Converter DC-DC step down XL4015E1 0-5A 0,8-30V Converter XL4015E1 - 0-5A - 0,8-30V Module with impulse converter step-down. Input voltage range: from 5 do 32V, maximum current capacity 5A. The popular XL4015 converter lowers the input voltage do of a given output voltage, and limits the output current using multi-turn potentiometers in an easy way. ( potentiometers have a wide scale approx. 50 revolutions ) Twisted ARK2 terminals at the output and input allow simple and secure attachment of wires. This converter has the function of charging lithium batteries: Li-Ion, Li-Pol. It is necessary to set the output drink according to the charged packages, and the optimal charging current of the battery. After these treatments, you can connect the do converter. Two status LEDs inform about the charging process: the LED from the inside lights up when the battery is charged (significant current consumption), and the LED from the outside lights up when the battery is charged (minimum current consumption). Technical data: Input voltage: from 5 V do 32 V Output voltage adjustable from 0,8 V do 30 V. Maximum continuous output current: 5 A (when walking) Driver: XL4015E1 Efficiency: less than 90 % (depending on power consumption) Switching frequency: 180 KHz - 48KHz Four mounting holes (solder pads) with a diameter of 2 mm Dimensions: 51 x 26 x 12 mm Masa : 19 g Connection Method: The module has 4 screw connectors. IN Input drink - positive pole. IN- Input drink - negative pole (masa). OUT Output drink - positive pole. OUT- Output drink - negative pole (masa).
