EHU2-12

EHU2-12 is an accessory designed for pumps and motors primarily used in industrial applications. It comes with two separate circuits that can work together to provide a wide variety of applications. The EHU2-12 is commonly used to provide a solution for controlling the speed of the motor and pump while also providing overload protection and other features.

Application Field

The EHU2-12 is mainly used in industrial settings, including but not limited to agriculture, construction, manufacturing, mining, and warehousing. In these areas, the EHU2-12 provides an efficient solution for controlling the speed of pump, motor, blowers, fans, and more. This makes it ideal for controlling the flow of liquids, gases, and other materials through employed systems. Additionally, this accessory is designed with circuitry for overload protection, ensuring proper safety of the equipment and its users.

Working Principle

The EHU2-12 has two circuits. The main circuit is a contactor and a pump motor starter. The contactor is used to provide the main source of power to the pump motor, while the starter is used to control the speed of the motor. The contactor, pump motor starter and overload relay all contain contactors, contact points and switches.

The overload protection on the EHU2-12 is designed to shut down the system in the event of an overload. If the contactors become overloaded, both circuits will shut down. The overload relay also works as a safety device, providing an additional layer of protection. In the event of an overload, the overload relay will open the circuit before the contactors and the motor starter, preventing further damage.

In addition, the EHU2-12 also comes with a current transformer to monitor the current for the motor and pump. This current transformer allows the accessory to detect any abnormalities in the current and can also be used to monitor temperature changes, allowing the system to operate in energy-saving mode when not in use.

Conclusion

EHU2-12 is an accessory designed for pumps and motors primarily used in industrial applications. Its two circuits are used to control the speed of the motor and pump while also providing overload protection and other features. Its current transformer also provides an additional layer of safety by monitoring the current and temperature of the system. Thanks to the EHU2-12, industrial businesses can ensure their pump motors run safely and efficiently.
