ALE74B24

Power relays are an important component in the power generation and transmission process. They are used to control and transfer power between different sources of energy, such as electricity, diesel, gas, or steam. The ALE74B24 is a power relay specifically designed for applications that require must greater than 2 Amps of current.

Construction of ALE74B24

The ALE74B24 is a four-pole power relay with three-level coiling for higher current. It has a frame size of 11mm x 58.4mm, and its pole width is 7mm. The contacts are gold-plated silver, and the rated contact load is 6 to 8 Amps. The relay operates at a voltage of 250VAC or 350VDC.

Application Field and Working Principle

The ALE74B24 has a wide range of applications in the power generation and transmission industry. It is widely used for the control of power exchange between different sources, such as direct-current, alternating-current and mixed-frequency power. It works by switching closed and open circuits using an electromagnet-driven armature.

The ALE74B24 has a low activation power requirement of 0.14-0.19W. This ensures the power consumption is low and makes it suitable for energy efficient designs. It also has an operating temperature ranging from -40°C to +80°C. Its quick response time allows it to switch quickly, which is important for high current applications.

The ALE74B24 is designed for high performance and reliability. It has high contact resistance and low coil power rating that make it durable and suitable for long-term use. It is RoHS compliant and can also be modified for increased safety. This makes it suitable for high current and voltage applications, such as HVAC and power transmission.

Conclusion

The ALE74B24 is a high-performance power relay designed for applications requiring more than 2 Amps of current. It is RoHS compliant and has quick response time for high current applications. Its gold-plated contacts and three-level coiling ensure high reliability and long-term use.
