NS1535

Introduction

Power line filter modules are electronic devices used to reduce the levels of radio frequency (RF) interference present on AC mains power lines. The NS1535 is a specialized passive power line filter module based on a low pass filter design. It is rated for a maximum current of 10 amps and has an operating temperature range of -20°C to +85°C.

Application

The NS1535 is suitable for many applications where interference reduction is needed. It is commonly used in industrial machinery, electrical and electronic devices, household products, communication systems, power supplies, and even aircraft. Additionally, the NS1535 can be used in medical imaging systems and other medical equipment where power line noise must be reduced.

Benefits

The NS1535 offers several benefits including superior characteristic impedance, high power line rejection, and low leakage current. Additionally, NS1535 modules are designed to reduce line noise to enable equipment to comply with electromagnetic compatibility (EMC) regulations. This ensures that the power line filter performs as intended and the equipment being protected is not adversely affected by the presence of radio frequency interference.

Working Principle

The NS1535 utilizes a low pass filter circuit to reduce RF interference. This filter is composed of a capacitor and an inductor in a series circuit, with the inductor usually connected in parallel with a resistor. This forms a low pass filter which attenuates frequencies above a certain point, while allowing signals below this frequency to pass through undistorted. In the NS1535, the low pass filter is composed of an X-class capacitive-inductive filter network, allowing excellent attenuation of high-frequency and transient noise.

Design

The NS1535 is composed of a two-stage filter network. The first stage is a combination of an inductor and a capacitor, which form the low pass filter. The second stage is composed of two coils, which act as an impedance matching network and reduce the reflected current. This two-stage filter network allows the NS1535 to reduce power line noise while providing very low insertion loss.

Conclusion

The NS1535 power line filter module is a powerful solution that can help reduce interference on power lines. It is rated for a maximum current of 10 amps and has an operating temperature range of -20°C to +85°C. The NS1535 is suitable for many applications where interference reduction is required and offers several benefits including superior characteristic impedance, high power line rejection, and low leakage current. The filter is composed of a two-stage filter network which uses a combination of an inductor and a capacitor, and two coils to form a low pass filter and impedance matching network, respectively.
