Doosan Engine Performance

The Doosan P126TI is an 11.05 liter engine with a 123 x 155 mm bore and stroke and a 17:1 compression ratio. It delivers a maximum standby power of 272 kW at rated speed. An electronic governor holds frequency regulation to +/- 0.5%.

• Fuel consumption at 75% load: 43.60 L/h
• Fuel consumption at 50% load: 30 L/h
• Oil capacity: 25 L
• Radiator and engine coolant capacity: 50.50 L
• Exhaust gas temperature: 560°C

Air to air charge cooling and a mechanical fan radiator support operation in ambient temperatures up to 48/50°C. The unit is delivered with oil and coolant rated to -30°C. A 24 V charge alternator, starter, and starting battery with electrolyte are also included.

D300 II - SDMO - KOHLER | 240 kW 300 kVA Alternator and Voltage Options

The AT01800T alternator is a single bearing, direct coupled design with no collars or brushes. It carries Class H insulation and IP 23 protection. AVR regulation is standard, and efficiency reaches 93% at full load.

• 415/240 V: 417 standby amps
• 380/220 V: 456 standby amps
• 220 TRI: 787 standby amps
• 200/115 V: 866 standby amps
• 240 TRI: 722 standby amps

Total harmonic distortion stays below 2.5% both at no load and on load. The alternator accepts a 100% unbalanced load ratio and offers 538 kVA of motor starting capability. This makes it suitable for sites with mixed or inductive loads.

Control Panel Choices

The standard APM303 panel operates in manual or automatic mode and has an LCD screen. It measures voltages, currents, power, power factor, and energy. It also displays fuel level, oil pressure, and coolant temperature.

• Modbus RTU communication on RS485
• Safety monitoring for overspeed, oil pressure, and coolant temperature
• Minimum and maximum voltage and frequency protection
• Stack of 12 stored events
• 2 configurable reports

The optional TELYS panel adds a large display, scroll wheel navigation, and USB and PC connections. For power plant applications, the optional APM802 provides a full touch screen interface. Its customisation function complies with IEC 61131-3.
