DV/DT filter, Rated Current 6A for 2.2KW motor

Model: SKS-DVT-0007-4C-10
Dv/dt filters Description The SIKES DV/DT filters decreases the insulation stress of motors by lowering the dU/dt value of the variable speed drive output voltage. It can be utilized with cable lengths up to 100 to 300 m depending on the model. Moreover, the units are intended for maximum switching frequency of 200 kHz. The filters create less heat with smaller switching frequencies. The motor is not intended for utilizing with a variable speed drive to retrofit applications. Du/Dt filter is economical alternative for Sine wave filter.

Features

Os filtros dv/dt podem apoiar nossos clientes:
1. reduzindo efetivamente a tensão dt/dv nas extremidades do servomotor do inversor;
2. prevenindo o envelhecimento precoce e a ruptura do cabo de transmissão e da bobina do servomotor;
3. prolongando a vida útil dos servomotores e o período de operação, melhorando a confiabilidade do servo;
4. reduzindo a interferência em equipamentos e circuitos próximos;
5. reduzindo a corrente de fuga de aterramento do motor;
6. reduzindo a interferência quando o contator entre os filtros e os motores é ligado;
7. reduzindo efetivamente a tensão de pulso de pico nas extremidades do servomotor;
8. atendendo aos requisitos de saída das normas IEC 60034-17, 60034-25.
