PNS series

The PNS series magnet control units (voltage transducers) are designed to control any types of lifting magnets or groups of magnets totaling the maximum operational amperage at 125A (PNS-300) and 200A (PNS-600) at Tmc = 20 °C)*.

* * Tmc - temperature of the magnet's coil.

The following are the basic advantages of the PNS series control units as compared to the currently in-use PMS-15 series and the like:

• Stepless adjustment of the magnet's voltage
• separation of trasferred loads
• Power saving (recuperatiom mode) through elimination of ballast resistors from the crane's circuit and release of the power accumulated in the magnetic field back into thr supply line
• High-speed electronic devices protect the magnet from breaking and short-circuiting the cable's strands among them or their ground-circuiting. Also we have achieved the reduction of overvoltage at degaussing by the power-line's own amplitude. All these facts account for the lengthening of the product's life-time.
• Small size and mass allow to install the trancducer directly inside the crane cabin in a convenient for the operator location.

Additional advantages:

• Maximum operational amperage (125A and 200A)
• Advanced operation mode indication
• Patent clearance
