XL4015E 5A 75W DC-DC Adjustable Step-Down Module Regulated Power Supply Module With Voltage Display

XL4015E 5A 75W DC-DC Adjustable Step-Down Module Regulated Power Supply Module With Voltage Display Module performance and features: 1. With voltmeter display and voltmeter can be self-calibrating, using a more advanced voltage microprocessor, voltmeter error 0.05V, range 0-40V (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V) 2. With power indicator, touching the button to switch the measurement of input or output voltage, and there is an indicator to show which voltage is being measured, and save the settings, even if the power is off and on again 3. Voltmeter can be turned off, when not needed when touching the left button can be easily realized 4. With terminal block, easy to use without soldering iron, and retain the soldering wire junction point 5. Input voltage 4.0-38V (input voltage must be higher than output voltage by more than 1.5V) 6. Adjustable output voltage range 1.25V-36V continuously adjustable (input voltage must be 1.5V higher than output voltage) 7. Output current up to 5A, it is recommended to use within 4.5A 8. Output power up to 75W, more than 50W, please strengthen the chip cooling (that is, must add a small heat sink) 9. High conversion efficiency, up to 96% (efficiency and input and output voltage, current, pressure difference) 10. Operating frequency: 180KHZ 11. Load adjustment rate S (I) less than 0.8 percent, voltage adjustment rate S (u) less than 0.8 percent 12. With thermal protection and short-circuit protection (but short-circuit there is an accident, try not to short-circuit) 13. Board size: about 7 x 4.7 cm Applications: DCDC step-down module is used in the field of input voltage higher than the output voltage step-down, such as batteries, power transformers, DIY adjustable voltage regulator power supply, LCD monitors and LCD TVs, portable instrument power supply, telecomnetwork equipment, 24V car laptop power supply, industrial equipment step-down, 12V step-down to 3.3V, 12V step-down to 5V, 24V step-down to 5V, 24V step-dow
