DV/Dt -Choke N CNW 806
Three-phase-dv/dt filter
Description
NEW PRODUCT RANGE!
The new series not only scores with a faster delivery time, but also with the conservation of resources and increased efficiency.
Reduce voltage rice to < 500V/µs – electrical consumrs and insulation will protected with low costs.
A simple and inexpensive method for reducing the rate of voltage rise is to use a du / dt filter or throttle. It dampens the voltage rise to acceptable values and prevents overvoltages on long supply lines.
Losses and heating are minimized and the leakage current reduced. By limiting the rate of voltage rise, the motor insulation is protected and thus prolongs the life.
Also, the electromagnetic interference can be reduced in the radiation range of 1 MHz to 30 MHz.
Advantages
- Protection for electrical consumers
- Limitation of the voltage rise on <500V / us
- Extended service life of electrical consumers
