Features:Power supply filter is a kind of reactance-type low-pass filter, installed at the power supply input of electronic equipment. It can inhibit noise transmitted through grid power cable, and can inhibit high-frequency interference signals generated by the electronic device itself. imported components provide obvious filtering effect. This product has become a must have device installed in electronic equipment. Widely used for precision measuring instruments, building automation, precision machinery, elevator lifting equipment, automated system, calculator inverter office equipment, servo system inverter equipment, frequency conversion equipment, lighting equipment, information and communication equipment, UPS power supply, automotive electronics, etc. Specifications: Module Filtering Categories:1-stage filteringModule Current: 6A; 25A (Optional)Weight: 38g(approx.) Note:The selection of filter should consider its working voltage, working current, withstand voltage. Filter should be installed at the inlet of power supply, to reduce radiation interference. It is better to choose twisted-pair cable as filter connection cable, which can eliminate some high-frequency interference signal. Filter input and output cable must not be parallel, keep them away from each other to a certain distance in order to ensure the function of filter. E point and case of filter must be in good contact, and connect to ground wire. Package Includes: 1 x Filter Board
