Electronic-Pole-Reversal-Control-Unit 757
The Electronic-Pole-Reversal-Control-Unit 757 is a controllable current or voltage source for magnetising and reversing the polarity of electromagnets
It is operated via 24 V DC control inputs. The system statuses are displayed via 4 LEDs.
A polarity reversal process is required to reduce the residual magnetism when switching off electromagnets. This generates a magnetic field that changes polarity and decreases in intensity. This process ensures that the residual magnetism is reduced to a minimum. The USG 757 regulates the necessary currents / voltages through the magnet. A basic factory setting of the electrical nominal values is carried out when the USG 757 is delivered. If required, the polarity reversal process can be changed by selecting a different polarity reversal programme. It is also possible to change the polarity reversal programmes and the holding force levels individually using the optionally available monitor programme.

With the optional multi-magnet mode, up to four data sets of different magnets can be saved. The data records contain all the data relevant for solenoid control. This means that up to four different solenoids can be operated alternately on one pole-reversal control unit.
ACCESSORIES:
Power supply units for the DC supply:
For the DC supply of the USG 757, we offer suitable switching power supply units for single-phase and three-phase mains connection in various power sizes
Control unit
We offer various type 744 control units for manual control of the pole-changing control unit. These are equipped with a coding switch for setting the holding force and with illuminated buttons for energising and reversing the polarity of the solenoid. buttons and coding switches are also available as built-in parts.
