AC110-250V 2A 4A 10A 20A differential mode / common mode EMI Power Filter Board

 
Product Features:
1. Two-stage compound EMI filter, so the noise filtering effect is better. 2.
2. Shortest design of high current line, short path, can withstand more current, less interference to the outside world. 3.
3. Can achieve the elimination of mains interference, purify the power supply, can significantly improve the sound quality of the amplifier, improve the resolution and make the background quiet.
4. The main role is to eliminate differential mode interference, capacity range 0.01UF --- 0.47UF.
5.2A, 4A, 10A, 20A 4 specifications are available, easy to use, simple to operate, just connect and use.
Product Parameters:
Name: Differential mode + common mode composite high efficiency EMI power filter
Input voltage: Single phase AC 110--250V
Load rated current: 2A - 20A
Input port: 3-wire 7.62 socket input
Output port: 2-wire 7.62 socket output
Note:
2A and 4A filters with 5A fuse as standard, 10A and 20A filters with 20A fuse as standard. This module can be used with decoders or amplifiers to filter high frequency noise from the power supply, eliminate mains interference, purify the power supply, significantly improve the sound quality of the amplifier, enhance the resolution and make the background quiet. The input GND needs to be connected to the ground of the power line, and can also be connected to the chassis shell again.
High-frequency electromagnetic interference EMI filter common sense: for high-frequency electromagnetic interference ( EMI), the general three techniques can be power supply filtering, can suppress interference noise, in practice, often a mixture of two of them, or even a variety of techniques. They are: 1. power supply between the fire wire and zero line to add capacitance, that is, X capacitor. The main function is to eliminate common mode interference, with a capacity range of 0.01UF - 0.47UF. 2.The capacitor is added between the power line and the ground line, i.e. the Y capacitor. The main function is to eliminate series interference, the capacity range is 2200pF～0.1μF. In order to reduce leakage current, the capacitance should not exceed 0.1μF, this board choose 3300PF. 3. common mode suppression, common mode inductor (two power lines on the suppression coil), when the rated current is larger, common mode choke wire diameter should be increased accordingly, in order to be able to withstand the larger current. In addition, an appropriate increase in inductance can improve the low frequency attenuation characteristics.4. Differential touch suppression, differential touch inductance, suppressing series mode interference between power lines.
