Dc-power Supply Reotron Smp-kma

Installation - Mounted on mounting wall


The REOTRON SMP power supplies are primary switched power supplies with galvanic separation from the input to the output. They can be used as voltage, current or power regulators.


The unit can be operated from an internal display, external control signals of 0…+10V, 0(4)…20mA or optionally by a Fieldbus interface such as DeviceNet, ProfiBus, CanBus, EtherCAT, EtherNet/IP and ProfiNet protocols.

Input devices

The device input is designed for connection to a three-phase main 3 x 400 V, 50/60 Hz. The compliance of EMC standards is guaranteed by an input-sided PFC-mains filter.


The devices have a compact design in a 19-inch rackmount chassis and can be delivered as an installation-ready control cabinet version or as a tabletop unit (lab version). The devices are air- or water-cooled.


The SMPs are connected via screw terminals and with cooper terminal buses at high output currents. Like all REO products, the REOTRON SMPs are also available as customized versions.

High range of performance

The units can be combined to power supplies with higher ratings by connecting the units in series or parallel.
