Power Relays, Over 2 Amps: 1393218-2 Application Field and Working Principle

Power relays used to be restricted to those relays that are built to exceed a 2 amp current carrying capacity. Today, however, there is much more to consider for a successful power relay in order to meet modern electrical safety requirements. The idea of a power relay is to enable higher levels of power to be switched and directed along a circuit, therefore providing line isolation and control of a power source.

The 1393218-2 power relay is a miniature, single-pole, dual-throw (SPDT) power relay that is designed to handle loads between 2 and 4 amps. It operates with an input voltage of up to 24 volts and is designed with both standard AC and DC applications. It is an extremely reliable product and offers the advantage of a long life expectancy.

The typical application of the 1393218-2 power relay includes motor control, lighting, machinery, communication systems, computers, and other ambient temperature control devices. Additionally, it is used in a variety of applications requiring switching and power control and isolation, such as electronic starters, remote control actuation, DC spark gap control, and AC switching systems.

Working Principle

The 1393218-2 power relay is designed to allow high currents to be controlled without exposing components to highvoltages. This is achieved through a series of well-thought-out internal construction features. At its core, it works by using an electromagnet to draw energy from a power supply and then using this energy to cause motion within the relay’s mechanism. In general, power relays allow high current to be sent through one end of the relay when a low voltage is connected to the other end.

In order for a power relay to work correctly, it must draw enough energy from the power supply to cause the electromagnet inside it to move. This electromagnet, in turn, acts upon the internal contacts inside the relay, causing them to close and open. The internal contacts of the relay are what allow the electricity to pass through, thus enabling the high current to flow through the relay.

The 1393218-2 power relay is a high-quality relay, and its superior quality is due to its use of high-quality electromagnets and other internal components. It is this quality that allows it to handle higher currents without suffering from fatigue due to excessive heat or vibration. Additionally, its construction increases its mechanical life while providing improved electrical safety, high switch contact reliability, and higher power capabilities.

Overall, the 1393218-2 power relay is designed for long-term use and is built to provide reliable performance in a wide variety of applications. Its SPDT construction allows it to handle large loads while its efficient design helps to reduce power loss and provide a higher level of control over the power supply.
