|Product name:||High efficiency foot power vehicle waterproof voltage converter 24V to 19V20A380WDC-DC step-down power supply, 24V to 19V DC power converter|
|Function brief introduction:||This product adopts synchronous rectifier design, imported components, TI (TI) core, fine tuning circuit can be unstable between 22V to 35V arbitrary voltage high efficiency to convert 19V DC output stable, with undervoltage, overvoltage, overcurrent, overtemperature and short-circuit automatic protection function, and can automatically recover the normal work to meet the work conditions;|
Imported high conductivity organic silicone grease and epoxy resin potting airtight multi ribbed aluminum shell by making it more heat, high radiating performance, seismic, waterproof, moisture resistant characteristics, protection level of IP68.
|Applicable scope:||All need to 24V power supply voltage conversion to 19V, and to provide stable working voltage for 19V equipment occasions, expand the scope of application of 19V equipment.|
Such as solar power supply system, production line equipment, industrial control equipment, electric products, industrial control mainframe, notebook, industrial flat, Internet of things, vehicle networking equipment and so on.
|Input voltage:||24VDC (22~35V wide volt input)|
|Output voltage:||19V DC|
|Appearance color:||Silver gray precision die casting aluminum alloy shell|
|Product net weight:||0.55Kg/ station|
|Product features:||1, products listed for more than ten years, from the ocean to Gobi, from the high temperature cabin to the snow and ice, experienced a variety of environmental tests;|
2, imported components, TI core + fine tuning circuit, synchronous rectification design, conversion efficiency as high as 93%-96%, small heat;
3 、 undervoltage, overvoltage, overcurrent / overload, over temperature, output short circuit protection, stable and reliable product.
4, high thermal conductivity and high insulation silicone epoxy resin + airtight sealing, multi ribbed structure aluminum shell, ultra small size, waterproof and earthquake protection level of IP68;
|Common sense of power supply:||1. The output voltage of the power converter needs to be equal to the input voltage of the electric equipment or the input voltage range marked by the electrical equipment.|
2. The output current of the power converter is the maximum current that the converter can output, and the actual output current is decided by the electric equipment.
3, when purchasing power supply for the equipment, the peak power of the load equipment should be configured, rather than the common rated power.
4, different load types, the peak power and its rated power ratio is different. Such as motor, its starting peak current is generally 4-8 times the rated power, the minimum need to choose 2-3 times the rated power of the product.
5. The use of wires should meet the maximum current required to pass through the power converter. With 8-40V to 24V6A converter as an example, the maximum input current is calculated as: 24Vx6Ax1.17 (conversion overload protection point +7% 110% loss), 8V (minimum working voltage) =21.06A, should use 2.5mm2Copper cored wire
6, copper wire carrying capacity of wire safe carrying capacity is based on the allowed core temperature, cooling conditions and installation conditions to determine the. General copper wire safety 5~8A/mm2The safe carrying capacity of aluminum conductor, 3~5A/mm2
7, please accurately calculate the load power, in order to make the equipment to achieve the best use of the state, it is recommended not to exceed the power product marked power of 80% load, do not overload.
8, about vehicle voltage: at present, gasoline vehicles generally use 12V power, heavy diesel vehicles use 24V power.
9, because the battery discharge capacity is limited, in the opening of high-power load moment, the battery high current discharge will cause the battery output voltage greatly reduced
|Friendship tips:||1, please accurately calculate the load power, in order to make the equipment to achieve the best use of the state, it is recommended not to exceed the power product marked power of 80% load, do not overload. If you have any questions, please consult technical clothing.|
