DescriptionModel Number : LTC1871Compale Brand/Model : NoneBrand Name : SZEKSOrigin : Mainland Chinais_customized : NOModel Number : DC-DC 100WType : Voltage RegulatorCondition : NewCompale : PlayStation MoveDC DC-DC 3~35V to 3.5~35V LTC1871 Booster step up Step-up module Converter Regulated Power Supply+VoltMeterDescriptionQuality new with high qualityColor: as picture showSize:67.5mmx41.5mmx14mm/2.66"x1.63"x0.55"(inch) (approx).Performance parameters:1.Input Voltage:3-35V DC (Note: When input voltage is less than 4V, onboard voltmeter will not work).2.Input Current:9A (max).3.Output Voltage:3.5-35V DC (this board is boosting board, output voltage>=Input voltage).4.Output Current:6A (max).5.Output Power: 65W (when the input and output voltage greater than 20V up to 100W).6.Conversion Efficiency: 96% (the highest).7.Output Ripple:40mV(TYP).8.Onboard Voltmeter Range:4-40V .9.Error:+/-0.1V.The module has high power output and efficiency (up to 96%). The output can be up to 65W (and can further reach 100W when enhance heat-transfer).Onboard we have a voltmeter to show clearly the input / output voltage (we can select to show input/output voltage by pressing on the button onboard). When the "IN" LED lights on, the voltmeter displays input voltage; When the "OUT" LED lights on, the voltmeter displays output voltage. We can also turn off the voltmeter LED by removing the jumper cap at "P3 (please refer to below image)".We can easily adjust voltage by the potentiometer onboard and the voltmeter onboard. We won't even need a multi-meter when adjusting. Very convenient Note 1: No reverse connection protection, please pay attention to see the positive and negative input terminal.Note 2:The power module useage requires basic electronic circuit, improper use can damageIN+: Input PositiveIN-: Input NegativeOUT+: Output PositiveOUT-: Output NegativeThis product adopts boost IC American imported and high power MOS tube, output large power, high efficiency (96%), wide working voltage, the output power reaches 65W, when the input and output voltage is above 20V, it can be achieved when the 100W output power.Package Included1 Pcs LTC1871 Booster Step Up Step-up Module
