AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...
The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a phase loss, phase reversal, phase unbalance, undervoltage or overvoltage condition ...
*2. Phase-sequence: The state in which phase sequence of three-phase power line is not positive. For example, a motor rotates backward when the phase sequence is reversed. *3: Voltage asymmetry: The ...
