2VR1 Power Line Filter Modules are especially designed to suppress the interference from various power sources and prevent interference and disruption of power supply in computers and other electronic devices. they are designed to echo suppression, low and high frequency rejection, electrostatic discharge (ESD) protection, turn-on surge protection, and line side protection.

2VR1 Power Line Filter Modules are installed at the power source or primary side of a power supply, where harmonic current and voltage factors can be minimized. These power line filters range in current rating from 0.2A to 6A, allowing for a variety of applications. In addition, these power line filters can be used in a wide range of AC applications including medical, industrial, outdoor, gaming and network communication applications.

The effectively working of 2VR1 Power Line Filter Modules depends on the effective suppression of the reflected impedance, harmonic counter pressures, resonance and various external factors of the power supply.Once these factors are effectively suppressed, the module works to protect the equipment from various external elements, such as EFT, surge, and noise.

The 2VR1 Power Line Filter Modules feature a 2-stage filter structure, including differential mode (DM) and common mode (CM) filter circuits. The DM circuits are made of a series inductor, a series capacitor, and a parallel capacitance. The CM circuits feature two inductors and a capacitor. The series inductors provide EMI suppression, while the capacitor reduces the voltage attenuation, thus improving the signal integrity. Both DM and CM filter circuits work together to ensure adequate EMI and RFI performance.

The 2VR1 Power Line Filter Modules feature a tri-buffer design to minimize the power line noise, which is caused by the power flow imbalance. The tri-buffer works by adjusting the power levels on each of the three circuits, thereby reducing the power line noise. Additionally, these modules feature a built-in overvoltage protection circuit, which is used to protect the devices from overvoltage damage.

The 2VR1 Power Line Filter Modules are used in a variety of AC applications such as medical, industrial, outdoor, gaming and network communication applications. The modules also provide added safety for the power lines, as they effectively reduce the amount of peak current that can be delivered to the equipment. Furthermore, the modules are designed for low-profile installation, ensuring easy integration into most existing applications.

The working principle behind the 2VR1 Power Line Filter Modules includes effective suppression of the reflected impedance, harmonic counter pressures, resonance, and other external signals impacting the power supply. This is accomplished with a combination of DM and CM filter circuits and the tri-buffer design. Additionally, an overvoltage protection circuit helps to reduce the risk of damage from overvoltage. All of these features combine to create a stable and reliable power source, which is necessary for efficient and reliable operation of electronic equipment.
