Key features and functions
DIMET ПН-500 voltage transformers are designed for power supply, control and protection of load-bearing DC-electromagnets. Thanks to the high IP55 protection rating, they can be used in dusty environments
Key features and functions:
- Boost mode for the rapid increase of the current flowing in the electromagnets
- Demagnetization mode
- Display indicating the operating mode and fault conditions
- Stepless current control
- Limitation of maximum output voltage to 220-230 V
- 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
- Alarm when the maximum allowed current is exceeded
- Limitation for the maximum output current
