Features: Display part of the more advanced voltmeter microprocessor, boost part of original imported boost controller, by using the power MOSFET on resistance and eliminating the current detection resistance, maximizing efficiency, efficiency of up to 96.4%. Imported high-power low resistance MOS tube, large package, high current, high efficiency Schottky, ultra-wide thickened printed circuit board alignment, high-power high efficiency low temperature rise assurance. Ultra-wide voltage work, when the input and output voltage are above 20V can reach 128W output power. 100W High power and high efficiency, with power indicator Long life type switching power supply special high frequency high capacity low resistance (low-ESR) aluminum electrolytic capacitors, so that the output corrugation is lower. 12A Integrated inductor, so that the module input current in 7A (conservative parameters) can be long-term stable operation, greatly improving the performance of the module. Specifications: Input voltage: DC3-35V (Note: input voltage less than 4V, the on-board voltmeter fails) Input current: peak9A (recommended for use within 7A) Output voltage: DC3.5-35V (this board is booster board, the output voltage should be more than input voltage) Output current: Max6A (recommended for use within 5A) Output power: 75W(when the input and output voltage are greater than 16V can reach 100W) Conversion efficiency: Max96.7% On-board voltmeter range: 4-40V, error 0.1V Short circuit protections: Yes (limit current 14A). Warm tip: When accessing high-power load, due to the high-inrush current just after power on will limit the current self-locking protections, it is recommended to power on first, then access the load. Input reversal-protection: no (if-necessary, please series into the input high current diode) Note: Please allow 0-1cm error due to manual measurement. Please allow slight chromatic aberration due to different display resolutions. Package includes: 1x 100W Step-up Booster Module Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
