DESCRIPTION
The DC power supplies from the REOTRON SMP series are primary switched switching power supplies with galvanic isolation from the input to the output. The devices can be used as voltage, current or power regulators.
Operation
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 mains 3 x 400 V, 50/60 Hz. The compliance of EMC standards is guaranteed by an input-sided PFC-mains filter.
Design
The devices have a compact design in a 19 inch rackmount chassis and can be delivered as a installation ready control cabinet version or as a tabletop unit (lab version). The devices are air- or water-cooled.
Connection
The SMP‘s are connected via screw terminals and with cooper terminal buses at high output currents. Like all REO-products, the REOTRON SMP‘s are also available as customized versions.
Advantages
- Very good cos Φ of 0,95
- Compact dimensions
- Series or parallel connection
- Air or water- cooling
- Many options of combinations for different requirements with other
