These magnets are used to release axle braking, but may also work vice versa. Their operating voltages range from 24 V to 400 V AC and DC. Depends on what the customer wants to use. The magnets are supplied in full cast or as shown in the picture, as required by the user. The pulling force can vary from 10 kg to 200 kg. Performance ranges from 50 VA to 10 kVA. Magnets for AC use are provided with a compensating coil that provides no-noise operation.
