Power Line Filter Modules are a type of electronic filter designed to protect sensitive equipment from electromagnetic interference (EMI). They are especially useful in industrial and other applications where multiple line signals and noise are present. The NBH-20-681 is a power Line Filter Module designed to reduce the noise and interference from electrical and electronic devices in industrial and telecom applications.

The NBH-20-681 has two main parts, the filtering section and the control section. The filtering section is composed of a series of capacitors, inductors, and resistors housed in a metal enclosure. The capacitors are connected in parallel to form a low-pass filter, while the inductors and resistors form a high-pass filter. This combination of filters is designed to minimize the amount of noise and interference that are carried on the power line.

The control section consists of three main components, a power supply, a voltage regulator, and an isolator. The power supply supplies power to the module’s circuitry, while the voltage regulator maintains a consistent voltage level from the power supply. The isolator keeps the circuitry separated from the power line to ensure that any interference on the line is filtered out. This allows the NBH-20-681 to provide a low noise level when powering any device in its vicinity.

The NBH-20-681 also includes a transient suppression circuit which prevents ultra-high frequency signals from causing overloads or outages. This makes it the ideal filter for industrial and telecom applications where high reliability is sought. Additionally, the module features wide frequency range and low insertion loss, making it ideal for applications up to 40 kHz.

The NBH-20-681 can be used with various power sources including AC or DC power. When it is connected to AC power, the product features two main functions; line filtering and surge protection. It filters out high frequency, common mode, and differential mode EMI, ensuring that no interference from outside sources is transmitted to the device being powered. Additionally, it helps protect against voltage spikes that can occur during operation.

When connected to DC power, the NBH-20-681 helps protect against both differential and common mode voltage noise. It also improves the stability of any DC power distribution system by helping to minimize the negative effect of power outages and voltage variations. The module also has a low power consumption, which helps make it particularly cost effective.

The NBH-20-681 is an excellent choice for power line filter modules, and it is particularly useful for applications where reliability and performance are important. It’s wide frequency range, low insertion loss, and transient suppression circuitry make it an ideal choice for industrial and telecom applications. Additionally, its ability to filter out EMI, combined with its low power consumption, make it a dependable and affordable option for any power line filter needs.
