Specications
The Model 201A
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. The Model 201A includes
advanced single LED diagnostics, where five
different light patterns distinguish between faults
and normal conditions.
This unique microcontroller-based voltage and
phase-sensing device 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.
For more information see:
See Appendix A, page 68, Figure 8 for dimensional
drawing.
See Appendix B, pages 73 & 74, Figures 12 & 13 for
typical wiring diagrams.
