The microcontrolled PLM Series of octal plug-in three-phase voltage monitors protects three-phase motors and other sensitive three-phase equipment from damaging or destructive voltage faults, the ...

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 need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

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 ...
