ElectroPermanent Chuck Control Unit
- EPCU control units come in two different versions:
- SW for single wave rectified output voltage
- DW for double-wave (full wave) rectified output voltage
- Operational safety – the machine cannot be started up at a low holding force
- Safe magnetization level setting
- Effective demagnetization of the chuck and the workpiece for easy removal
- Control of the chuck via remote controller available
- Control one or more magnets at the same time (depending on selected unit type)
- One (1) year warranty
- Models 10SW and 10DW use U19 Control style. All other models use RM control style.
- U19: No channel selection possible but it can be used with EP-CU20 and 40
- Mag and demag cycles will start for all channels
- RM : Channel selection possible
The ElectroPermanent Chuck Control Units are designed to magnetize and demagnetize all types of ElectroPermanent magnetic devices depending on its factory settings. The magnetization cycles consist of one or several positive voltage pulses. The demagnetization cycles consist of a specific combination of alternating positive and negative voltage pulses. Note: The work piece material may retain some residual magnetism due to its chemical and magnetic properties.
When to choose the ElectroPermanent Chuck Control Unit:
The ElectroPermanent power supply and control units are designed to magnetize and demagnetize all types of ElectroPermanent magnetic devices, depending on its factory settings. MPI offers several control units depending upon size and number of chucks. In case of other magnetic device brands and models, consult MPI.
EPCU control units are named by the number of output channels (i.e., number of electrical circuits to be energized in the magnetic clamping system):
- EPCU10: 1 channel
- EPCU20: 2 channels
- EPCU40: 4 channels
EPCU control units also come in two different versions:
- SW for single wave rectified output voltage.
- DW for double-wave (full wave) rectified output voltage.
