 More
than a voltage regulator, LR3C is an alternator control system.
This combination of features is normally
available only as separately purchased and installed items. Originally
designed for the Voyager, around-the-world aircraft, the LR3C represents
the best that technology can offer in a single, cost effective package.
Virtually all regulators offered in automotive and
aircraft markets are the "switching" variety. They control an alternator
with short pulses of full battery voltage. These pulses occur several
hundred times per second. The rapid switching action does generate some
electrical noise. Output from an LR3C is a smoothly adjusted voltage generating
no noise whatsoever. A switching regulator may perform well in your airplane,
especially if the ship is all metal and does not carry LORAN. However,
no alternator system should be operated without true over-voltage protection.
In addition, a means for timely notification of alternator failure is
recommended. The LR3C provides all these features in a proven product
with minimal installation and wiring requirements. The LR3Cs track record
began with a 216-hour flight around the world. The record goes on to list
hundreds of units in service, thousands of flight hours and over 6 years
of production. The LR3C is all solid-state and compatible with 14 or 28-volt,
aircraft or automotive alternators. Will not work if alternator has a
built-in regulator.
Supplied with low-voltage warning lamp assembly and
complete installation instructions. Specify 14 or 28-volt. Alternators
with built-in voltage regulators must be modified before installation
with the LR3C.
The optional LR3C temperature sensor adjusts bus voltage
by sensing battery temp. This feature is especially useful in areas of
extreme climate temperature changes. |
