Product Description:
KEB produced the 06.91.010-CE09 for the COMBITRON Rectifiers series. This unit is a compact rectifier block that sits between an AC supply and DC brake coils in automated machinery, changing line voltage into a steady direct current needed for fast brake engagement. The module integrates easily into control panels and can share the same supply that powers contactors and drives. By isolating the braking circuit from the main inverter output, it improves stop accuracy and reduces electrical stress on the drive.
Electrical limits indicate where the rectifier can be used. It accepts an input synchronized to 50/60 Hz grids and should be protected by a fuse rated at 5 A to safeguard its silicon bridge. The internal semiconductors withstand a peak reverse or interrupting voltage of 1600 VAC, letting the device tolerate transients that may appear on busbars. Conversion is performed through half-wave rectification, so one half-cycle of the AC waveform is passed and filtered to energize the brake coil without reversing current. Housing compliance of IP20 indicates that the enclosure blocks finger contact but still requires installation inside a cabinet. The 180–300 VAC input variant, together with a CE rating of 720 VAC and a UL rating of 240 VAC, places the module in control circuits within that voltage range.
Thermal and clearance limits complete the operating range. Continuous service is allowed up to 85 °C when derating guidelines are followed, permitting use near motor frames or warm inverter stacks. Field wiring is aided by a terminal pitch that leaves 9.5 mm of space, which helps maintain dielectric distance in dusty shops. Under UL tests, the rectifier draws only 0.6 A from the supply while delivering 216 VDC to spring-applied brake coils. These figures fit climatic category 3K3, so reliable operation is expected in switchgear rooms with moderate condensation and contaminants.
