Easy to use; LED indicates the current measurement of the input or output voltage; The voltmeter can be turned off by another button; Adopts 12A high quality inductor input current can be reached at 7A similar products on the market are used in ordinary 5A inductor; Special precision voltmeter can also be manually calibrated. Performance parameters 1.Input voltage range: 3~35V DC(Note: the input voltage is less than 4V voltmeter failure) 2.Input current: 7A 3.Output voltage range: 3.5-35VDC(please to ensure that output voltage above on input voltage) 4.Output current: 6A (max) 5.Output power: 75W (when the input and output voltages greater than 16V up to 100W) 6.Conversion efficiency: 96% (max) 7.Voltmeter range: 4 to 40V error +/-0.1V 8.Short circuit protection: Yes (limit current 14A); (Note: connected to high-power load just switched on the impact of current very general meeting current limiting self-locking protection it is recommended to be switched on firstly and then access the load). 9.Input reverse polarity protection: None (if required high current diode in series with the input)
