KEB rectifiers convert AC power to DC power and are used with all types of electromagnetic DC brakes and clutches. KEB rectifiers have UL and CE approvals.
COMBITRON offers a wide range of half-wave and full-wave rectifiers intended for worldwide use. KEB offers rectifiers with ratings up to 720VAC input.
The rectifiers have a robust design and are intended for demanding industrial applications. They contain internal MOVs which protect against voltage peaks of the switching contacts.
The rectifiers are able to switch on either the AC or DC side. DC switching allows for faster response times.
KEB’s rectifIers are extremely compact and can usually be mounted directly in the motor terminal box.
Also, DIN rail mount versions exist for easy panel integration.
They offer a reduced holding voltage option. These switches can be implemented to improve reaction time and reduce power consumption.
KEB offers overexcitation switches which provide a brake or clutch with higher than rated voltage for a small period (~350ms) of time. This shortens the actuation time of the device.
