4. ການຕິດຕັ້ງແລະການຕິດຕັ້ງ

This inverter unit is designed for integration into custom circuits or existing appliances. Follow these steps for basic setup:

1. ກະກຽມແຫຼ່ງພະລັງງານ: Ensure you have a stable 12V DC power source (e.g., a car battery, 12V power adapter). The input voltage range is 8V to 12V DC.
2. ກໍານົດການເຊື່ອມຕໍ່: Refer to Figure 3.4 for the input and output terminals. The 12V DC input has clearly marked positive (+) and negative (-) terminals. The 220V AC output is labeled as A + B port.
3. Connect DC Input: Carefully solder or connect your 12V DC power source to the designated input terminals, observing correct polarity. Connect the positive lead of your DC source to the '+' terminal and the negative lead to the '-' terminal.
4. Connect AC Output: Connect your 220V AC load (e.g., energy-saving lamp, router) to the A and B output ports. Ensure all connections are secure and insulated to prevent short circuits.
5. ການຕິດຕັ້ງ: Secure the circuit board in a stable, well-ventilated enclosure to protect it from physical damage and ensure proper heat dissipation.

Note: This unit is a bare circuit board. Proper enclosure and insulation are required for safe operation.

5. ຄໍາແນະນໍາການດໍາເນີນງານ

Once the unit is correctly installed and connected, follow these steps for operation:

1. ຢືນຢັນການເຊື່ອມຕໍ່: Double-check all DC input and AC output connections to ensure they are secure and correctly polarized.
2. Apply DC Power: Turn on your 12V DC power source. The inverter unit will begin converting the DC power to AC.
3. Connect AC Device: Plug your 220V AC device (up to 40W) into the output of your circuit.
4. ການຕິດຕາມປະສິດທິພາບ: Observe the connected device to ensure it is functioning correctly. If any issues arise, immediately disconnect the power source and troubleshoot.
5. ກຳລັງຕັດການເຊື່ອມຕໍ່: To turn off the system, first disconnect the AC load, then turn off the 12V DC power source.

Important: Do not exceed the 40W output capacity. Exceeding this limit can cause damage to the inverter and connected devices.
