Product Description:
The 02.91.020-CE07 is a compact rectifier module produced by KEB for the COMBITRON Rectifiers series. Designed for control panels and small drives, this device converts alternating voltage into direct current so that brake coils, contactors, or PLC inputs receive a steady DC supply. Its small footprint allows placement close to the load, reducing wiring lengths and improving response time in industrial automation circuits.
The electrical profile of the module centers on its input window of CE 275 VAC - UL 240 VAC, allowing operation on European or North-American mains without readjustment. Inside, a Full Wave diode bridge rectifies the incoming line, producing a smoother DC curve than half-wave designs and lowering ripple on sensitive loads. At an ambient temperature of 45 °C the unit can deliver 2.0 A of continuous output current, while the specification lists a switching path of AC/DC, indicating that the device is placed between an AC source and a DC consumer. An enclosure rating of IP20 protects the internal components from accidental finger contact and limits dust ingress, fitting indoor cabinet environments where forced convection is typical.
Thermal and installation limits govern practical use. The rectifier remains functional up to 80 °C ambient, matching the high-temperature tolerance required near motors or braking resistors, and its climatic rating of 3K3 defines suitability for dry, non-condensing machine rooms. Physical dimensions of 37×25×17 mm permit mounting on dense terminal rows, while a conductor area of 1.5 mm² can be clamped in each terminal. Fastening torque is 0.5 Nm, ensuring reliable connections without damaging the housing. When cabinet temperatures rise to the specified maximum, the continuous output current derates to 1.0 A, maintaining semiconductor junction safety under prolonged load.
