DCA-400SSK — GENERAL INFORMATION

Engine

The DCA-400SSKis powered by a 4 cycle, water cooled, turbocharged KOMATSU Model SA6D140E-2 diesel engine. This engine is designed to meet every performance requirement for the generator. Reference Table 1, page 16 for engine specifications.

Electronic Governor System

The electronic governor system replaces the standard mechanical governor system. The frequency regulation improves from ±3.0% regulation with the mechanical governor to ±0.25% regulation with the electronic governor system.

JacketWater Heater (OPTIONAL)

The jacket water heater is a 1500-watt heater designed to keep the coolant warm in the engine block for fast starts and load acceptance. The heater is thermostatically controlled and once an acceptable engine temperature is achieved it will cycle on and off, operating only about 1/3 of the time, which makes it more efficient than the direct block type heater. It is designed to keep the engine coolant between 100 and 120 degrees Fahrenheit.

Under normal conditions, 20 to 15 minutes is required to raise the engine temperature of a cold engine to 100 degrees Fahrenheit.

Battery Charger

The battery charger will operate in a ‘BOOST’ mode until the battery’s current acceptance falls to 70% of the charger’s rating. The charger will then go into a ‘FLOAT’ mode, where it discharges a lower voltage until an AC failure, or the battery is discharged.
