The 777 AccuPower is a fully-programmable, 3-phase motor and pump protection relay. It allows for entry of motor hp rating, full-load amperes, efficiency, and power factors, and will then accurately calculate motor output power. The 777 AccuPower relay is most useful with mag-drive pumps or process applications where the process power is desired over the utility power. Voltage, current, and power measurements can be displayed as well as fault information and setpoints. The built-in display simplifies troubleshooting and allows the user to easily and precisely configure setpoints.
The 777 AccuPower can be used with the optional COM 4-20 output communication module to give an analog signal proportional to output shaft power. Other optional accessories include the RS485MS-2W comms module; the RM1000 remote monitor; and the RM2000 remote monitor. See the accessories products for complete information.
Features & Benefits:
- Built-in display: Visual indication for programming, viewing real-time voltage or current, and last fault code
- Motor output power measurement: Allows use of process power over utility power
- Network communications capability: Limited Modbus capabilities using RS485MS-2W communications module
- 3 programmable restart delay timers: Allows separate restart delay time for rapid cycle protection, motor cool down, and dry-well recovery
- Remote display compatibility: Increases safety through remote display of real-time data and fault history. Aids with arc-flash safety regulations
