S4EB-3V

S4EB-3V application field and working principle

The S4EB-3V is a compact and solid power relay that works based on electrically controlled mechanical switching. It is specifically designed to be used as a undervoltage/ overvoltage protective relay. This relay has two output contacts and one feedback contact.

Application field

This powerful relay is mainly used in industrial, aerospace industry, instrumentation, and automation/ control systems. It can be used for many purposes, such as for controlling electric circuits, motors, pumps, switches and more. This relay can also be used in machines, so that if the voltage drop below or rises above a certain range, the machine can be switched off automatically. In addition, it can be used in battery- powered systems, to provide a backup power supply to the system when the battery runs out of charge.

Working Principle

The S4EB-3V is made up of two separate contacts, one contact is for undervoltage protection and the other is for overvoltage protection. Voltage is applied to both contacts and the contacts are opened or closed whenever the input voltage is higher or lower than the required set values. The feedback contact is connected in series with the output contact and, depending on the type of relay, it can provide an adjustable current. This current can be adjusted to match the required set values of the system.

Features and Benefits

• The S4EB-3V is a reliable and durable power relay that offers long-term operational efficiency.
• It offers excellent electrical insulation for undervoltage protection and overvoltage protection.
• Its contacts are durable and highly resistant to wear and tear.
• It is cost-effective and easy to install and configure.
• The feedback contact provides adjustable current to match the required set values.

Conclusion

The S4EB-3V is a powerful and reliable power relay that is widely used in industries, aerospace industry, instrumentation, and automation/ control systems. It provides excellent electrical insulation for undervoltage and overvoltage protection. Its durable contacts are highly resistant to wear and tear. Furthermore, it is cost-effective and can be installed and set up easily. It also offers adjustable feedback contact that can match the system’s set values.
