ONITOR
Operation of the Switchback 6600CE power supply on only two phases
causes the output to approximate a 100-120 Hz rounded edge square
wave. The optional phase monitor will shut off the Switchback
6600CE if one or more input phase falls below 180 VAC. The phase
monitor board has a normally closed 0.5 amp 250 VAC dry contact
available on the output signal connector for external use. When the
voltage on the low phase increases to over 180 VAC the phase monitor
will automatically restart the power supply.
Note: Since phase alignment is not important to the Switchback 6600
CE Power Supply, the phase monitor does not check phase alignment.
This feature may be purchased with the standard Switchback 6600 CE
or in conjunction with the Governor Board.

This feature adds a ground fault interrupt circuit that shuts off the
power supply in the event of a ground fault. Power to the supply must
be cycled to restart after a ground fault.
The ground fault interrupt circuit trips at 30mA AC.
The GFCI option also adds an additional over voltage shutdown circuit
should the output voltage of the Switchback 6600 CE exceed 250 VDC.
This feature may be purchased with the standard Switchback 6600 CE
or in conjunction with the Governor Board, and/or Phase Monitor.
