Sell Cre PCF *-Automatic-Lifter Regulator Module Stabilizer 7A / 80W Power Supply Module best price

Input voltage: DC 4.5ml x 30V do not reverse or reverse, otherwise damage Output voltage: DC 0.5ml x 33V Maximum output current: 7A Maximum output power: 80W long continuous work, please strengthen heat dissipation, preferably leaving a surplus Conversion efficiency: 91% (measured under 12V input, 19V output 2A) Note: this module is a regulator module, without constant current function, and cannot be directly exported to a battery or LED (i.e. output cannot be directly connected to a battery, e.g. battery itself can be connected with a charging circuit), e.g. red charging treasure, LED drive is ok) Key functional details: Press and loosen quickly (press for less than 0.5 seconds) to switch the display input and output voltage, the indicator is red when the input voltage is green, and the output voltage is pressed to close the display button for about 1 to 2 seconds, then release and press the button again to reopen the display. Press this button for more than 2 seconds, release the reference voltage reference, then defaultly display 3.33 and the red light flicker, which means that the input is more accurate, and a short press on the button can change the value, ranging from 3.28 to 3.38.Press the button to change the value, press the button for more than 1 second to adjust it to the appropriate value, save the reference set, then press the button to change the value, reference voltage and return to normal display.(Tip: adjust the reference voltage when the display voltage is lower than the actual voltage and the reference voltage when the display voltage is higher than the actual voltage. Warm tip: the power supply module must work properly. the natural cooling power of the module is about 60W, such as 80W, which requires appropriate heat dissipation measures, or it will cause overheating protection.In the case of large currents, it is normal to have an inductive sound. Size: 7.8x4.7 cm/3.07x1.85inch Notes: Allow error of 1-3 mm due to manual measurement.Please make sure you don't mind bidding The picture may not reflect the actual color of the project due to differences between different monitors.Thank you! The package includes: 1 lift and pressure relief regulator module
