Multiquip MQ Power 20 kW 25 kVA Super-Silent Mobile Diesel Generator (DCA25SSIU4F)
The Multiquip MQ Power WhisperWatt DCA25SSIU4F 20 kW (25 kVA) Diesel Generator delivers switchable three-phase and single-phase electrical output engineered for commercial jobsite distribution, utility repair fleets, sound-sensitive live productions, and automatic emergency standby backup. Driven by an EPA Tier 4 Final turbocharged 40.2 BHP Isuzu 4LE2T liquid-cooled diesel engine, this versatile power station delivers a 20 kW continuous prime rating (22 kW maximum standby output) while maintaining an acoustic sound level of just 65 dB(A) at 23 feet.
Equipped with an open-delta alternator winding for enhanced motor-starting capacity, an electronic governor maintaining 60 Hz line frequency within ±0.25%, and an internal 41.7-gallon fuel tank with 124% fluid containment, the DCA25SSIU4F operates for up to 44 hours at half load without ground-spill risk. Outfitted with a complete analog gauge cluster and 2-wire auto-start remote terminals, this compact unit delivers reliable power across demanding field environments.
Recommended Jobsite Applications
- Commercial Building & Infrastructure Projects: Supplying clean 208V/240V three-phase and 120V single-phase power for site trailers, masonry saws, and multi-bank cordless tool charging stations.
- Utility Bypass & Municipal Pumping: Running continuous 3-phase 240V or 480V electric submersible dewatering pumps and municipal bypass setups.
- Sound-Sensitive & Urban Operations: Powering film trailers, broadcast trucks, and municipal night street repairs requiring strict 65 dB(A) noise limits.
- Facility Emergency Standby: Providing automated emergency power to clinics, commercial refrigeration units, and telecommunications nodes via transfer switch integration.
Key Performance & Operational Features
- Tier 4 Final Isuzu 4LE2T Diesel Engine: 2.2L 4-cylinder turbocharged engine uses a DOC aftertreatment system that requires no DEF, simplifying field fuel logistics and servicing.
- Multi-Voltage Distribution Selector: Lockable selector switch enables rapid reconfiguration across 3-phase 208V, 220V, 240V, 416V, 440V, and 480V, as well as single-phase 120V and 240V lines.
- WhisperWatt Sound-Attenuated Enclosure: Heavy-gauge, powder-coated steel housing lined with sound-dampening acoustic insulation keeps operating noise to 65 dB(A) at 23 feet under full prime continuous load.
- Patented Open-Delta Alternator Winding: Delivers superior motor starting capacity, allowing the alternator to start heavy electric motors and inductive loads without excessive voltage drop.
- Long-Range 41.7-Gallon Fuel Cell: Internal fuel tank provides extended runtimes of up to 44.3 hours at 50% load and 25.7 hours at 100% full continuous prime load.
- 124% Environmental Fluid Containment: Integrated double-wall chassis basin captures fuel, engine oil, and radiator coolant to safeguard against jobsite ground spills.
- Analog Control Console & Auto-Start: Shock-mounted dashboard includes an AC ammeter, frequency meter, running hour meter, and two-wire remote auto start/stop terminal block.

💡 MOTOR STARTING & LOAD MANAGEMENT TIP: The DCA25SSIU4F features an open-delta alternator winding that provides high motor-starting kVA. When sizing branch circuits for inductive motor loads (such as 3-phase submersible pumps), utilize the 240V or 480V three-phase settings to minimize line amperage drops and maintain full 60 Hz frequency stability during high-demand motor starts.
