MultiQuip DCA20SPXU4F Mobile Generator Overview
The MultiQuip DCA20SPXU4F is a trailer-mounted single-phase diesel generator rated at 20 kW prime and 22 kW standby, with 120/240V output. It is powered by a Tier 4 Final Isuzu 4L32T diesel engine rated at 40.2 BHP at 1,800 RPM. It is positioned for contractors, emergency response teams and remote site managers who need compact, quiet power on job sites, at events and in remote operations.
The generator uses a brushless design with an automatic voltage regulator, and a mechanical governor controls engine speed. A sound-attenuated, weatherproof steel housing keeps noise to 65 dB(A) at 23 feet. A remote auto start/stop system and an easy-access analog control panel with an ammeter, frequency meter and AC circuit breaker keep operation simple.
A 41.7-gallon fuel tank supplies the engine, and the integrated trailer includes pintle and ball coupler options. The trailer has a GVWR of 3,500 lb, and the specification table below lists the electrical, trailer and weight data in full.
Voltage regulation is listed at plus or minus 0.5 percent from no load to full load, and frequency regulation at plus or minus 3 to 5 percent in steady state. The generator end is a revolving-field, drip-proof, single-bearing design with brushless excitation. Dry operating weight is 1,797 lb, and the trailer measures 105.79 x 56.18 x 20.85 inches.
