Noise filter product offering expanded

11 June 2008 Circuit & System Protection

Cosel has added four new models to its range of noise filter products.

The NBH series is designed for ultra-high attenuation of common-mode noise from 10 kHz to 10 MHz. The two-stage filter is designed for single-phase 250 V a.c. systems and features selectable leakage current and a withstand voltage of 4000 V a.c.

The NBC series achieves high attenuation of common-mode noise in the range from 150 kHz to 1 MHz. It is also a two-stage filter designed for single-phase 250 V a.c. systems and features selectable leakage current.

The NBM series is designed for low leakage current applications in single-phase 250 V a.c. systems. The two-stage filter features selectable leakage current and a withstand voltage of 4000 V a.c.

The SNR series is a ripple noise attenuation type device for switch mode power supplies operating up to 50 V d.c.

All new models offer a DIN-rail installation option, are RoHS compliant and feature a five year warranty. They also carry various safety approvals, including UL and EN.
