Page 10: Product Description
3 Product Description 3.1 Scope of this Manual The KEB COMBITRON 91 is a rectification unit designed exclusively for supplying energy to electromechanical clutches and brakes. The unit employs a rectifier to convert incoming AC into DC. The units utilize rectifiers configured as either full-wave or half- wave circuits in order to match the supply voltage to the coil voltage. -

The advantage to DC side switching is the speed of the brake reaction. The delay time associated with brake engagement can be reduced by over a factor of ten compared to AC side switching. This results in faster control of the mechanical system which may provide better safety. 2021 KEB America, Inc. ©... -
