Power line filter modules are widely used in various fields, and the 15VT6 module is no exception. Comparing with its predecessors, this module offers a better cost-performance, making it a popular choice amongst consumers. The application field and working principle of the 15VT6 are discussed here.

Application Field

The 15VT6 module is mainly used at various power outlets, such as residential or commercial buildings, offices, server rooms and the like. For home users, it is usually connected between the wall socket and the electronic device in order to reduce electromagnetic interference (EMI) and line noise caused by AC mains. As for commercial/industrial applications, it is used to reduce the potential difference between two points which could cause potential hazards and interference interference.

Working Principle

The working principle of the 15VT6 module is to capture EMI and incoming line noise, as well as to reduce potential differences. It utilizes the multiple layers of varying-thickness metallic or carbon plates to make the necessary adjustments. These plates are connected to the ground sockets and form a passive filter to filter out unwanted frequencies. The 15VT6 module then uses capacitors, coils and resistors to form a four-pole LC filter circuit. One of the coil ends is connected to the ground input, and the capacitor is connected between the coil and the line input. This forms a balanced LC filter circuit that can reduce the amplitude of any incoming frequency.

The 15VT6 also has a stage of EMI suppression, which helps better reduce and enlarge the filter frequencies. This is achieved through the parallel combination of a varistor and a choke coil. The varistor will provide surge and transient voltage protection, while the choke coil limits any EFT or ESD noise. The choke coil and the varistor are connected to the power feedback line, which has been connected to the ground previously.

In conclusion, the 15VT6 module is highly capable of providing protection against EMI and line noise interference. Its multiple layers of varying-thickness plates, combined with the LC filter circuit and EMI suppression stage, ensure that all incoming frequencies are reduced to a safe level. It is also relatively easy to install and maintain, making it a popular choice for residential and industrial applications.
