Visit store Items for sale About us Product Details Product features: Two-stage filtering, so the effect of filtering noise is better This module with decoder use or amplifier use, can filter the power supply high frequency noise Can achieve the elimination of utility interference, purify the power supply, can significantly improve the sound quality of the amplifier, improve the resolution and make the background quiet. The main role is to eliminate differential mode interference, capacity range 0.01UF --- 0.47UF 2A, 4A, 10A, 18A 4 kinds of specifications can be selected, easy to use, easy to operate, connect to use Product parameters: Name: Secondary common mode EMI power filter Input voltage: single-phase DC 110--250V Output voltage: single-phase DC 110--250V Load rated current: 2A, 4A, 10A, 18A 4 kinds of specifications can be selected Input port: 3-wire 7.62 socket input Output port: 2-wire 7.62 socket output Product Description: Two-stage composite EMI filter internal circuit, because of the use of two-stage (also known as two-section) filtering, so the filtering of noise better. For some users there is a repeat frequency of several kilohertz fast transient group pulse interference problems, can play a suppression role. This module with decoder use or amplifier use, can filter the power supply high-frequency noise, eliminate the mains interference, purify the power supply, can significantly improve the amplifier sound quality, enhance the resolution and make the background quiet. The input GND needs to be connected to the ground of the power line, but also can be connected to the chassis shell, depending on the specific circumstances, welding common mode inductor, please pay attention to the direction, please install the welding as indicated on the circuit board and baby pictures. High-frequency electromagnetic interference EMI filter common sense: For high-frequency electromagnetic interference (EMI), generally three technologies can be power filtering, can suppress interference noise, in actual use, often a mixture of two of them, or even a variety of technologies. They are: Power supply between the fire wire and zero line to add capacitance, that is, X capacitor. Choose X2 type, the main role is to eliminate differential mode interference, capacity range 0.01UF --- 0.47UF. Add capacitor between power line and ground line, i.e. Y capacitor. Y2 type is selected, mainly to eliminate common mode interference, capacity range is 2200pF ~ 0.1μF. To reduce leakage current, the capacity should not exceed 0.1μF, 3300PF is selected for this circuit board. Common mode suppression, common mode inductor (two power lines on the suppression coil), when the rated current is larger, the common mode choke wire diameter should also be increased accordingly, so that it can withstand the larger current. In addition, the appropriate increase in inductance, can improve the low frequency attenuation characteristics, the line using 10MH.
