5.2 Automatic Power Transfer Switch Theory of Operation
The function of the Automatic Transfer Switch is to automatically accept AC input power from
shore or generator, and use this power to operate inverter loads and to provide power for battery
charging. Upon loss of AC input power, the transfer switch automatically switches the AC loads
back to inverter power. Transfer time is approximately 30 milliseconds (0.030 seconds). The
0.030 second transfer time allows all but the most sensitive loads to transfer from inverter power
to shore power and back to inverter power without interruption.
AC input voltage and frequency are monitored for proper tolerance at all times on AC1. When the
AC input is within tolerance for approximately 5 seconds, the power is passed through to AC3
output circuit and the IQC automatically switches from inverter mode to battery charger mode.
The IQC automatically switches back to inverter mode when input power is disconnected or when
input power is no longer within tolerance. See IQ Series Specifications page for AC input voltage
and frequency tolerances. The 5 second delay occurs only if the inverter is fully ON when input
