NAC-30-472

The NAC-30-472 is a COSEL NAC series single-phase EMI line filter rated at 30 A and about 250 V AC or 250 V DC, in a chassis-mount body with screw terminals and an optional DIN-rail fitting. It is the higher-current member of the NAC family, a general-purpose filter that attenuates the conducted noise on a mains or a DC line so a larger switching power supply and the equipment meet the emissions standard, and the 472 line-to-ground capacitor code gives a leakage current that a designer confirms against the safety limit. The filter combines common-mode and differential-mode elements to suppress the noise that a switching converter reflects onto the line, and the screw terminals and the DIN-rail option make the installation in a panel straightforward. The 30 A rating suits a higher-power supply such as the 600 W PBA or a multi-unit rack, and the NAC series covers a range of currents and capacitor codes, so a designer can match the current and the leakage to the application. Availability is confirmed per project. Typical applications include a higher-power switching supply input, an industrial control panel, a telecom rack and a test system. Every filter BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the current and the leakage code and plan the mounting.
