dv/dt filter plus VPL (Voltage Peak Limiter) limit the voltage rate-of-rise dv/dt to values < 500 V/Ојs and the typical voltage peaks to the following values in accordance with the limit value curve according to IEC/TS 60034‑17: 2006:

• < 1000 V at U_line < 575 V
• < 1250 V at 660 V < U_line < 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), refer to dv/dt filter compact plus VPL.

Notice:

The max. permissible cable length between the dv/dt filter and Power Module is 5 m.
