## Description

Product Others Parameter:Static operating current: 10mA (12V liters 20V, the higher the output voltage is too static current will increase)Output voltage: 10-60V continuously adjustable (the default output of 19V shipments, for other voltage, please note to the treasurer.)Output current: 12A MAX more than 7A Please strengthen the heat (with the input and output differential pressure, the greater the difference in output current smaller)Constant current range: 0.2-12AOutput power: = input voltage *10A, such as: enter 12V*5A=60W, enter 24V*5A=120W, type 36V*5A=180W, type 48V*5A=240W,Operating temperature: -40 ~ +85 degrees (ambient temperature is too high, please strengthen the heat)Operating frequency: 150KHzConversion efficiency: up to 96%Over-current protection: (input more than 15A, automatically reduce the output voltage, a certain range of error.)Input reverse polarity protection: None (if more reverse current is needed, please input the diode in series)Installation: 4 2.5mm screw holesWiring: Wiring outputApplications:1, DIY a regulated power supply, input 12V can, the output can be 12-50V adjustable.2, For your electronic equipment, power supply, you can set the output voltage with your system voltage.3, As a car power supply for your laptop, PDA or a variety of digital products.4, DIY a high-power notebook mobile power: with large-capacity 12V lithium battery pack,so that your books where you can light to where.5, The solar panel regulator.6,To the battery, rechargeable lithium batteries.7,Drive high-power LED lights.Package Included:1 x 400W constant voltage boost moduleTips:Please do not short-circuit the way to adjust the current, boost the circuit structure of the module can not be short-circuit way.
