Power Entry Connectors – Inlets, Outlets, Modules, encompasses a broad category of electrical components installed in medical equipment, appliances, industrial machinery, and other electronic devices. They are used to safely and quickly create an electrical connection between the device wiring and the main power supply. 5130.2000 is a standard for power entry connectors developed by the International Electrotechnical Commission (IEC). This article will explain the application field and working principle of 5130.2000.

Application field

The IEC 5130.2000 standard applies to a variety of power entry connectors, including inlets, outlets, and modules. Power entry inlets are used for securely connecting AC and DC power supplies to medical equipment, appliances, and industrial machinery. Power entry outlets are used to provide an external connection, either for system maintenance or an emergency power supply. Power entry modules are the combination of a power inlet, an integrated safety switch, and breakers or fuses for disconnection and protection purposes.

The standard includes general requirements for electrical, mechanical, thermodynamic, and environmental performance of power entry connectors. It contains performance requirements such as contact resistance, dielectric properties, and temperature resistance. Other requirements include strength testing, wear resistance, and water ingress protection in the case of outdoor applications.

Working Principle

The IEC 5130.2000 standard defines the operational, mechanical, and safety principles of power entry connectors. It also specifies general performance requirements for AC, DC, and electro-mechanical components.

Power entry connectors are typically rated by current load and voltage requirements. The correct rating should always be selected to ensure safe operation of the equipment. The current rating is determined by the type of application, location, and ambient temperature of the installation. A higher current rating should be selected if the equipment is located in an environment with high temperatures or a hazardous location. The voltage rating of a power connector should be at least equal to the highest voltage source to guarantee proper operation.

The IEC 5130.2000 standard requires power entry connectors to be of approved construction type, including single-pole and double-pole configurations. It also includes special conditions for non-standard power entry connectors, such as industrial plug-and-socket systems, and multi-pole connectors for applications involving current higher than 200A.

In terms of safety, the IEC 5130.2000 standard requires power entry connectors to meet requirements such as overload protection, earthing, and circuit protection. Overload protection is provided through the use of fuses or breakers, which must be appropriate for the current rating of the connector. Earthing is usually achieved through the use of earth conductors and is essential for safe operation. Circuit protection needs to be provided by the use of circuit breakers or fuses, which must be able to detect faults such as short circuits.

The IEC 5130.2000 standard also requires power entry connectors to meet environmental performance requirements, such as water-tightness and corrosion-resistance. This ensures reliability and longevity of the connector. Additionally, the standard requires connectors to meet requirements for immunity to radiated electromagnetic fields, which is essential for medical and industrial applications.

In conclusion, the IEC 5130.2000 standard is a comprehensive document that provides requirements for the performance, safety, and environmental requirements for power entry connectors. It ensures the reliability and longevity of the connector, as well as ensuring proper protection of the device and safe operation. Selecting the correct rated connector is essential to ensure safe operation of the equipment and to ensure it meets all the requirements of the standard.
