Product details
Product Details:
The circuit consists of two parts: the first part is a DC component filtering circuit, and the second part is a two-stage composite EMI filtering circuit.DC component filtering circuit: The first-level imitation of the British DC elimination circuit eliminates the interference of AC power caused by inverter air conditioners, electronic switching power supplies, refrigerators, chargers and other DC components in AC 220V mains. The DC elimination circuit built by diodes and capacitors eliminates and prevents the DC component in the mains AC power supply, and prevents the transformer from magnetic saturation or static current increase due to the DC component.The internal circuit of the two-stage compound EMI filter adopts two-stage (also known as two-section) filtering, so the effect of filtering noise is better. For some users, there is a problem of fast transient group pulse interference with a repetition frequency of several kilohertz, which can inhibit it.This module can be used with s or power amplifiers or other power supplies. It can filter the DC component of the power supply, high-frequency noise, eliminate interference from the mains, and purify the power supply. It can significantly improve the sound quality of the power amplifier, enhance the resolution and make the background quiet.The input GND needs to be connected to the ground wire of the power cord, and can be connected to the chais shell at the same time, depending on the specific situation.
Specifications:
PCB size: FR4 38X100X1.6MMThe shortest design of the high-current line, the short path, can withstand larger current, and has le interference to the outside world.2A 10MH common mode inductor filter. Load power 440W.4A 10MH common mode inductance filter, load power 880W.8A flat copper wire inductance, load power 1760W. (The diode current can only reach 8A, higher power can be achieved by replacing the high current diode)
