Band-pass electronic filter NFK885-20A42

passivethree-phaseDIN rail

Filters of the NFK885-A series are used to suppress circuit-bound interferences in three-phase AC power lines without neutral conductor. Interference pulses or interference voltages are dampened independently from their point of origin. To improve the filter effect they are designed with 2 stages, furthermore these filters are optimized against asymmetric interferences and have a high insertion loss on a broad frequency range. High insertion loss over a broad frequency range Optimised against asymmetric interferences Using aluminium enclosure in order to improve the heat conduction Suitable for the tropics - epoxy resin casted Safety acc. to VDE, EN, UL, CSA Inductance: - 4 x 1.3mH + 4 x 1.3mH Capacity: - 9 x 1.0µF + 5 x 22nF Operating temperature range: - -50°C / +85°C Dimensions (WxHxD): - 94.0 x 100.0 x 120.0 mm Weight: - 2.45 kg
