• Fuel tank capacity: 470 L
• Control panel: TELYS standard, APM802 optional
• Version: Enclosed (Fully Weather Proof Silent Enclosure)
• EPA Compliant: Non-EPA Export Only

Ratings follow ISO 8528-1 and are stated at 25°C air inlet temperature and 100 kPa barometric pressure. Multiple voltage configurations are available, from 200/115 V through 415/240 V.

Volvo Engine Performance and Fuel Efficiency

At the core of this generator set is the Volvo TAD1344GE, a 12.78 liter engine with air to air charge cooling. Its electronic governor holds frequency regulation to within +/- 0.5%, which protects sensitive loads from fluctuation.

• Fuel consumption at 100% load: 83.10 L/h
• Fuel consumption at 75% load: 63.30 L/h
• Fuel consumption at 50% load: 42.80 L/h
• Maximum standby power at rated RPM: 399 kW
• Oil capacity: 36 L

These figures give operators a clear basis for planning run time and refueling intervals. The radiator and mechanical fan are designed for a wiring temperature of up to 48/50°C, and the unit is delivered with oil and coolant rated to -30°C.

V440C2 IV - SDMO - KOHLER | 352 kW 440 kVA Alternator Characteristics

The AT01741T alternator is a single bearing, direct coupled design with no collar or brush, which reduces wear parts and routine maintenance. AVR regulation keeps voltage steady as loads change.

• Insulation class: H
• Efficiency at 100% load: 93.10%
• Total harmonic distortion: under 1.5% at no load, under 2% on load
• Protection rating: IP 23
• Unbalanced load acceptance ratio: 70%
• Motor starting capacity: 729 kVA

Low harmonic distortion makes this unit a sound match for electronics, drives, and other equipment that needs clean power. A 500 ms recovery time after a 20% transient voltage dip helps the set respond quickly when large loads come online.

Control Panel Options for Simple Operation

The standard TELYS control unit combines a large display screen, buttons, and a scroll wheel for easy menu navigation. It gives operators the information they need at a glance, without specialized training.

• Electrical measurements: voltmeter, frequency meter, ammeter
• Engine parameters: hours counter, oil pressure, coolant temperature, fuel level, engine speed, battery voltage
• Alarms and faults: oil pressure, coolant temperature, failure to start, overspeed, emergency stop
• Communication: remote control and operation software, USB and PC connections

For multi-set installations, the optional APM802 system adds a full touch screen interface designed for power plant management. Its customization function complies with IEC 61131-3, and it suits hospitals, data centers, and industrial sites.

V440C2 IV - SDMO - KOHLER | 352 kW 440 kVA Dimensions and Enclosure Options

This generator set is offered as a compact open unit or with a sound attenuated enclosure, so it can be matched to the installation site. Each version is built on a mechanically welded chassis with antivibration suspension.

• Compact version: 3160 x 1340 x 1805 mm, 3110 kg dry weight
• M228 enclosure: 4475 x 1410 x 2430 mm, 4080 kg dry weight
• M228 DW containment: 4527 x 1410 x 2700 mm, 4740 kg dry weight, 1368 L tank
• Enclosed sound level: as low as 68 dB(A) at 7 meters

The M228 DW version nearly triples fuel capacity for extended run time between fills. Standard equipment also includes a main line circuit breaker, a 24 V charge alternator and starter, and a starting battery with charger.
