Input voltage range: wide voltage input: 17V-65V Output current: maximum 10A; output power 120W. Our voltage buck converter adopts synchronous rectification technology to further improve the conversion efficiency and good stability. The power conversion efficiency can reach 95%; ripple wave: 50Mv; start-up delay time: less than equal 2S. Better safety, equipped with smart chip of voltage regulator, providing over-current, overload, low load, overvoltage, undervoltage, overheating and short circuit intelligent protection. High quality, easy to use, buck converter is made of aluminum shell, epoxy resin potting, waterproof, dustproof, moisture-proof, shockproof and better heat dissipation, more durable. We combine the battery adapter and voltage converter with 2 heat-resistant wires. It is more convenient to use. Just install the battery to the battery adapter and connect the voltage converter to the device. (Note: Batteries are not included) This power inverter has a wide range of uses and is very suitable for upgrading motors, riding toys, golf carts, trucks, speakers, monitoring equipment, power tools, LED light strips, work lights or robot DIY, etc. The styles and colors of accessories may vary from batch to batch, but it does not affect the use.
