3309P-1-204 - Brand New BOURNS Trimmer Potentiometers
-
Description
The 3309P-1-204 is a trimmer potentiometer belonging to the product category of trimmer potentiometers, which are electronic components used for adjusting and calibrating resistive values in circuits. This specific model is designed as an Adaptive Alternator Voltage Regulator, aimed at regulating the output voltage in diode-rectified alternator charging systems common to automotive applications. One of its key features is the provision of either an analog or digital fixed frequency duty cycle (ON/OFF ratio) control of an alternator’s field current. It also boasts four Load Response Control (LRC) rates selectable by connecting pins 7 and 8 to ground, which facilitate controlling the alternator field current under prevailing engine conditions to eliminate engine speed hunting and vibrations caused by abrupt torque loading of the engine owing to sudden electrical loads being applied to the system at low engine RPM. Additional features include stable output voltage with minimal variation over engine speeds and field current levels, externally controlled MOSFET and field flyback diode recovery characteristics for minimum RFI (Radio-Frequency Interference), and trimmable devices available at 14.6 V and 14.8 V (typical) Vset.
