Introduction of the most complete automobile generator regulator in history

What are the definitions of conventional terminals for automotive generator regulator, what are the characteristics of P / D regulator, PCM regulator and Lin regulator, what are the basic characteristics / functions of the regulator, and what are the differences between single function regulator and multi-function regulator.

1. Conventional terminal definition of automotive generator regulator:

B +: output terminal of generator

F: Connect the excitation coil.

E: Ground.

P: Detect the state of generator phase signal.

S: Connected to the positive pole of the battery to detect the battery voltage

C: Used to reduce the output of the generator and reduce the engine load.

50: Battery indicator,.

Ig: ignition switch connected to car

Fr or DFM: computer controller connected to the vehicle

R: Provide excitation current when the generator starts

W: Connecting the computer controller

2. P / d end regulator

P: Connect the vehicle ECU and feed back the working state of the regulator.

D: Connect the vehicle ECU. Drive the regulator to work.

Stator: detect the state of generator phase signal

3. PCM regulator

RC: receives PWM signal from ECU and drives regulator.

Li: connect the ECU of the car. Feed back the working state of the regulator and adjust the PWM input.

4. Lin regulator

Lin or C: upgraded version of PCM regulator. The PCM control is changed into programmable load response control feature and two-way communication interface

5. Basic characteristics of the regulator:

Speed characteristics

Voltage regulation

temperature coefficient

Load characteristics

Power module voltage drop

Load rejection withstand voltage

Leakage current

Speed of pressure building

6. Function of regulator

Self excitation function

Load delay response

Soft start

Low voltage warning

Over voltage warning

Short circuit protection function.

7. What are the differences between single function regulator and multi-function regulator

Single function regulator refers to only the basic function of regulator, voltage regulation function

Multi function regulator refers to one or more functions such as short circuit protection and soft start besides the basic characteristics of the regulator
