5.3 Automatic Power Management (APM) Theory of Operation
Automatic Power Management (APM) Feature
When the IQC is connected to shore power and operating large AC loads it is possible that the
AC loads combined with battery charging requirements may exceed 30 amps. To prevent
nuisance tripping of the shore circuit breaker the Automatic Power Management circuit constantly
monitors the AC current entering input AC1. (Input AC1 is used to power the battery charger and
to power AC loads connected to the IQC output circuit when input AC2 is not used.) If the AC
input current exceeds 30 amps the APM circuit automatically reduces power to the battery
charger until either the AC1 input current is less than 30 amps or until the battery charger power
is zero. The APM circuit will override the Program Switch Bulk Charge Output Amps Setting and
proportionally reduce the battery charger output as necessary.
The optional APM Panel (Vanner part no. D07934) allows the operator to select the maximum AC
amps the battery charger may draw from shore power input AC1. The APM Panel allows the
Automatic Power Management Feature to be adjusted to match the size of the shore power
circuit breaker, 10 amps, 15 amps, 20 amps or 30 (default) amps. In motor home or similar
applications, where the shore power source varies from campground to campground, the APM
Panel is useful in preventing nuisance tripping of the circuit breaker at the shore power source.
This panel is usually installed near the shore power hookup.
Example 1: Input AC2 is not receiving power, the APM Panel switch is set at 15 amps and
the AC output load is drawing 10 amps. Under these conditions the APM will allow the battery
charger to draw up to 5 AC amps. If the AC output load is increased and exceeds the APM
setting then the battery charger will be reduced to zero AC amps.
Example 2:
Input AC2 is receiving power and the APM Panel switch is set at 15 amps. Under
these conditions the battery charger will be allowed to draw up to 15 AC amps regardless of AC
output load.
5.4 Automatic Throttle Control Terminal J31 Theory of Operation
Terminal J31 is provided on all model and is to be used on utility vehicles where the inverter
needs to operate continuous heavy AC loads and the vehicle is equipped with an Automatic
Throttle. Use J31 to turn ON the Auto Throttle to insure that the vehicle alternator is producing
maximum output whenever the inverter is powering a load.
J31 is controlled by the Load Demand circuit therefore Programming Switch 2 must be in the ON
position when Terminal J31 is used.
J31 is a 1/4" spade terminal located in the lower right midsection of the control circuit board. The
terminal is designed to provide ground control for a Bosch relay, Vanner part number 05235 or
equal. Install a 1 amp fuse in line near the inverter.
