Voltage converters are specially designed to supply and control lifting direct current electromagnets of any power and simultanious supply of several electromagnets with summary current not exceeding allowed values.
Peculiarities:
1. Increase of the electromagnet service life perod owing to the high-speed election protections and emergency alarm in the course of operation.
2. Overvoltage is missing during recuperation and demagnetization.
3. Continous voltage adjustment, opportunity to separate materials moved by a conveyer.
4. The output increases due to growing in speed of a current buildup and dropping in an electromagnet.
5. Universality - they are intended for the iron separators with 100% duty cycle rating.
6. Alphanumeric display of the running parameters, operating regimes and emergency messages.
7. Sound emergency alarm.
8. Small weight and sizes allow to place a changer of series PN-500 proximately in the crane-s cabine in any place suitable for an operator.
9. At the request of the customer the control system is completed with the remote board.
10. High reliability is achived through a new element base and original designs covered by Russian patent law.
