What is Siemens 7UG0818-1CA20 Line Monitoring Relay?
The 7UG0818-1CA20 is a relay from Siemens, providing line monitoring dedicated for industrial and commercial purposes. This relay automatically monitors the power supply continuously to safeguard the electrical systems from voltage asymmetries, phase sequence errors, and phase failures. Therefore, it keeps all motors and sensitive equipment running within conditions of safe voltage from expensive downtimes and damage.
Main Features
Voltage Monitoring- Works with the under-voltage and over-voltage conditions thereby truly ensuring the stability of the system.
Phase Monitoring- The phase checks for any errors in phase sequence, thus saving motors from destruction.
Customized Adjustable Settings- These are very much application specific.
LED Indicators- once a test is conducted, it will show the output clearly for the troubleshooting.
Compact Design- The area where the device is to be installed can then easily fit into a very small control panel holding design.
Wide Voltage Range- The application extension is possible significantly by allowing multi-voltage suitability.
