Features: The power supplys EMI filter is a reactance-type low-pass filter that is installed at the power supplys input of an electronic equipment. Power supplys filter can inhibit the noise transmitted through the grids power cable, and can inhibit the high frequency interference signal generated by the electronic equipment itself. EMI has become a important device in electronic equipment. High-quality component provide obvious filtering effects. Widely used for precisions measuring instruments, building automation, precisions machinery, elevators lifting equipment, automated system, calculator inverter office equipment, servo system inverter equipment, frequency conversion equipment, lighting equipment, information and communication equipment, UPS power supplys, automotive electronics, etc. Delivery only includes a EMI high frequency two-stage power low-pass filtering board for 25A power supplys.
