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 ...

To solve 3-phase voltage notching problems, use a 3% impedance reactor. When silicon-controlled rectifiers (SCRs) are used in electrical controls, we frequently experience line voltage distortion in ...
