Solid State Rectifier
Solid State Rectifier Brake Rectifier / Power converter EH Series
EH-series brake rectifier is used to supply DC voltage to DC operated brakes on electric motors, where standard release reaction time of the brake is required.
The primary application of rectifiers is to derive DC power from an AC supply. This rectifier having capacitor & spark suppressor to protect the diode bridge circuit. Spark suppressor protects the coil and contact against impermissibly high induced voltages during DC switching. In the absence of a suppressor circuit, the induced voltage may exceed the permissible values and cause coil failure.
Rectifiers are available with half wave and full wave rectification. Rectifier can produce normal excitation and over excitation. These rectifiers are compact in size & easy to mount in terminal box or in control panel. Rectifier available with over excitation is used specifically with large DC coils for crane/Hoist brake application. This rectifier mainly used for spring applied electromagnetic brake. Also used for DC electromagnetic brakes, clutches, clutch brake combination. A connection diagram will be furnished with each rectifier or upon request.
