Schurter expands its successful range of FMBC NEO 3-phase filters with a low leakage current series for applications where no high leakage currents are allowed. The new FMBC LL series of filters is designed for rated currents between 7 and 180 A. It is ideal for leakage current-critical industrial applications such as drive technology.
Long motor cables further aggravate the problem since they increase the capacity to earth and hence the currents to earth too. The new series of FMBC LL filters helps reduce the leakage currents and permits compliance with common EMC standards as an efficient input filter.
The compact FMBC LL 3-phase filters have been designed for currents from 7 A to 180 A at an ambient temperature of 50 °C. They have UL approvals for ambient temperatures of +50 °C as well as +40 °C at a higher rated current. The FMBC LL is approved for rated voltages of 520 VAC. This means that they can be used in high-power systems, such as machines used in an industrial environment. Despite their high output performance, they are still compact and
lightweight in design.
The standard FMBC LL is fitted with a screw connection. Other types of connections including wires or copper bars are possible on request as well as customised modifications to the circuit or housing. SCHURTER also offers its own EMC measuring service for an optimum adjustment to the inverter. Therefore the most efficient filter solution for the system can be developed.
