Output filter Du/Dt FSC 3025, for inverters up to 7.5kW FSC3025

Output filter Du/Dt – inverter protection and motor lifespan extension

The Du/Dt FSC 3025 output filter is a key component of an installation with a 7.5 kW inverter. Its task is to reduce electromagnetic interference and overvoltages that occur during inverter operation. Installing the filter between the inverter and the motor is a simple solution that significantly affects the reliability and durability of the entire system.

This filter is designed to work with frequency inverters, minimizing leakage currents and interference. Limiting short-term overvoltages generated during inverter commutation directly translates to extending the lifespan of both the motor and the power cables. This is particularly important in industrial applications where failures can generate high downtime costs.

Construction and user parameters

The FSC 3025 is characterized by compact dimensions (57 x 100 x 105 mm) and an IP20 degree of protection, which ensures safe use in most industrial environments. Screw terminals facilitate the connection of wires with a maximum cross-section of 6 mm². The filter has a rated current of 25A and an inductance of 2.5 mH and a resistance of 6.8 mOhm. This makes it perfectly matched to work with 7.5 kW inverters.

It is important to remember to select the correct wire cross-section – a maximum cross-section of 6mm² is recommended. This will ensure optimal filter performance and installation safety.
