Altitude: <1000M
Relative Humidity: <90%
Technical Parameters: 
Signal Voltage (AC):
Terminal V0-V220 Input 180-250VAC: 50/60Hz
Terminal V0-V380 Input 370-450VAC, 50/60Hz
Output (DC): Maximum continuous 6A, 90VDC (220VAC input)
Maximum Output Current (DC): up to 12A, 10 seconds
Excitation Winding Resistance: Minimum 8Ω
Voltage Input (AC): 180~250VAC, 45-60 Hz.
Voltage Adjustment Range: 180-250 Vac: 370-480Vac
Pressure Regulation Accuracy: <±0.5% (when engine variation is less than 4%)
Voltage Drift: <0.05%/°C
Response Time: <1 cycle
Built Voltage: AVR input voltage is greater than 8Vac, 35Hz
Parallel CT: rated current ratio 1 common current transformer

Wiring:
1. V0-V220, V0-V380 voltage measurement input.
2. E+, E-excitation output.
3. X1-X2 power input terminal, this power supply can be PMG, full harmonic, auxiliary winding, line power supply, etc.
4. S1-S2 current compensation input, using current transformer secondary side current is 1A.
5. VR1-VR2 remote voltage regulation, connected to 1KΩ/1W adjustable resistor. First adjust the adjustable resistor to about the midpoint and connect it to VR1 and VR2. Then adjust the AVR voltage to adjust the potentiometer to the voltage to be adjusted. The adjustable resistor can adjust the output voltage by ±20V.
6. A1-A2 accepts an external DC voltage source to control the generator output voltage, and is connected to a voltage source of ±1V. With TRIN potentiometer, the adjustment range is -20--+20V

Adjustment Settings:
1. OTLT: generator output voltage adjustment, CW adjustment of output voltage drop, CCW rise
2. STAB: The generator voltage stability is adjusted, and the stability is strengthened, and CCW is weakened.
3. UFRO: low frequency protection setting, CW frequency decreases, CCW frequency increases
4. DIP: V/Hz reduction ratio adjustment during low frequency protection, CW decrease, CCW increase.
5. DROOP: Current compensation component adjustment, CW reduction, CCW increase.
6. TRIM: Analog voltage input component adjustment, CW reduction, CCW increase. This potentiometer is on the front left corner of the AVR.
