Product Description
5A high-power 75W DC-DC adjustable buck-stabilized power supply module with voltmeter display
I1. t uses original genuine upgraded chips, superior to similar products regarding input and output voltage range, power, and efficiency. The power can reach 75W, and it has a very high-cost performance.
Module features:
1.5A high power, high efficiency, step-down and low ripple;
2. With power indicator light;
3. The materials and workmanship are sufficient, and there are no cutting corners to reduce capacitance and inductance, which will affect product performance!
2. Module performance and features:
1. Equipped with a power indicator light and voltmeter display, and the voltmeter can be self-calibrated. Using a more advanced voltage microprocessor, the voltmeter has an error of ±0.1V and a measurement range of 0~40V. (Note: For the voltmeter to work properly, please ensure that the input voltage is above 3.5V)
2. Touch the button to switch between measuring input or output voltage. The LED indicator light shows which voltage value is being measured. You can save and remember which voltage is currently displayed. Long press the button to turn off the voltmeter display.
3. Input voltage 4.0~38V. (The input voltage must be more than 1.5v higher than the output voltage)
(a). The adjustable output voltage range is continuously adjustable from 1.25V to 36V. (The input voltage must be 1.5V higher than the output voltage)
(b). The output power can reach 75W. The output current can reach 5A, and it is recommended to use it within 4.5A (Note: Please add a heat sink to the power chip when using it at high power).
(c). High conversion efficiency, up to 96% (efficiency is related to input and output voltage, current, and voltage difference)
(d). Load regulation rate S (I) ≤ 0.8%, voltage regulation rate S (u) ≤ 0.8%
(e). With overheating protection and short circuit protection function
4. Size 66*40*12MM
5. Weight 28g
Application scope:
1. This module can be used in voltage reduction fields where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V vehicle laptop power supplies, industrial equipment voltage reduction, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
