INNOVATIVE DESIGN & PROTOTYPE TESTING are key components of
BRYANT’S success in “IMPROVING POWER BY DESIGN.” But it
doesn’t stop there. Total commitment to component testing, reliability
testing, environmental testing, destruction and life testing, plus testing
to applicable CSA, NEMA, EGSA, and other standards, allows you to
choose CARRIER with the confidence that these systems will provide
superior performance.

MOTOR STARTING ABILITY
SOLID-STATE, FREQUENCY COMPENSATED VOLTAGE REGULATION.
This state-of-the-art power maximizing regulation system is standard on
all Bryant models. It provides optimized FAST RESPONSE to changing
load conditions and MAXIMUM MOTOR STARTING CAPABILITY by
electronically torque-matching the surge loads to the engine.
SINGLE SOURCE SERVICE RESPONSE from Bryant’s dealer network
provides parts and service know-how for the entire unit, from the engine
to the smallest electronic component. You are never on your own when
you own a BRYANT SYSTEM.
BRYANT TRANSFER SWITCHES. Long life and reliability are
synonymous with BRYANT SYSTEMS. One reason for this
confidence is that the BRYANT product line includes its own transfer
systems and controls for total system compatibility.

GENERATOR FEATURES
Four pole, revolving field generator, directly connected to the engine shaft
through a heavy-duty, flexible disc for permanent alignment.
Generator meets temperature rise standards for class “F” insulation as
defined by NEMA MG1-22.4 and NEMA MG 1-1.65.
Stator windings are “trickle” varnished and rotor windings are “roll-dipped”
for complete impregnation.
Unit tested for motor starting ability by measuring instantaneous voltage
dip with an oscillograph.
All models utilize an advanced wire harness design for reliable interconnection
within the circuitry.
Magnetic circuit, including amortisseur windings, tooth and skewed stator
design, provides a minimal level of waveform distortion and an electromagnetic
interference level which meets accepted requirements for standard AM radio,
TV, and marine radio telephone applications.
Voltage waveform deviation, total harmonic content of the AC waveform,
and balanced T.I.F. (Telephone Influence Factor) have been evaluated to
acceptable standards in accordance with NEMA MG1-22.
Alternator is of drip-proof guarded construction.
Fully life-tested protective systems, including “field circuit and thermal
overload protection” and standard main line circuit breakers capable of
handling full output capacity.
System torsional acceptability confirmed during prototype testing.
