Series: 777-KW/HP-P2

The 777-KW/HP-P2 is a 3-phase current and voltage monitor that provides unsurpassed protection by combining overload, voltage, phase loss and reversal, voltage and current unbalance, power monitoring*, and underload trip based on power into one efficient unit. The underpower trip feature is desirable anytime the current vs. load characteristic is non-linear or has little change. In general terms, smaller motors and slow-speed motors have little change in current over the normal load range. Larger motors that are running light loads will also show small current changes over the operating load range. The low and high power protection feature increases reliability for non-linear motors where the load characteristic has little change.

For standalone applications, these units incorporate a 3-digit LED display that is used for programming, providing real-time operational information, and displaying diagnostic codes to aid in troubleshooting a fault condition. These units also feature a communications network port that can be used with communication modules, listed in the 777 accessories section, to form a Modbus, DeviceNet**, Profibus, or Ethernet network. Up to 99 units can be remotely monitored and controlled from a PC, PLC, or SCADA system, and data logging through a PC with the optional Solutions software.

*Low current trip and high power trip are network programmable only. **DeviceNet is a trademark of its respective owner.
