Multiquip MQ Power 36 kW 45 kVA WhisperWatt Mobile Diesel Generator with TRLR45 Trailer (DCA45SSIU4F)
The Multiquip DCA45SSIU4F 45 kVA WhisperWatt Mobile Diesel Generator Package delivers versatile three-phase and single-phase prime electrical power engineered for commercial construction jobsites, municipal utility bypass operations, disaster relief stations, and outdoor event staging. Driven by an EPA Tier 4 Final turbocharged 65.7 BHP Isuzu 4LE2X liquid-cooled diesel engine, this mobile system provides a 36 kW continuous prime output (40 kW maximum standby rating) while restricting operational noise down to an ultra-quiet 66 dB(A) at 23 feet.
Equipped with an open-delta alternator winding design for high inductive motor-starting capacity, an electronic isochronous governor maintaining 60 Hz line frequency within ±0.25%, and an internal 79.2-gallon fuel reservoir with environmental containment, this generator supports up to 49 hours of continuous run time at half load. Factory mounted directly to the Multiquip TRLR45 heavy-duty tandem-axle highway trailer (7,000 lbs GVWR), this turnkey package delivers immediate jobsite mobility, versatile multi-voltage selection, and continuous power generation under tough contractor duty cycles.
Recommended Jobsite Applications
- Commercial Building & Infrastructure Projects: Running high-amperage jobsite sub-panels, structural welders, concrete saws, multi-operator tool stations, and temporary field offices.
- Municipal Bypass & Utility Dewatering: Delivering uninterrupted 3-phase 240V or 480V power to municipal trash pumps, submersible dewatering units, and sewer bypass equipment.
- Emergency Facility Standby: Providing automated emergency power to lift stations, telecommunication towers, and municipal maintenance yards via automatic transfer switch (ATS) integration.
- Entertainment & Urban Sound-Sensitive Venues: Supplying clean, frequency-stabilized power for large concert lighting rigs, film trailers, and urban street work requiring strict 66 dB(A) sound containment.
Key Performance & Functional Features
- Tier 4 Final Isuzu 4LE2X Engine: 2.2L 4-cylinder turbocharged, charge-air cooled diesel provides efficient fuel burn and simple maintenance without requiring complex DPF regeneration cycles.
- Complete TRLR45 Highway Trailer Package: DOT-compliant tandem-axle trailer rated at 7,000 lbs GVWR featuring dual 3,500 lb axles, surge hydraulic brakes, heavy-duty suspension, and multi-hitch coupler capability.
- WhisperWatt Sound-Attenuated Enclosure: Heavy-gauge, powder-coated steel housing lined with dense acoustic sound-dampening insulation keeps sound output to 66 dB(A) at 23 feet under full prime continuous load.

💡 PHASE BALANCING & VOLTAGE SELECTION TIP: When operating in three-phase 120/208V or 277/480V modes while simultaneously powering 120V auxiliary site tools, distribute single-phase branch circuits evenly across Phase A, Phase B, and Phase C lugs. Keeping current draw balanced within 10% across all three legs prevents line voltage unbalance, optimizes generator fuel efficiency, and ensures clean voltage regulation for sensitive diagnostic gear.
