Electronic Kit DC-DC Converter High Efficiency 95% 5A 75W Power use LM2596 ICProduct DescriptionProduction ConditionBrand NewProduction NameDC-DC power supplyModel NumberDC-DC 5A 75WShippingFree USA,Other Country: USD4 Specification: Tips: If customer cannot adjust the output voltage, it shows equal to the input voltage. When you encounter this problem, first rotates counterclockwise of potentiometer 10 laps or more, then you can use the module properly regulate the voltage. Because of the factory default setting.This module is different from the market LM2596, XL4005 buck module, they use the chip design power, respectively 15W, 50W, this buck module - Upgrade the chip in the input and output voltage range, output power, efficiency should be better than similar products, the power can be 75W, a very high price.Module Highlights:● 5A power high-efficiency step-down low ripple!● with power indicator light!● Onboard voltage meter, voltage meter can self-calibration, there will be no problem of inaccurate voltmeter! !● with heat sink!● Get pillars! ! !Module performance and features:● with power indicator light● voltmeter with voltage meter display and self-calibration. It uses a more advanced microprocessor voltage, voltage meter error of ± 0.05V, range 0 ~ 40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is 4.5V or more)● measure the touch of a button to switch the input or output voltage, and has a light show which is being measured voltages, and save the settings, even if the power is turned on again.● voltmeter can be turned off when not needed, touch the left button can be easily achieved.● with a terminal block, no iron can also be easy to use, and retention wire connection points.● Input voltage 4.0 ~ 38V. (Input voltage must be higher than the output voltage 1.5v above)● adjustable output voltage range of 1.25V ~ 36V continuously adjustable. (1.5V input voltage must be higher than the output voltage)● output current up to 5A, recommended in 4.5A.● output power up to 75W.● high conversion efficiency, up to 96% (efficiency of input and output voltage, current, pressure related)● Load Regulation S (I) ≤0.8%, voltage regulation S (u) ≤0.8%● overheating protection and short circuit protection● Size 66 * 39 * 18mm● Weight 28gOnboard voltage meter self-calibration method:1. On-board voltage table shows the output voltage, long press on the right button for two seconds after the release, and the output voltage voltmeter indicator "OUT" synchronous flashing, this time into the output voltage adjustment mode; Similarly, the voltmeter shows when the input voltage, long press on the right button for two seconds after the release, voltmeter and input voltage LEDs "IN" synchronous flashing, this time into the input voltage adjustment mode;2. Touch the button on the right side, the voltage increases a unit, touch the button on the left side, a voltage reduction unit; since the voltage value of a unit is less than 0.1V, so you need to press 1-5 times in a row to see the voltmeter change the 0.1V, specifically continuous button several times depending on the voltage value currently displayed, the current display higher the voltage, the fewer the number of press;3. voltage adjustment is completed, press the right side button for two seconds after the release, this time to exit voltage calibration mode, all parameters set to automatically power-down save.NOTE: You only need to adjust the way this one can obtain accurate calibration voltage value across the entire voltage range, this function is more accurate to meet your requirements and design, ease of use.Package Include:1unit x power supplyPackage and Shipping InformationPacking: bubble wrap + cartonSize: Weight: Est. 300gShipping: Item will be shipped within 2 working days after full payment is received.
