Specications
The Model 102A
is a 3-phase, auto-ranging, dual-range voltage
monitor that protects 190-480VAC, 50*/60Hz
motors regardless of size. The product provides
a user selectable nominal voltage setpoint and the
voltage monitor automatically selects between the
200V and 400V range.
A unique microcontroller-based voltage and
phase-sensing circuit constantly monitors the
3-phase voltages to detect harmful power line
conditions. When a harmful condition is detected,
the MotorSaver’s output relay is deactivated after
a specified trip delay. The output relay reactivates
after power line conditions return to acceptable
levels. The Model 102A includes advanced single
LED diagnostics. Five different light patterns
distinguish between faults and normal conditions.
For more information see:
See Appendix A, page 68, Figure 7 for dimensional
drawing.
See Appendix B, page 73, Figures 10 & 11 for typical
wiring diagrams.
