R85049/84-20Z02 Application Field and Working Principle

R85049/84-20Z02 is a solid-state contactor for high voltage and current control. It is commonly used in industrial automation control systems, power distribution systems, and high voltage motor drives. This contactor is designed to provide reliable and safe switching in electrically noisy environments.

Principle of Operation

R85049/84-20Z02 contactors use a PTC thermistor (positive temperature coefficient) to switch the high voltage and current. A PTC thermistor is a temperature-sensitive device with a positive temperature coefficient. This means that when the temperature of the contactor increases at a given temperature the resistance of the thermistor will also increase, thus increasing the current flowing through the contactor. When the temperature of the contactor reaches a certain point, the resistance of the PTC thermistor will exceed the current flowing through the contactor, thus breaking the current and disconnecting the high voltage and current. When the temperature is reduce below the given point, the current will start flowing through the contactor again and the high voltage and current will be connected.

Applications of R85049/84-20Z02 Contactors

R85049/84-20Z02 contactors are extensively used for controlling high voltage and current in industrial automation systems, power distribution systems, and high voltage motor drives. They can be used in a wide range of applications including switching lights, motors, pumps, and other electrical devices.These contactors are also widely used in robotics, such as in industrial robots for industrial or manufacturing purposes. They are also used in power supplies, as well as for controlling motors and transformers.

Advantages of R85049/84-20Z02 Contactors

R85049/84-20Z02 contactors provide several advantages over traditional mechanical contactors. They are much more reliable and efficient than traditional contactors as they are not affected by normal wear and tear. As the contactor does not have any moving parts, it is much safer than traditional contactors.Additionally, the contactor is easy to install, as it requires only two wires for connection. The contactor also provides a much longer life and is capable of handling large currents and voltages.

Conclusion

The R85049/84-20Z02 solid-state contactor is a high voltage and current control device that is used extensively in industrial automation and power distribution systems. It uses a PTC thermistor to switch the high voltage and current, thus providing reliable and safe switching, and a long life with no mechanical wear or tear. These contactors are also easy to install, and provide several advantages over traditional contactors.
