[Module name]400W boost constant current module[Module properties]: non-isolated boost module (BOOST)[Input voltage]: DC8.5V-50V[Input current]: 1 (MAX) more than 8A, strengthen heat dissipation[Static working current]: 10mA (when 12V rises to 20V, the higher the output voltage, the higher the static current will increase)color: redMaterial: PCB, Metal[Output voltage]: 10-60V continuously adjustable (default output is 19V, if you need other voltages, explain to the shopkeeper.)12-80V fixed output (for bulk customers)[Output current]: If 12A MAX exceeds 7A, strengthen the heat dissipation (related to the input and output pressure difference, the larger the pressure difference, the smaller the output current)[Constant current range]: 0.2-12A[Output power]: = input voltage x 10A, such as: input 12V x =60W, input 24V x =120W,Input 36V x =180W, input 48V x =240W,[Working temperature]: -40~+85 degrees ( strengthen heat dissipation when the temperature is too high)[Working frequency]: 150KHz[Conversion efficiency]: 96% (efficiency is related to input, output voltage, current, and differential pressure)[Overcurrent Protection]: Yes (The input exceeds 1, the output voltage will be automatically reduced, and there is a certain range of error.)[Input reverse connection protection]: None, (If you need a higher reverse connection current, connect a diode in series with the input)[Wiring ]: Wiring output[module size]: length 67mm width 48mm height 28mmPackage Contents:3 x Step-up Boost ConverterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
