Optional Accessory Engine coolant and oil heater, Alternator space heater, Cooling for heat exchanger, Control system with RS232/485 communication interface, Battery charger by main supply, Fuel-water separator, Daily fuel tank, ATS & paralleling system, Soundproof Canopy and Moving Trailer. ATS SYSTEM For emergency power usage in building, Auto transfer switch (ATS) is essential. ATS can automatic transfer load from Mains power supplying to Emergency power. In normal, when the Main power supplying failure or voltage drop below 80% of normal voltage, ATS will auto start Emergency generator set after a preset time of 0-10 sec (adjustable according to the users). Once generator reach at rated speed, the ATS will transfer the load to emergency generator sets automatically
