EAP-03-102-D

Power Line Filter Modules refer to electronic components that connect to the power supply and manipulate the flow of electricity to create an ideal power environment for electronic circuits, devices, and systems. Filter modules can be used to reduce the effect of electromagnetic interference (EMI) from external power sources to improve the quality of power signals, but they can also be used to improve the power factor of a given system. EAP-03-102-D, in particular, is a type of AC power line EMI filter module that is designed and manufactured by Shenzhen Hopelight Technology Co., Ltd., and it has a wide range of applications.

Applications: EAP-03-102-D power line filter module is ideal for applications such as solid-state lighting and power supplies, musical instruments, and home appliances because it can help reduce conducted Electromagnetic Interference (EMI) on the power lines of these devices. It also has the ability to reduce switching noise on AC power line to ensure optimal performance of applications. Additionally, it can be used in areas where high-power loads are expected, such as solar photovoltaic systems and systems with high power drives.

Working Principles: EAP-03-102-D filter module works on the concept of “Common-Mode Interference”, where current or potential difference occurs across two separate conductive paths. This filter consists of two capacitors connected in series on the power line to divert any unwanted electromagnetic noise to ground. The filter is designed with a high-impedance for noise commonly found in the 50-250 MHz frequency range. When the electric interference exceeds this range, the filter will act to reduce the effect of the interference by providing a path of least impedance, thereby resulting in improved power quality.

The filter module also consists of four diodes, which are connected to the filter\'s input and output sides to form two RC networks that act as low-pass filters. The diodes help limit the high-frequency noise by providing a shunt path for them to the ground. In addition, an inductance coil is included in the filter module to improve the filtering effect and extend the response time of the filter.

Moreover, an electrolytic capacitor is incorporated in the module to store electrical current for when the current flow is inadequate. This ensures that the filter module can provide the necessary power even in the event of temporary power failure. In addition, the capacitor is connected to the filter\'s input and output sides to act as a ground loop isolator, which further improves the performance of the filter.

EAP-03-102-D power line filter module is designed with several interesting features that allow it to provide superior filtering quality and enhanced power reliability. The wide range of applications and excellent performance make it a great choice for use in a variety of systems and applications. With its ability to provide effective filtering and improve power quality, it is no wonder why this power line filter module is so popular among manufacturers and developers.
