    TECHNICAL SPECIFICATIONCHIDGE

    Generator
    400Hz 115/200 volts nominal, ±10% adjustable, 3 phase (0.8PF), 4 wire revolving field, brushless, self-cooling, permanently lubricated dual bearings, brushless rotating rectifier assembly, directly coupled to the engine. Engine and Generator vibration mounted. 

    Regulation
    1. Voltage regulation: ±1% over the full range of generator loading. 
    2. Voltage modulation: 0.5% at steady state. 
    3. Frequency regulation: ±2Hz Steady rate 

    Transients Recovery
    1. Frequency: To within ± 5Hz in<2 seconds 
    2. Voltage: to Within ± 1% in 100 milliseconds 

    Engine Specifications
    1. Cummins diesel engine or equivalent. 
    2. Air cleaner, full flow fuel and lube oil filters, 
    3. Muffler, heavy-duty radiator, blower type fan 
    4. And battery charge alternator. 

    Engine controls/instruments
    24 volt battery, ammeter, oil pressure gauge, running time meter, temperature gauge, fuel gauge, automatic shut down for low oil pressure and high coolant temperature. 

    Displays/Instrumentation
    1. Digital display: Factors including oil pressure, cooling temperature, fuel level and necessary factors are integrated in one LCD panel, which replaced traditional gauges. The operation is more convenient and easier than traditional type. All operation value is stored in the panel so that administrator can check it anytime. 
    2. Indicator lights for AC or DC output. 
    3. Switches for output operation and control power.
