Description

The dv/dt filter with Voltage Peak Limiter consists of two components: the dv/dt reactor and
the voltage limiting network (Voltage Peak Limiter), which limits voltage peaks and returns
the energy to the DC link.
The dv/dt filters with Voltage Peak Limiter must be used for motors for which the voltage
strength of the insulation system is unknown or insufficient. Standard motors of the 1LA5,
1LA6 and 1LA8 series only require them at supply voltages > 500 V +10%.
The dv/dt filter with Voltage Peak Limiter limits the voltage gradient to values < 500 V/µs and
the typical transients with rated line voltages to the values below (with motor cable lengths of
< 150 m):
< 1000 V at V
