The Power Line Filter Modules, represented by 4EXP, is a component utilized to provide AC/DC power supply or EMC/EMI filtering. It is designed to optimize the response of accelerating components, providing a more efficient and reliable response. This type of filter effectively reduces the disturbances generated by the load at the input voltage of the electronic devices. It also eliminates the need of fitment of additional filters for the wave form components.

4EXP Application Field and Working Principle

4EXP is intended for application in the industrial automation and control. It is applicable in areas such as industrial control systems, power systems, motor drives, motor control systems, lighting systems, and home appliances. 4EXP is a bypass-type filter having the capacity to filter power line components. The filter consists of two capacitors- one on each line, and a resistor-inductor network connected between the lines. It can limit the high-frequency noise at its specified frequency without affecting the normal waveforms.

The working principle of 4EXP is based on two types of active components. The first type is the voltage-dependent resistor (VDR) or resistor-capacitor (RC) network, which creates a voltage and frequency filtering effect. The second type is the isolation transformer. This type of transformer allows for a high degree of EMC/EMI filtering, and eliminates power line disturbances. It works by converting the AC current entering the filtering unit into a low-current, low-frequency DC signal. This signal is then routed through capacitors to the output of the filter, resulting in a much reduced noise level.

The 4EXP filter is designed to reduce noise, harmonics and disturbance at the power line level. This is accomplished by applying specific frequency filters, which block the frequencies that can cause interference or damage to your equipment. The principal benefit of the 4EXP filter compared to other power line filter modules is its low-noise performance. The 4EXP filter’s low-noise, wide-band rejection characteristic makes it suitable for a wide range of applications, ranging from audio/video equipment to industrial control systems.

4EXP is designed to provide a relatively low cost, low-impedance, high-efficiency AC/DC power supply or EMC/EMI filter solution. It is suitable for a wide range of applications from industrial to consumer electronics. It is designed to reject EMI signals in the frequency range of 5kHz to 1MHz, while allowing the waveforms to pass through without disruption.

4EXP is a reliable and cost-effective solution for power line filtering. Its high-quality components and advanced design offer superior performance for noise, harmonics, and disturbance rejection. Its small form factor, low profile, and ease of installation make it an ideal choice for use in industrial and consumer applications. 4EXP provides a cost-effective, high-efficiency component for reducing EMI and unwanted power line disturbances.
