General

Description
The du/dt filter compact plus Voltage Peak Limiter comprises two components: the du/dt
reactor and the voltage-limiting network (Voltage Peak Limiter), which cuts off the voltage
peaks and feeds back the energy into the DC link. The du/dt filter compact plus Voltage
Peak Limiter is designed for use with motors for which the voltage strength of the insulation
system is unknown or insufficient.
du/dt filters compact plus Voltage Peak Limiters limit the voltage rate of rise du/dt to values <
1600 V/µs - and the typical voltage peaks to the following values according to limit value
curve A acc. to IEC 60034-25:2007:
● < 1150 V at U
● < 1400 V at 660 V < U
Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. This can also result in increased failures and reduced service
lives of braking resistors.
• Maintain 100 mm ventilation clearances above and below the component.
• Always mount the du/dt filters compact plus Voltage Peak Limiter in a vertical, upright
Risk of burns due to high surface temperature of the du/dt filter compact
The surface temperature of the dv/dt filters compact may exceed 80 °C. You can get
seriously burnt when touching the surface.
• Mount the du/dt filters compact so that they cannot be touched. If this is not possible,
