Most regulators offered today
in automotive and aircraft fields
are the "switching" variety. That
is, alternator field voltage is
controlled by succession of pulses;
field excitation is turned completely
on and off several hundred times
per second. Switching regulators
have performed well in aircraft
for many years past but LORAN
systems and composite airplanes
mandate critical reconsideration
of potential radio noise sources.
Linear regulators generate no
audio or radio noise. The B &
C Model LR-3 functions as a linear
regulator. Further, the LR-3 contains
solid-state over voltage protection
and low-voltage warning light.
To acquire capabilities equal
to the LR-3 one may have to purchase,
install and wire three separate
devices.
The LR-3 is the only regulator
offered to general aviation which
automatically adjusts bus voltage
by sensing battery temperature.
This combination of features in
a single product makes the B &
C LR-3 a lightweight, space-saving
and cost-effective alternative
for an aircraft electrical system.
Compatible with most alternators
used in contemporary aircraft
systems. 14 or 28 Volt Regulators
output is overload and short circuit
protected.

The LS-1 Alternator Control has
the same features as the LR-3
- however, it has been specially
designed to turn a 14 Volt Alternator
into a 28 Volt Alternator. B &
C Specialty Products, Inc. is
proud to have been selected as
supplier for the historic VOYAGER
flight. Two specially modified
alternators and two LR-2 voltage
regulators were used successfully
during the VOYAGER flight around
the world.
