Fully encapsulated three-phase dv/dt Filter (IP20)
Description
Reduce voltage rise to < 500V / µs – protect electrical loads and insulation cost-effectively.
A simple and inexpensive method of reducing the rate of voltage rise is to use a du / dt filter. The filter dampens the voltage rise to acceptable values and prevents overvoltages on long supply lines. Losses and heating are minimised and the leakage current is reduced. By limiting the voltage gradient, the motor insulation is protected and the service life is extended.
EMC interference in the radiation range from 1 MHz to 30 MHz is also reduced.
Voltage rises are reduced to < 500V / µs.
Advantages
- Optimal mechanical protection of the reactor
- Optimal mechanical protection of the choke
- Protection for electrical consumers
- Limit the voltage rise to <500V/µs
- Extended service life of electrical consumers
- Low leakage currents on the motor
- Reduced losses
- Very low noise
- Easy construction
- Production possible according to UL insulation system E251513
