Main Features

Widely used in precision measuring instruments, building automation, precision machinery equipment, elevator lifting equipment, automation systems, calculator office equipment, servo system inverter equipment, frequency conversion equipment, lighting, information communication equipment, UPS switching power supply, automotive electronics On the equipment, after using high-quality imported components, the filtering effect is obvious!

EMI power filter function:
The power EMI filter is a reactive low-pass filter installed at the power inlet of the electronic device to suppress the noise interference transmitted through the power cable of the power grid and suppress the high-frequency interference signal generated by the electronic device itself. Enter the power grid and harm other electronic equipment. Therefore, EMI has become a device that must be installed in electronic equipment.
Power supply noise is a type of electromagnetic interference, and its conducted noise spectrum is approximately 10 kHz to 30 MHz, up to 150 MHz. Depending on the direction of propagation, power supply noise can be divided into two categories: one is external interference introduced from the power supply line, and the other is noise generated by the electronic device and conducted through the power cable. This indicates that the noise is a two-way interference signal, and the electronic device is both an object of noise interference and a noise source. According to the formation characteristics, noise interference is divided into two types: serial mode interference and common mode interference. Serial mode interference is the noise between two power cables (referred to as line-to-line). Common mode interference is the noise of two power cables to the ground (referred to as line to ground). Therefore, the electromagnetic interference filter should meet the requirements of electromagnetic compatibility (EMC), and must also be a two-way RF filter. On the one hand, it should filter out the external electromagnetic interference introduced from the AC power cable, on the other hand, it can avoid the device itself. External noise is emitted to avoid affecting the normal operation of other electronic devices in the same electromagnetic environment. In addition, the EMI filter suppresses both serial mode and common mode interference.

The selection of the EMI filter should consider its operating voltage, operating current, and withstand voltage.
The EMI filter should be installed at the power inlet to reduce radiated interference.
It is better to use a double glue line for the EMI filter connection line, which can eliminate some high frequency interference signals.
The input and output lines of the EMI filter should not be paralleled. It is necessary to open a certain distance to ensure the function of the filter.
The E point of the EMI filter and the chassis must be in good contact and grounded.
