Features: 1.Every product has a unique Manufacturing Part Number label on the inner package that proves it has been qualified,which include Part Number,Model Number and inspection date information;2.If you have any questions about the item,please provide us the Manufacturing Part Number for checking,your profits will be guaranteed.3.Output voltage: 1-35V continuously adjustable The input voltage of the step-down power supply should always be greater than the output voltage and at least 1V voltage difference, input power = output power + loss (energy conservation principle).4.Output current: 15A (MAX) The marked current within 10A for a long time is the maximum current under specific conditions (measured 12 drops 5V) The actual output current is not fixed, it is related to the input and output voltage difference, temperature and other conditions.5.Output power: good ventilation, natural heat dissipation power: 100W for a long time, and the maximum heat dissipation can reach 200W. If you work for a long time, please pay attention to the temperature rise and do a good job of heat dissipation.6.Uses: suitable for college students, engineers, technicians, factory DIY, electronic enthusiasts and other personnel.Specifications:Appearance: with shellRectification mode: synchronous rectificationType: Non-isolated Buck ModuleInput voltage: 8-55V (limit 60V, please leave a margin)Operating temperature: -10-85 DegreeWorking frequency: 180KHzConversion efficiency: up to 94% (efficiency is related to input, output voltage difference, output current)Material: MetalColor: SilverBrand name: BQLZRSize: 70x40x30mm/2.76inchx1.57inchx1.18inch (LxWxH)Weight: 160gPackage include:2 x Buck Converter DC8-55V to 1-35V 15A
