5) LED light module 1pcs
II. Boards SPECs
Since the AC board is the biggest and the one which determines the finished machine's performance, we show its complete parameters here for your reference. If you really are interested in our products, please contact us directly for the parameters of the other boards.
1. Technical Performance
This product is a control board for the unidirectional inverter series, designed for lithium iron phosphate battery input and AC 220VAC output. It is used to power devices that require AC power from batteries or DC voltage. The product includes various protection functions such as input over/under-voltage, output overload, output overcurrent, over-temperature, short circuit, etc.
2. DC Input Parameters
Rated Voltage: 19.2VDC Voltage Range: 17.5VDC~21.9VDC
3. Environmental Parameters
Operating Temperature: -10°C~50°C
Operating Humidity: 20%~90%
4. AC Output Parameters
Rated Voltage: 220VAC sine wave
Rated Power: 600W
5. Protection Performance
A. Input Overvoltage Protection
If DC input voltage is detected above 22.2V for 100ms, the inverter activates overvoltage protection.
B. Input Undervoltage Protection
If DC input voltage is detected below 17.5V for 100ms, the inverter activates undervoltage protection.
C. Input Overcurrent Protection
For the 600W inverter, if DC input current exceeds 39A, the inverter activates overcurrent protection (non-recoverable).
D. Output Overload Protection
If the output power exceeds 600W, the inverter limits power output based on the load. When the actual load surpasses the inverter's output capacity, the output is shut off.
E. Output Overcurrent Protection
For the 600W inverter, if output current exceeds 10A, the inverter activates overcurrent protection (non-recoverable).
F. Overtemperature Protection
If the heatsink temperature exceeds 100 degrees Celsius, the inverter activates overtemperature protection, which is not recoverable.
6. LED Indicators
Both front and rear control stages have LED indicators for fault display. When a fault occurs, the LEDs will blink to indicate the type of fault as follows:
A. Front Stage Fault Indications:
1) Overpower Fault: Fast blink 1 time
2) Overcurrent Fault: Fast blink 2 times
3) DC Board Communication Fault: Fast blink 3 times
4) Overvoltage Fault: Fast blink 4 times
5) Overtemperature Fault: Fast blink 5 times
6) Front and Rear Stage Communication Fault: Fast blink 6 times
7) Fan Abnormality: Slow blink 1 time
8) Undervoltage Abnormality: Slow blink 2 times
9) Temperature Sensor Abnormality: Slow blink 3 times
10) Heatsink High Temperature Abnormality: Slow blink 4 times
B. Rear Stage Fault Indications:
1) Overcurrent Fault: Fast blink 1 time
2) Short Circuit Fault: Fast blink 2 times
3) Overload Fault: Fast blink 3 times
4) Overtemperature Fault: Fast blink 4 times
5) Overvoltage Fault: Fast blink 5 times
6) Undervoltage Fault: Fast blink 6 times
7) Temperature Sensor Abnormality: Slow blink 3 times
8) Heatsink High Temperature Abnormality: Slow blink 4 times
7. Communication
The AC mainboard and DC mainboard use a 485 isolated communication interface.
8. Interfaces
600W Inverter Interfaces:
BAT+ 2. BAT- 3. AC220V 4. Front Stage Temperature Sensor 5. Fan
Power Control 7. 485 Communication 8. Rear Stage Temperature Sensor 9. Spare
9. Dimensions
600W PCBA: 200 x 120mm
10. Notes
1) The inverter control interface includes power control and 485 communication control.
2) Standard battery configuration includes 6 series lithium iron phosphate batteries; other battery types require custom PCBA.
III. All the boards are developed and built in house.
IV. We accept sample order of below 10 sets for the function and reliability tests.
Warmly welcome your enquiries!
