200W 7A 6-35V To 6-55V High Power Step Up Boost Converter Charger Module With Aluminum Case 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. High efficiency, the maximum conversion efficiency can be 97.6% and efficiency is 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 35V Output 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 Module Note: 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.
