Features 3 STAGE: Adopting 1 stage differential mode and 2 stage common mode filtering, this EMI filter has a better noise filtering effect. GOOD SUPPRESS FUNCTION: This EMI power filter can suppress the problem of rapid transient group pulse interference with a repetition frequency of several thousand hertz in certain user sites. MULTI FUNCTION: This module, used with a decoder or power amplifier, can filter the DC component of power supply, eliminate and suppress high frequency noise in the transformer and power supply, improve sound quality of amplifier, enhance resolution, and EASY TO CONNECT: The input GND needs to be connected to the ground wire of the power cord and can also be connected to the chassis casing. RELIABLE COMPONENTS: This filtering board adopts excellent components, which ensures high reliability and stability in working. Specification: Item Type: EMI Filter Material: PCB Input Voltage: Single phase AC 110-250V Output Voltage: Single phase AC 110-250V Load Rated Current: 20A Input Port: 3 wire 7.62 socket input Output Port: 2 wire 7.62 socket output Design Features: 1. First stage differential mode filtering, two differential inductors perform differential mode filtering on the AC power supply to suppress mid to high frequency interference 2. Second stage common mode filtering, can combine into a common mode filter through X2 capacitors and common mode inductors 3. Three stage common mode filtering, due to the use of two stage filtering, the effect of filtering noise is better. It can effectively suppress the problem of rapid transient group pulse interference with a repetition frequency of several thousand hertz in certain user sites Package List:1 x EMI Filter Package List 1 x EMI Filter
