Features Application: Filters are widely used in precision measuring instruments, building automation, precise machinery, elevator lifting equipment, automation systems, calculator frequency conversion office equipment, servo system frequency conversion equipment, frequency conversion equipment, lighting equipment, information communication equipment, UPS power supply, automobiles electronics etc. Obvious Filtering Effect: EMI power filter adopts selected electronic components, has a precise manufacturing process, and has an obvious filtering effect. Suppression of High-Frequency Interference Signals: The power filter can suppress the noise transmitted through the power cable of the grid, and can suppress the high-frequency interference signals generated by the electronic equipment itself. Reactive Low-Pass Filter: The power supply EMI filter is a reactive low-pass filter installed at the power input of electronic equipment. Ideal Accessories: Two-stage EMI filters have become must-installed equipment in electronic equipment and are very practical electronic accessories. Features: 1.Power supply EMI filter is a kind of reactance-type low-pass filter, installed at the power supply input of electronic equipment. 2.It can inhibit noise transmitted through grid power cable, and can inhibit high-frequency interference signals generated by the electronic device itself. 3.High quality imported components provide obvious filtering effect. 4.EMI has become a must have device installed in electronic equipment. Specifications: Module Filtering Categories: 2-stage filtering Module Current: 6A; 25A (Optional) Length: 9.5cm/3.7in Weight: 50g(approx.) Note: 1.The selection of EMI filter should consider its working voltage, working current, withstand voltage. 2.EMI filter should be installed at the inlet of power supply, to reduce radiation interference. 3.It is better to choose twisted-pair cable as EMI filter connection cable, which can eliminate some high-frequency interference signal. 4.EMI 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. 5.E point and case of EMI filter must be in good contact, and connect to ground wire.
