Power supply maker Cosel has entered the noise filter business with the introduction of five types of noise filters. Currently, as industrial equipment has been 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. Especially products that are exported to Europe must comply with strict EMC standards.
In order to comply with EMC, 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 applications. The products include:
* NAC series: High attenuator EMI filter at low wave frequency (single-phase AC input).
* NAM series: Low leakage current EMI filter (single-phase AC input).
* NAP series: External pulse high voltage attenuator EMS (electro-magnetic susceptibility) filter (single-phase AC input).
* TAC series: High attenuator EMI filter at low wave frequency (three-phase AC input).
* SNA series: Attenuator for ripple noise.
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.
