Power supply maker Cosel, which entered the noise filter business last year, offers various types of noise filters. As industrial equipment is now being made lighter and smaller, with lower profiles and shorter lengths, the noise emanating from the equipment itself and the noise affecting it from external sources has become problematic.
In order to comply with strict EMC standards a noise filter becomes a necessary item for various applications. Cosel has developed noise filters that complement its power supply range, to enable customers to solve noise problems in their products. New products include:
* Single phase series:
NAC: High-attenuation for common mode noise from 150 kHz to 1 MHz.
NAH: Ultra high-attenuation for common mode noise from 10 kHz to 1 MHz.
NAM: Low leakage current type.
NAP: External pulse voltage attenuation.
* Three phase series:
TAC: High-attenuation for common mode noise from 150 kHz to 1 MHz.
TAH: Ultra high-attenuation for common mode noise from 10 kHz to 1 MHz.
* ±50 V d.c. series:
SNA: Ripple noise attenuation for DC switch mode power supplies.
Cosel's noise filters allow users to select appropriate leakage currents in order to meet leakage current requirements on their systems and comply with EMC. Wiring work is eased as pushdown terminals enable users to connect with a crimping terminal without using screws. All noise filters comply with the RoHS Directive.
