• Compact version dimensions: 1405mm x 715mm x 1053mm, dry weight 387 kg, integral 50-liter fuel tank
• Soundproofed version (M126): 1750mm x 775mm x 1230mm, 530 kg, 71 dB(A) at 1m, 58 dB(A) at 7m, guaranteed sound power level 87 Lwa
• Standards: ISO 8528-1, Performance Class G1, delivered with oil and coolant rated to -30°C
• Version: Enclosed (Fully Weather Proof Silent Enclosure)
• EPA Compliant: Export Only

Available in both a compact open version and the quiet M126 soundproofed enclosure, the T12K is one of the most space-efficient and fuel-economical diesel generator sets in the SDMO Mitsubishi range, making it ideal for budget-conscious deployments where every liter of fuel and every square meter of floor space counts.

T12K Engine and Fuel Performance

The Mitsubishi S3L2-SD is a naturally aspirated, water-cooled 3-cylinder engine with a 22:1 compression ratio and a maximum standby output of 11.2 kW at rated RPM, running at the efficient 1500 RPM speed common to 50 Hz applications. 

Oil capacity is just 4.2 liters with an impressively low oil consumption rate of 0.018 L/hr at full load, and the combined radiator and engine coolant capacity of 4.2 liters keeps the thermal system simple and maintenance-friendly across extended run cycles.

T12K Alternator and Control Panel Options

The AT00350T brushless alternator delivers a continuous nominal rating of 11 kVA at 40°C and a standby rating of 12 kVA at 27°C, with 85.9% efficiency at full load and total harmonic distortion held below 2.6% at no load and 2.3% under load for clean power delivery to sensitive equipment. 

The standard APM303 controller handles both manual and automatic operation via an LCD display, monitoring phase-to-neutral and phase-to-phase voltages, active power, power factor, kWh energy metering, fuel level, oil pressure, and coolant temperature, with Modbus RTU communication on RS485 and a 12-event fault log for easy traceability. 

The optional TELYS controller adds a large scroll-wheel display, USB and PC connectivity, and a more comprehensive alarm management interface for operators who prefer a richer monitoring experience.

T12K Containment DW Enclosure Option

The optional M126 DW double-wall containment enclosure measures 1797mm x 775mm x 1391mm with an expanded integrated fuel tank capacity of 93 liters, nearly doubling runtime compared to the standard 50-liter open version. 

Acoustic performance is maintained at 71 dB(A) at 1 meter and 58 dB(A) at 7 meters with a guaranteed sound power level of 87 Lwa, making the soundproofed T12K well suited for noise-sensitive sites, indoor mechanical rooms, and installations requiring a fully self-contained, bunded fuel containment system in a single compact package.
