Electromagnetic Compatibility (EMC) refers to the ability of a device or system to function properly in its electromagnetic environment without generating excessive electromagnetic interference (EMI) that could disrupt the operation of other devices or systems. EMI can manifest in various forms, including conducted emissions (traveling along power lines) and radiated emissions (traveling through the air).
EMC filters play a crucial role in mitigating EMI by attenuating unwanted electrical noise at specific frequencies. They are typically installed at the point where an electrical line enters a device or system, acting as a barrier between the noisy source and the sensitive circuitry. By filtering out the noise, EMC filters help ensure the proper functioning of electronic equipment and prevent interference with other devices in the vicinity.
The RSHN series is a line of single-phase EMC filters designed for general-purpose applications. These compact and powerful filters offer superior performance in attenuating conducted EMI, making them ideal for protecting sensitive electronic equipment from unwanted noise.
Let’s learn more about them.
The RSHN 2020d: A Compact Powerhouse
At the forefront of EMC filter solutions is the RSHN-2020d, which is specifically engineered to address the challenges posed by EMC issues in single-phase electronic systems. Let’s dissect the key features of this remarkable filter.
Filter Type and Configuration
The RSHN-2020d belongs to the category of single-phase EMC filters, designed to handle the challenges posed by interference in systems powered by a single alternating current (AC) phase. Single-phase filters are particularly crucial in applications where the power supply is not three-phase, which is common in many residential and commercial setups.
The RSHN Series is configured as a two-stage filter. This design is advantageous as it provides enhanced filtering capabilities, tackling a broader range of frequencies. The first stage typically involves high-frequency noise, while the second focuses on lower frequencies. This dual-stage approach ensures a comprehensive solution to EMC challenges.
Voltage and Current Ratings
The RSHN Series is optimized for applications with a rated DC voltage of 250V and a rated AC voltage of 250V. These specifications make it suitable for a wide range of electronic setups operating within these voltage parameters. With a current rating of 20A, the RSHN Series exhibits robust performance capabilities, accommodating devices with varying power requirements.
Applications and Approvals
The versatility of the RSHN Series extends to its broad range of applications, making it a reliable choice for general-purpose electronic systems. Whether used in industrial machinery, medical equipment, or consumer electronics, the RSHN Series proves its mettle in ensuring EMC compliance and system reliability.
To underscore its credibility, the RSHN Series has received approvals from reputable agencies, including CSA (Canadian Standards Association), EN (European Norm), and UL (Underwriters Laboratories). These certifications highlight the compliance of the RSHN Series with rigorous safety and performance standards, instilling confidence in its reliability across diverse applications.
Operating Conditions and Mounting
Designed to withstand varying environmental conditions, the RSHN Series boasts an impressive operating temperature range of -25°C to 85°C. This wide temperature tolerance makes it suitable for deployment in a spectrum of climates and industrial settings, where temperature fluctuations are common.
The DIN Rail mounting type of the RSHN Series further enhances its adaptability. DIN Rail mounting is a standard method for installing industrial control and automation components on a standardized mounting rail. This type of mounting facilitates easy integration into existing setups and ensures a secure and space-efficient installation.
Termination Style
The RSHN Series features a terminal block termination style. Terminal blocks are essential in creating secure and reliable electrical connections. The use of terminal blocks in the RSHN Series enhances ease of installation and maintenance, allowing for a secure and organized termination of electrical connections.
