E-P Chuck Control Units

Description and function

EP chuck control units convert the AC (alternating current) power supply into DC (direct current) to power up the coils of the chuck with short current rushes.

A microprocessor based control board in the unit allows selecting the right function with optional adjusting the clamping force of the magnet as well as automatic demagnetization.

Variable holding force

A rotary button on the remote control station allows output voltage adjustment resulting in variable holding force. This prevents any deformations that would result from too strong a clamping force

Automatic demagnetization

The magnetic chuck and the workpieces can be completely demagnetized.

Depending on the type of steel, different demagnetizing programs can be selected.


Apart from the fact that our control units comply with the IEC electrical standards they also comply with the provisions of the European Machinery Directive 2006/42/EC. A safety contact inside the unit blocks the starting of the machine if the magnet is not switched on or if the holding force is too low.

Available control units

  • Without enclosure, protection class IP00 for integration in the machine’s control cabinet
  • Built into steel enclosure, protection class IP54, for wall mounting
  • Standard input voltage: 400 VAC
  • Choosing the correct control unit depends upon the type of chuck, the chuck size or the total size of multiple chucks.
