Description
The Engga DX-5E (often identified by its model series GB-170) is an original-specification Automatic Voltage Regulator designed specifically for Engga brushless alternators. It plays a critical role in maintaining generator stability by regulating the excitation current based on the output voltage.
Known for its robust build and high reliability, the DX-5E is capable of operating in high-humidity and high-vibration environments. It features a simplified design for easy field replacement and is equipped with built-in protection circuitry to prevent damage to the generator’s exciter winding during over-load conditions.

Installation & Adjustments
- Voltage Adjustment: Use the “VOLT” potentiometer to set the rated output. Clockwise rotation increases the voltage.
- Stability Adjustment: The “STAB” trimmer adjusts the damping characteristic. If the voltage fluctuates at no load, turn it clockwise to increase stability.
- Under-Frequency (UFRO): Protects the exciter if engine speed drops. Default setting is usually 47Hz for 50Hz systems.
