Power relays are a versatile and important group of electrical devices used to facilitate the control of various circuits. In particular, they are used to control circuits when power is normally “off” and only switched “on” when a certain condition is met, such as a set temperature, pressure, or time. The ALE73F18 power relay is one of the most reliable and robust power relays on the market and offers excellent performance and durability. In this article, we will discuss the application field and working principle of the ALE73F18 power relay.

The ALE73F18 power relay is primarily used for operations that require reliable long-term switching and/or fast response time. It is designed to be used in applications where low power is expected or where the load is expected to be highly inductive. With its high contact rating of over 2 Amps, the ALE73F18 features excellent switching performance, even at high temperatures and when switching heavy loads. Additionally, it features a short arc distance which helps to ensure that the contacts are held in place under high shock and vibration. The ALE73F18 is also designed to dissipate heat quickly, thus helping to prevent damage and potential failure.

The ALE73F18 is available in a variety of voltage levels and power ratings, and is suitable for use in many applications, including industrial, HVAC, automotive, and other equipment that need to be controlled accurately and with reliability. In addition to the high contact rating, the ALE73F18 also features a variety of other features, such as a built-in surge protector, high isolation capability, mechanical life expectancy of 1,000,000 operations, and electromagnetic noise immunity.

The working principle of the ALE73F18 is relatively simple. The power relay features a secure seal-in type switch contact that is held in position using an internal coil. When the coil is energized, it creates a magnetic field which forces the switch contact to “seal-in” the switch position, thus ensuring that the circuit is switched “on” or “off” as required. The ALE73F18 also features a trip-proof design which prevents the internal contact from being damaged by high operating temperatures, electrical surge, or external vibration.

In addition to the high switching performance, the ALE73F18 features a number of other useful safety features. Its LED indicator gives the user a visual indication of the status of the switch, and it also features an optional mechanical contact that can help prevent accidental switching. The ALE73F18 also features a self-reset feature which allows the user to reset the switch by removing the power.

The ALE73F18 power relay is an ideal choice for applications that need reliable and long-term switching performance. It is highly reliable and robust, offers excellent performance and durability, and features various safety features to ensure that the switch operates correctly and safely. With its high contact rating of over 2 Amp, it is ideally suited for use in a wide range of applications and is an effective solution for control of large inductive loads.
