B&C AVC1 Quick Start Manual

The AVC1 is an external voltage regulator/rec fier
designed for use with single-phase permanent-magnet
alternators up to 20A in size. Over-voltage protec on,
Charging System-fault and Low-voltage warning
output, and field-adjustable charging voltage are
integrated into the AVC1 control package.
Terminals 1 & 2 - AC Input
Terminals 3 & 4 - DC Output (+)
Case - Ground VOLT ADJ - Voltage Regula on Adjustment
CONFIG - LV Warning Configura on
♦
For Duca retrofit, AVC1 may be installed with no
wiring changes. Otherwise, refer to Diagrams 1 & 2
(reverse) for suggested wiring configura ons.
♦
Disconnect ship's ba ery, Nega ve (-) post first.
♦
Mount the AVC1 & filter capacitor (if used) on the
firewall or selected loca on, terminal strip DOWN.
♦
Wire the AC input. Connect Terminals 1 & 2 to the
two AC leads from the alternator/dynamo, using
the supplied wire terminals and heatshrink, if
needed. Note: there is no polarity in these wires.
♦
Wire the DC power (+) output. Connect Terminals
3 & 4 to the posi ve (+) post on the filter capacitor
(if used) and the aircra bus at the output current
limiter(s) or panel circuit breaker.

The AVC1 provides warning output for Charging-
System Fault (CSF) and Low-Voltage (LV) condi ons.
LV warning is user-selected to trigger at one of three
voltage thresholds. It may be disabled, also, if desired.
LV warning-select DIP switches
LV warning op ons may be selected by
posi oning two small
DIP switches behind
the machine screw
cap labeled "CONFIG"
on the side of the
AVC1 enclosure. The
factory preset is 12.7v.
♦
Wire the Warning Output. Connect Terminal 5 to
appropriate EFIS input or the panel indicator light.
♦
Wire the Control Circuit. Connect Terminal 6 to the
ba ery/alternator master switch.
♦
Wire the Ground circuit. Using 12AWG M22759/16
wire, connect one of the two moun ng flanges on
the AVC1 to the aircra firewall Ground, Grounding
block, or ba ery Nega ve (-) post.
♦
Connect ship's ba ery, Posi ve (+) post first.
♦
Test the installa on. Perform a normal engine start.
Charging should be indicated at 13.8v to 14.4v. LV
indica on may occur ini ally, but should cease as
bus voltage rises above the selected warning
threshold.
