ゃōゃThe soft film light box loses power when connected to the inverter
Do you want to ask why the soft film light box loses power when connected to the inverter? The reasons why the soft film light box loses power when connected to the inverter are insufficient output power of the inverter, inverter failure, and cable connection problems. Soft film light boxes are usually powered by DC power, and an inverter is a device that converts DC power into AC power. The reasons for power outage when the soft film light box is connected to the inverter are as follows:
1. Insufficient output power of the inverter: The output power of the inverter must meet the power demand of the soft film light box. If the power of the inverter Insufficient, unable to provide sufficient power supply to the soft film light box, resulting in power outage.
2. Inverter fault: The inverter may have faults, such as internal circuit short circuit, overload and other problems. These faults will cause the inverter to fail to work properly, causing the soft film light box to lose power.
3. Cable connection problems: The cable connection between the soft-film light box and the inverter may have problems such as poor contact, looseness or short circuit. These problems will cause poor current transmission and lead to power outages.

To change the 12v light box advertising power supply to 14 volts, you need to change the 431 voltage dividing sampling circuit. To convert 12V to 14V, an inverter is used to boost the voltage. After the inverter and boost, it must be rectified and filtered before the battery can be charged. DC power using a transformer is ineffective. The inverter converts DC power (battery, storage battery) into AC power (220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit.
