Features:This is a 200W DC to DC step-up power supply module for electric equipment, digital products, laptop, etc.Input and output are designed with screw terminals for convenient wire connection and disconnection.Highefficiency, the maximum conversion efficiency can be 97.6% and efficiencyis related to input/output voltage and current.Designed with a big heat sinks that would ensure a better heat dissipation.Aluminum outer case will protect step-up module and also good for heat dissipation.Specifications:Input Voltage: DC6V to 35VOutput Voltage: DC6V to 55V (out voltage must be higher than or equal to input voltage)Max. Input Current: 10A (lower for long time working)Max.Output Current: 7A (lower for long time working)Max. Output Power: 200W (input voltage >30V)Max. Conversion Efficiency: 97.6% (32V convert to 45V, 3A. Efficiency is related to input/output voltage and current)Size: 70 x 39 x 32mm / 2.75 x 1.53 x 1.26"Package Includes:1 x ModuleNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering..
