Aideepen Step Up Converter, 1800W 40A DC-DC Boost Converter, adjustable constant voltage and constant current 14-85V to 14-120V

["Output power: 1800W; Input voltage range: 14-85V; Output voltage range: 14~120V; Input current: Max 40A; Output current: 1.5~20A(±0.5A). (Upgrade information can be found on the description page.)","Equipped with input reverse protection and undervoltage protection to ensure safe and worry-free use, can be used for car battery reinforcement, battery charging, etc. Equipped with a spare fuse that can be replaced and maintained by the user.","Optimize the circuit design and increase the fast shutdown of the MOS tube to ensure more stable output voltage. Suitable for high-power LED, motor, digital products, solar panel voltage regulator, etc.","When the load is light, the fan does not rotate. When the load temperature reaches about 40 degrees, the fan rotates automatically. This effectively reduces noise and extends the lifespan.","Try not to use the highest or lowest input and output voltage. It is strictly forbidden to change the output current by short-circuiting. Charging super capacitors is strictly prohibited. (If you have any questions, please contact us)","The insulating plate of the main power tube is made of high-quality aluminum oxide, with thermal conductivity 10 times higher than that of a regular insulating pad. Oversized silicon-iron-aluminum magnetic ring with four 1.2 pure copper enameled wires, low heat generation and high efficiency.","User manual: Please enter all characters in brackets (http://8.217.75.21/Aideepen/DE-B0DTKC1QMV.pdf)"]
