dv/dt filters compact plus VPL (Voltage Peak Limiter) limits the voltage rate-of-rise dv/dt to values < 1600 V/μs, and the typical voltage peaks to the following values according to the limit value curve A according to IEC 60034‑25: 2007:
< 1150 V at Uline < 575 V
< 1400 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 compact plus VPL is used.
dv/dt filters compact plus VPL are designed for the following maximum motor cable lengths:
For longer cable lengths (> 100 m shielded, > 150 m unshielded) refer to dv/dt filter plus VPL.
