Power Line Filter Modules

Power line filter modules are specialized electronic components that are designed to reduce noise or interference electronically generated in electrical circuits. This noise could be in the form of rectified signals, electromagnetic interference (EMI), radio frequency interference (RFI) or AC voltage fluctuations. Power line filters are also seen as an integral component in any electronic system which eliminates any electrical noise and maintains the integrity of signal transmission. One of the most widely used power line filter modules is the RSMN-2003D.

RSMN-2003D Application Field

The RSMN-2003D is a rectangular shaped power line filter module designed for single phase electronic applications. It’s a noise attenuator that prevents interference from outside sources from entering into a circuit. It’s been used in a variety of applications such as medical equipment, switched mode power supplies, computers, test and lab instrumentation, high performance audio amplifiers, and telecommunications. It’s also an excellent choice of filter for applications where EMI/RFI and high transient voltage spikes must be effectively eliminated.

RSMN-2003D Working Principle

The RSMN-2003D features an integrated attenuator network which helps to reduce emitted noise from within the circuit, while simultaneously suppressing the incoming noise. It works by creating a wide range of low impedances within the circuit which effectively attenuates the high frequency interference. The RSMN-2003D also uses ferrite cores for maximum efficiency and suppression capabilities. Each core has iron powder within it which provides a higher attenuation level compared to other ceramic material alternatives. This ensures that EMI/RFI is effectively prevented from entering the protected circuits while simultaneously minimizing losses.

In addition, the RSMN-2003D is also equipped with a transient voltage spike protection feature that blocks any potentially damaging over-voltages that could otherwise damage sensitive components. It also features an in-built two-wire sensor that triggers an alarm when a current limit is exceeded. This ensures that the power line filter module can react in time to protect the system from any over current.

The RSMN-2003D also has an attractive operational temperature range of 0 to 70°C, making it an ideal choice for a variety of harsh environment electronic device applications. It’s also an UL recognized and CE compliant power line filter module, making it a reliable choice for most electronics professionals.

Conclusion

In summary, power line filter modules such as the RSMN-2003D provide an effective solution for eliminating EMI/RFI and transient voltage spikes. Its effective suppression and protection features allow it to be widely used in a wide range of applications. In addition, its attractive operational temperature range, UL recognized and CE compliant features make it a reliable choice for most electronics professionals.
