Feature: 1. [Suppression of Interference] EMI filter board installed in the power inlet of electronic equipment, can suppress the noise interference transmitted in through the power lines of the power grid. 2. [Multi Function] This EMI filter module can also suppress the high frequency interference signals generated by the electronic equipment itself into the grid, interference with other electronic equipment. 3. [Use Requirements] Power filter board should meet the requirements of electromagnetic compatibility, must also be bidirectional RF. To filter out external EMI, but also to avoid their own noise interference to the outside. 4. [Professional] Sound power EMI filter module for series mode and common mode interference are suppressed. Do not affect the normal operation of other electronic equipment in the same electromagnetic environment. 5. [Stable And Practical] Power filter using premium materials, is a kind of reactance low pass filter, filtering effect is obvious, stable performance, suitable for accuracy measuring instruments, automation systems, etc. Specification: Item Type: EMI Filter Board Material: PCB Current: 20A Widely Used: For Accuracy Measuring Instruments, Building Automation, Accuracy Mechanical Equipment, Elevators, Lifting Equipment, Automation Systems, Calculators, Office Equipment, Servo System Inverter Equipment, Frequency Conversion Equipment, Lighting, Information and Communication Equipment, UPS Switch Power Supply, Automotive Electronics and Other Equipment. Package List: 1 x EMI Filter Board Note: 1. EMI filter selection should consider its working voltage, working current, voltage withstand value.2. Should be installed in the power supply entrance location to reduce radiation interference.3. Connection wire selection of double rubber wire is better, it can eliminate part of the high frequency interference signal.4. Input and output wires should not be parallel, need to pull away a certain distance to ensure the function of the filter.5. EMI filter E point and chassis shell must be in stable contact, and connected to the ground wire.
