< :Two-stage CB board mounted AC filter
Product features:
◆>
Can effectively suppress the conduction of electromagnetic interference () along the power line, is bidirectionally reversible, and can effectively protect equipment from Electromagnetic interference from the power grid, and can prevent equipment from emitting electromagnetic noise to the power grid. It is conventional and versatile, cost-effective, compact and easy to install
◆>
Single-phase double-section series, two-stage common mode filter circuit, Good electromagnetic interference suppression characteristics
◆>
The internal nodes maintain a relatively stable impedance, with less dependence on the impedance of the source and load, and the filtering performance is stable
◆>
Effectively suppresses continuous or intermittent pulse interference
◆ Rated operating current>,
Can withstand> - times instantaneous overcurrent, used for power electronic equipment below power.
◆>
Routine and universal, cost-effective, compact structure, direct plug-in, CB board installation.
Usage occasions:
◆>
Used in most digital equipment to suppress continuous or intermittent pulse interference
◆>
Used in situations where transient interference exists and Electronic equipment that is required to pass B-level and level electromagnetic compatibility tests, especially has a significant interference suppression effect on communication equipment, power monitoring, fire alarms, and micro-control systems composed of various microcontrollers, C, and gate arrays.

Installation tips:
Installation location: The best location for filter installation should be at the entrance of the power cord to shorten the length of the input line in the chassis and reduce radiation interference Space coupling
Grounding: The grounding of the filter must be good. For filters with metal shells, the shell must be connected to the equipment chassis with low impedance, that is, the shell must be in conductive contact with the chassis panel and connected to the ground wire
Wiring of the input and output ends of the filter: input line of the filter , The output lines must be kept apart, and avoid running parallel lines to avoid coupling between the input cable and the output cable and bypassing the filter, causing the filter to fail.
