Brake control gear can be supplied for use with DC magnetic brakes with one or more of the following functions.
- Rectify the AC supply (1ph or 3ph) to provide dc for the brake coil.
- Reduce the brake operating time, eg to give a fast response on hoist brakes.
- Reduce the brake release time.
- Reduce the brake voltage after operation, to reduce brake coil heating, eg if duty cycle is arduous or ambient temperature is high.
