Brush Excitation with AVR: Ensures ±2% voltage regulation under load
Self-Regulated: Consistent voltage output for sensitive equipment
IP23 Protection: Suitable for ventilated environments
Coupling Options: IM B34, IM B35, SAE – compatible with standard generator frames
Applications
Mobile and standby generator sets
Power supply for voltage-sensitive tools and electronics
Construction, industrial, and commercial equipment
Rural electrification and backup systems
OEM integration where AVR regulation is required
