4750 Series, Power Entry Modules (PEM)

Power entry connectors encompass a range of components, including inlets, outlets, and modules, specifically engineered to handle power connections. These connectors are designed to accommodate the entry or exit of electrical power into or out of a device or system. One notable feature of power entry connectors is their ability to filter out unwanted frequency interference, such as electromagnetic interference (EMI) and radio frequency interference (RFI). These connectors incorporate filtering mechanisms that help reduce the impact of these interferences on the connected circuit, ensuring clean and stable power transmission. Often referred to as "heavy-duty" power connectors, some power entry connectors are capable of handling extremely high levels of amperage or voltage. These connectors are engineered with robust construction and enhanced electrical properties to safely manage the demanding power requirements of industrial or high-power applications. Power entry connectors come in various styles and standards, including International Electrotechnical Commission (IEC) and National Electrical Manufacturers Association (NEMA) standards. These standards define the specific dimensions, pin configurations, and performance characteristics of the connectors, ensuring compatibility and interoperability across different devices and systems. Furthermore, there are specialized power entry connectors designed for specific countries or regions, considering unique electrical standards and requirements. These connectors may incorporate country-specific plug and receptacle designs, enabling safe and reliable power connections in accordance with local regulations. Some power entry connectors feature additional functionalities, such as integrated circuit breakers or switches. These built-in components provide an added layer of protection by automatically disconnecting the power supply in the event of an overload or short circuit, helping to prevent damage to the connected equipment or system. Ingress protection (IP) levels are also considered in the design of power entry connectors. IP ratings indicate the degree of protection against the ingress of solid objects (dust, dirt) and liquids (water, oil) that the connector can withstand. Different IP ratings ensure that the connectors are suitable for specific environmental conditions, offering reliable performance and longevity even in harsh or demanding settings. In summary, power entry connectors play a crucial role in facilitating power connections while addressing specific requirements such as filtering unwanted frequency interference. They come in various styles, standards, and specialized variants for different countries, with some featuring circuit breakers, switches, and varying IP levels for added functionality and protection. These connectors are essential components in ensuring safe and efficient power transmission in a wide range of applications.
