777-AccuPower
The Model 777-AccuPower
is a fully-programmable 3-phase motor and pump
protection relay. It allows motor hp rating, full
load amps, efficiency and power factor to be
entered and will accurately calculate motor output
power. This 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 SymCom’s
4-20mA output module to give an analog signal
proportional to output shaft power.
For more information see:
See Appendix A, page 66, Figure 1 for dimensional
drawing.
See Appendix B, page 71, Figures 1 & 2 for typical
wiring diagrams.
