dv/dt filters plus VPL
Обзор
dv/dt filters plus VPL (Voltage Peak Limiter) limits the voltage rate-of-rise to values < 500 V/μs, and the typical voltage peaks to the following values according to the limit value curve to IEC/TS 60034-17: 2006:
< 1000 V at Uline < 575 V
< 1250 V at 660 V < Uline < 690 V
Standard motors with standard insulation and without insulated bearings with a supply voltage of up to 690 V can be used for converter operation if a dv/dt filter plus VPL is used.
dv/dt filters plus VPL are designed for the following maximum motor cable lengths:
- Shielded cables: 300 m (e.g. Protodur NYCWY)
- Unshielded cables: 450 m (e.g.Protodur NYY)
For shorter cable lengths (100 m shielded, 150 m unshielded) also refer to dv/dt filter compact plus VPL.
Notice: The maximum permissible cable length between the dv/dt filter plus VPL and the Power Module/Motor Module is 5 m.
