Features: 200W high-power boosting module, 6-35V boost 6-55V power module with aluminum shell, for electric equipment, digital products, laptops and more. High power boosting module, wide voltage input and output, convenient for DIY power supply. Up to 97.6% conversion efficiency, high output power (efficiency is related to input and output voltage and current). Output adjustable voltage, able to adjust to any voltage within the scope, meeting most of your voltage needs. The adjustable boost converter from DC6-35V to DC6-55V adopts aluminum shell design with good heat dissipation performances. The input and output designs have screw terminals for easy wiring and disconnection. Specifications: Material: Plastic+Metal Module size: approx. 70x39x32mm/2.76x1.54x1.26inch Input voltage: DC6-35V Output voltage: DC6-55V conversion efficiency 97.6% (measured when the input is 32V and the output is 45V/3A, the efficiency is related to the input voltage, output voltage, and current) Input: up to 200W (reaches largest power when input voltage is greater than 30V) Input current: up to 10A (please leave some margin for long time continuous operation) Output current: up to 7A (please leave a certain margin for long time continuous operation) Note: Attention: This board is a boost board, and the output voltage can only be greater than or equal to the input voltage! Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution. Package includes: 1Pc 200W Boost Module with Aluminum Shell
