20A AC Power Filter DC Block Filtering DC Component Audio Isolation Overvoltage Surge Protection F/ Transformer Electrical Front

20A AC Power Filter DC Block Filtering DC Component Audio Isolation Overvoltage Surge Protection use Transformer electrical appliance frontDescription:Notice: High voltage danger, beware of electric shock!Eliminate the interference of DC components from AC 110V-220V home appliances such as frequency-converted air conditioning, electronic switching power supply, refrigerator, charger etc. Using diodes and capacitors to build a DC elimination circuit, the DC component in the mains AC power supply is eliminated and blocked, preventing the transformer from magnetic saturation or static current increase due to the DC component.This module is used in conjunction with a decoder or power amplifier to filter the DC component of the power supply, eliminate and suppress the hum of the transformer, the high-frequency noise in the power supply, purify the power supply, and can significantly improve the sound quality of the power amplifier, enhance the resolution and make the background quiet.Features:Input Voltage: AC 110V-220VOutput Voltage: AC 110V-220VWorking Current: 20AFunction: 1> Eliminate the DC voltage component of the AC power supply.               2> Surge protection, overvoltage protection.Board Size: 105x48x26mm(LWH)Weight: about 100g
