Power Supply
It is designed to organize round-the-clock power supply of devices powered by 24 V DC, including telemechanics, relay protection and automation equipment. The module provides uninterrupted automatic switching of the power supply of the consumers connected to its output from the main supply input to the backup input and vice versa in case of loss or impermissible deviation of the voltage parameters.
