14IVR-21

14 IVR-11, 14 IVR-12, 14IVR-21, 14IVR-22 MONOCHIP CAR ALTERNATOR REGULATOR Description Alternator regulator 14IVR-XX, made under the integrated technology is essentially a monochip voltage regulator for the car alternators with the rectifier nodes on the Zener diodes. The single chip combines the control functions and the powerful output cascade with IField=5 A to control the generator excitation circuit. The alternator regulator 14 IVR-XX does not require application of other external components, which considerably reduces the system cost as a whole and enhances its reliability.
