Car Power Inverter Selection Knowledge:
1: Car Power Inverter Instructions:

The vehicle-mounted power inverter is a DC-DC converter, which is widely used in remote and data communication, computers, office automation equipment, industrial instrumentation, and military applications.In the fields of aerospace and other areas, it involves all industries and sectors of the national economy.
Based on the size of the rated power, DC/DC converters can be divided into three categories: 1.6W～250W, 250W～750W, and 750W～1KW. Since the 1990s, DC/DC converters have entered the 21st century.The growth rate in the low power range has significantly increased, with the highest growth rate occurring in 6W～250W DC/DC converters, which are widely used in DC measurement and testing equipment, and computing.The system displays, computers, and military communication systems. Due to the high-speed development of microprocessors, the trend of DC/DC converters moving from low power to medium power is inevitable. Therefore, 250W～The growth rate of the 750W DC/DC converter is also relatively fast, mainly due to its application in service-oriented medical and laboratory equipment, industrial control equipment, remote communication equipment, multi-channel communication, and transmission equipment.Delivering equipment, DC/DC converters have a broad application prospect in the fields of remote and digital communication.

The vehicle-mounted power converter is applied to large trucks and buses, converting the direct current (DC) 24V to direct current (DC) 12V to power car electronics such as car audio systems, subwoofers, navigation devices, and driving recorders.
The product is developed using advanced PWM chip technology, and the power conversion operates in the ultra-audio range. It significantly reduces the size and weight of the entire machine, while ensuring that the circuit operates without noise.Status. This product is designed with multiple protection circuits, including 1. Short-circuit protection, 2. Overload protection, 3. Direct-connect protection, and 4. Power-off memory. It can effectively protect electrical appliances and automotive circuits during use. When the output is connected to the vehicle, it will automatically detect the vehicle's battery voltage and current, and then start the charging process.When the output current exceeds the rated output, it can quickly cut off the output circuit to effectively protect the safety of the electrical equipment.

Part Two: Installation and Usage Method:
1. Place the voltage reducer in a ventilated and dry environment and make appropriate fixations.
2. Connect the 24V input terminal to the power supply connector. Connect the red wire to the positive pole, the yellow wire to the car key switch wire (ignition switch wire), and the black wire to the negative pole.
3. Connect the 12V output to a 12V electrical device. Connect the red wire to the positive pole. Connect the yellow wire to the ACC (REM) wire of the device. Connect the black wire to the negative pole.
The long-term working current of electrical appliances should be less than the rated current of the transformer. After wiring, please ensure good insulation to prevent short circuit phenomena.
4. Turn on the vehicle's power supply to power the converter, and the converter's indicator light will turn on.
5. Turn on the power switch of the appliance to make it work normally.

 Three: Product Use Precautions:
1. Please do not use for a long time beyond the rated current, to avoid causing a fault.
2. Please do not use this product for a long time when the car engine is turned off, or the car may have trouble starting due to the low battery voltage.
3. Please strictly follow the safety precautions when using this product.
4. Do not use this product in high-temperature, humid, or dusty environments.
5. Please do not disassemble or modify this product.
