Power Supply (car) converter purchase knowledge:
1: Power Supply (car) converter description:

Power Supply (car) converter is a DC-DC converter. (DC/DC) converter is widely used in remote and data communication, computers, office automation equipment, industrial instruments, military aerospace and other fields involve all walks of life in the national economy.
According to the rated power, DC/DC converter can be divided into 1. 6W ~ 250W,250w ~ 750W, 750W ~ 1KW,3 categories. In the 1990 s, DC/DC converter the growth rate in the low power range is greatly increased, among which 6w ~ 250WDC/DC converter has the highest growth rate, because they are widely used in DC measurement and test equipment, calculation computer display system, computer and military communication system. Due to the high speed of microprocessor, the development of DC/DC converter from low power to medium power is an inevitable trend, so 250w ~ the growth rate of 750W DC/DC converter is also fast, which is mainly used for service medical and experimental equipment, industrial control equipment, remote communication equipment, multi-channel communication and development. Transmission equipment and DC/DC converter have broad application prospects in the field of remote and digital communication.

Power Supply (car) converter is applied to large trucks and passenger cars, which converts 24V DC into 12V DC, and supplies power to vehicle electrical appliances such as car audio, subwoofer, navigator, driving recorder, etc.
The product is developed by using advanced PWM chip technology. The power conversion works in the ultra-audio range. While greatly reducing the volume and weight of the whole machine, the circuit works without noise. Status. This product is designed with multiple protection circuits, 1. Short circuit protection 2. Overload protection 3. Straight-through protection 4. Power-off memory. In use, it can effectively protect electrical appliances and automobile circuits, when the input when the output current exceeds the rated output, the output circuit can be cut off quickly to effectively protect the safety of electrical equipment.

2. Installation and usage:
1. Place the pressure reducer in a ventilated and dry environment and fix it properly.
2. Connect the 24V input terminal with the power supply connector,. Red spread is connected to the positive pole, the yellow wire is connected to the car key switching line (ignition switching line), and the black wire is connected to the negative pole.
3. Connect 12V output with 12V electrical appliances. Red spread connect to the positive pole. The yellow wire is connected to ACC(REM) wire of the electrical appliance. The black wire is connected to the negative pole.
* The long-term work current of electrical appliances should be less than pressure reducer of the rated current. Please do insulation after wiring to prevent short circuit.
4. Turn on the power supply of the car to supply power to pressure reducer, and the indicator light of pressure reducer is on.
5. Turn on the power switch of the electrical appliance to work normally.

 3. Precautions for product use:
1. Please do not use the rated current for a long time to avoid failure.
2. Please do not use this product for a long time when the car engine is off, so as not to make it inconvenient to start the car because the battery voltage is too low.
3. Please strictly observe the precautions of electrical appliances and use this product.
4. Do not use this product in high temperature, humidity and dusty places.
5. Please do not decompose or transform this product.
