General Features
At the heart of the QSV45KS-EU generator lies the powerful Kubota V3800DI-T-BG engine, paired with the reliable LSA42.3M7 alternator from Leroy Somer. The advanced Microprocessor control module PLC-920 orchestrates smooth engine operations while efficiently indicating any faults. Features include a 63A SCHNEIDER main circuit breaker, mechanical governor for precise speed control, self-excited SHUNT excitation system for consistent voltage delivery, and A.V.R model R220 for accurate voltage regulation. Key and emergency stop switches, along with an ATS receptacle, enhance operational safety and flexibility. A 12V/60AH sealed maintenance-free battery is complemented by a lockable battery isolator switch. The generator is housed in a robust powder-coated canopy, supported by a 45℃ radiator and a steel base frame with vibration isolators to minimize noise and vibrations. The dry-type air filter ensures the longevity of the generator.
