BRUSHLESS ALTERNATORS

CEN C715 and C716 Alternators

Description and Operation

The

C715C715

C715 alternator (14 V, 360 A) and

C716C716

C716 alterna-

tor (14 V, 400 A) are internally rectified. All windings

and current-transmitting components are non-

moving, so there are no brushes or slip rings to wear

out. This unit is externally energized through either

an ignition switch or an energize switch (commonly

an oil pressure switch), which activates regulator.

Field coil is then energized. Regulator maintains

alternator output voltage at regulated setting as

vehicle electrical loads are switched on and off.

Alternator output current is self-limiting and will not

exceed rated capacity of alternator.

A2-128 regulator used with all units has R terminal

for optional AC voltage tap. A 15.5 V regulator set-

point is available for battery isolator applications.

Electromagnetic interference (EMI) is suppressed with

internal filters to acceptable levels defined by the

Society of Automotive Engineers (SAE) specification

J1113/41. A2-128 regulator will not reduce EMI from

sources such as antennas, poor cable routing prac-

tice, or other electronic devices that cause EMI. If EMI

continues, consult an electromagnetic compliance

(EMC) specialist to determine EMI source.
