Store Categories Store Categories Other Product View Details Features: 1.Very suitable for DIY enthusiasts, with optional finished boards/DIY loose parts 2.The product is made of high-quality materials with guaranteed quality 3.The product has stable performance, convenient use, simple operation, and can be connected easily 4.EMI Line filter, which is also a high fidelity audio amplifier with high current electromagnetic interference 5.This module, when used in conjunction with a decoder or power amplifier, can filter the DC component of the power supply, eliminate and suppress transformer buzzing, high-frequency noise in the power supply, purify the power supply, significantly improve the sound quality of the power amplifier, enhance resolution, and make the background quiet Parameters: Name: three-level audio power amplifier EMI Line filter Input voltage: single-phase AC 110-250V Output voltage: single-phase AC 110-250V Rated current of load: 4A-20A Input port: Three wire 7.62 socket input Output port: 2-wire 7.62 socket output Module design features: 1.First level differential mode filtering, two differential inductors, for differential mode filtering of AC power supply to suppress mid to high frequency interference 2.First level common mode filtering, combining x2 capacitors and common mode inductors to form common mode filtering 3.Three stage common mode filtering, due to the use of two-stage (also known as two-stage) filtering, the effect of filtering noise is better. It can effectively suppress the problem of fast transient group pulse interference with a repetition frequency of several thousand hertz in certain user sites Main parts selection: X2 capacitor: 0.22UF 3PCS Y2 capacitor: 275V 3300PF 2PCS Differential mode inductance: 47UH 2PCS Common mode inductance: 2PCS Resistance: 1PCS Socket: 7.62 2PIN, 3PIN, 1 PCS each The three-level composite (1-level differential mode+2-level common mode) EMI electromagnetic interference filter circuit, due to the use of three-level (also known as three-level) filtering, has a better filtering effect on noise. It can effectively suppress the problem of rapid transient group pulse interference with a repetition frequency of several thousand hertz in certain user sites. This module, when used in conjunction with a decoder or power amplifier, can filter the DC component of the power supply, eliminate and suppress transformer buzzing, high-frequency noise in the power supply, purify the power supply, significantly improve the sound quality of the power amplifier, enhance resolution, and make the background quiet. The input GND needs to be connected to the ground wire of the power cord, and can also be connected to the chassis casing, depending on the specific situation.
