Specifications
- Power supply, control and protection of DC lifting solenoids when operating from the AC power supply system
- Electromagnets
- Crane equipment
- Equipment for metal scrap handling
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
