Main features of power module1060v wide input voltage, suitable for most power supplies on the market as input source.The output is constant voltage and current, and the voltage and current are continuously adjustable. Suitable for most uses electrical equipment.High output power, good ventilation and natural heat dissipation can reach 280W/12A (Note that there are output power and output current limits).The module adopts a step rectification scheme with high efficiency and an output voltage of more than 10V.As high as 92%96% or more,There is a constant current indicator when charging the battery. The charging status is clear at a glance.The input has a 15A fuse. Reverse input polarity will not damage the power supply (it will Burned fuse, need to replace the fuse)Module parametersModule name: 400w stepdown constant voltage and constant currentModule nature: nonisolated stepdown moduleInput voltage: 10.560VOutput voltage range: 045V (must meet voltage reduction conditions, IN input multiplied by 0.8)Minimum output voltage: 0V (+1V)Maximum output voltage: approximately input x 0.8 (for example, 40V, 40V x 0.8=32V Highest)The appearance and color of different batches of products may be different, which will not affect the use.color: blueMaterial: PCBPackage Contents:1 x ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
