Power entry connectors are a type of electrical connector typically used to supply power to electronic equipment. The FN389B-2-21 is a power entry connector which can be used for a variety of different applications. This article will discuss the FN389B-2-21, its application field and working principle.

The FN389B-2-21 is an IEC inlet module which is typically used to supply power to electronic appliances. It is equipped with an integrated fuse holder which allows the user to easily install and replace fuses to protect against electrical failure or overload. The gasketed housing of the FN389B-2-21 improves its protection against dust and other environmental contaminants. The connector has a 3-pole AC power inlet with earthing, and an additional 3-pole AC outlet. It is approved for industrial use in safety applications, and is rated for operation at an AC voltage of 250V and a frequency of 50/60 Hz. The rated current of the connector is 16A.

The FN389B-2-21 can be used in a variety of different applications, such as in telecommunication, medical and industrial equipment, computers and peripherals, household appliances, power tools, and lighting. It is especially suited for applications where space is limited due to its compact size. The FN389B-2-21 is also widely used in the automotive industry, where it is often found in dashboards, footwells, and other interior components.

The working principle of the FN389B-2-21 is based on the principle of electromagnetic induction. When an AC voltage is applied to the power inlet, an electro-magnetic field is generated. The current generated by this field is then routed throughout the device, thereby supplying the connected appliance with power. The integrated fuse holder helps to protect the device from electrical surges.

The FN389B-2-21 is designed for safety and reliability in a wide variety of applications. The connector meets the requirements of UL, CSA, and TUV, making it an ideal choice for applications that require compliance to safety standards. Its compact size, integration of an integrated fuse holder, and protection against environmental contaminants make it a great choice for many power entry connections.
