About the product

Precautions for Use:
1. Installation Precautions:
All installation, connection, and inspection tasks must be performed by qualified professionals with relevant expertise. Install the voltage regulator in a moisture-proof area within the generator and ensure it is placed in a location not easily accessible to unauthorized personnel. Under normal operating conditions, the surface temperature of the regulator may exceed 60°C. Do not touch the heat sink during operation; a warning label has been affixed to indicate this precaution.

2. Adjustment Procedures:
a. Low-frequency Adjustment (U/F):
For 50Hz operation, insert the jumper between terminals C and 50 (factory setting). For 60Hz operation, insert the jumper between terminals C and 60. The U/F potentiometer sets the frequency threshold for low-frequency protection. Follow these steps for adjustment: Start the engine and establish the voltage. Adjust the engine speed to the desired low-frequency value. Slowly adjust the U/F knob until the red indicator light on the AVR illuminates (factory settings: 47Hz at 50Hz, 57Hz at 60Hz).
(Note: When the red LED indicator lights up, it signifies insufficient frequency. In this condition, the output voltage will decrease due to the activation of the low-frequency protection circuit, preventing excessive excitation current from damaging the field stator coil).

b. Voltage Adjustment (VOLT):
Adjust the "voltage potentiometer" to the rated value (turn clockwise to increase). For external voltage adjustment, connect VR, 1K or 1/2K between terminals "1" and "2". If no external VR is connected, short-circuit terminals "1" and "2".

c. Stability Adjustment (VOAB):
Adjusting the "stability adjustment" potentiometer can stabilize the generator's output voltage. However, excessive adjustment may cause increased instantaneous voltage variation under heavy load. It is recommended to run the generator set without load and verify that the speed is correct before adjusting the "stability adjustment" potentiometer. Turn the potentiometer fully clockwise, then slowly rotate it counterclockwise until the generator voltage begins to fluctuate. The correct setting is slightly clockwise from this point.
