NAP-16-331-D Filters

Power Line Filter modules are electronic devices which commonly use in power systems to reduce unwanted noise and interference present from power supply. The product NAP-16-331-D is one of the common filter modules which widely used for its characteristics and applications in power line systems.

The NAP-16-331-D is an EMI filter module with a feed-through type designed for the medium power range (<200A). It is formed with a combination of inductors and metal-oxide varistors in parallel connection with the hot and neutral lines. The combination produces a common mode filter. The product can be used for a wide range of applications such as household appliances, various types of industrial machines, or even for medical electronics.

The working principle of NAP-16-331-D is based on the interaction between several components. First, the parallel connected metal-oxide varistors provide over-voltage protection for the hot and neutral lines. In addition to the voltage protection, the inductors play a role in filtering out the unwanted noises coming to the power line. With the dead time defined by the product specifications, these two components will form a low-pass filter which prevent the unwanted noise coming to the power line.

Moreover, NAP-16-331-D is equipped with a shield which able to reduce the amount of noise coming from the other sides. This shield, which also known as the EMI shield, helps reduce the electromagnetic interference coming to the power line. Furthermore, the shield also improves the safety for the user since it helps prevent the shock coming from the power line.

Finally, NAP-16-331-D can be used in a wide range of temperature conditions as well. The temperature range for the product is from -40 to +85°C. This feature makes the product suitable for applications which requires stability in temperature-sensitive conditions. Overall, the NAP-16-331-D is an all-round power line filter modules which suitable for a wide range of applications.
