24 V power supply units with output capacities up to 1000 W can be individually adapted to the plant configuration and plant expansion and combined with redundancy, selectivity or DC UPS modules. This means that you can expand the system to even include complete all-round protection.
