All specifications

A glance at the most important advantages

  • Ensuring safety during operation
  • Early signaling power supply problems.
  • Monitoring the power supply
  • Protection against short circuits

Key features and benefits

DIMET ПН-500 Г-voltage transformers are designed for power supply, control and protection of load-bearing DC-electromagnets. Thanks to the high IP55 protection class, they can be used also in dusty environments.

 

Key features and benefits: 

 

  • Limitation of the maximum output voltage to 220-230V
  • Boost mode for the rapid increase of the current flowing in the electromagnets
  • No energy recovery to the power grid when the electromagnet is switched off
  • Demagnetization mode 
  • Display indicating the operating mode and fault conditions
  • Stepless current control 
  • Load short-circuit protection 
  • Cross-circuit and ground fault protection 
  • Alarm in case of cable break 
  • Alarm for exceeding the leakage current in the electromagnet circuit (in case of overheating of the electromagnet)
  • Alarm for short circuit between the electromagnet windings  
  • Limitation for the maximum output current
