product introduction:
The maximum output current is 3A , the long-term operation is 2.1A, and the margin is sufficient.
With a new design , the circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitors have a short life and tantalum capacitors have the risk of explosion). 3 large solid ceramic capacitors (MCC) used in high-end circuits are now used .
Ripple is very low, 12V to 5V 3A is only about 10 millivolts, many of the ripples in the industry have reached 500 millivolts or greater, which will cause an invisible damage to the equipment, and will seriously cause the equipment to work abnormally or be damaged. IPHONE is Very precious .
The new scheme uses synchronous rectification , and the circuit conversion efficiency is very high. The efficiency is as high as 97.5% when 6.5V to 5V 0.7A, and 94% when 12V to 5V 1A, unlike some peers, the efficiency is only 60-70%. (The efficiency test removes the voltage drop of the reverse input protection diode and fuse).
Use flat copper wire inductors to maximize conversion efficiency. Reduce heat.
The first in the whole network with output overvoltage protection function , the input has a 1.5A fuse, and the output 5V has 300W TVS tube for overvoltage clamping protection to protect USB devices.
At present, there is no overvoltage protection function for the USB buck modules in the same industry, and there is a very big security risk to the USB device. If you think about the breakdown of the buck module, 12V is directly added to your IPHONE. Will your IPHONE survive?
Using the latest USB recognition circuit, it is perfectly compatible with IPHONE, most Android phones, and IPAD .
The short-end gold-plated endless USB has a long service life, which is far from that of ordinary USB interfaces.
Output voltage indicator ( red )
The input is provided with a reverse connection protection diode , and the positive and negative poles of the input will not be damaged if it is reversed. (Our test efficiency ignores the voltage drop of the input diode and the fuse)
Ultra-low quiescent current, quiescent current 0.85 mA . There is no need to add a switch to the car battery
 Module parameters
Module nature: non-isolated buck module (BUCK) synchronous rectification
Input voltage: DC 6-24 V
Output voltage: 5.1-5.2V
Output current: maximum 3 A (please pay attention to heat dissipation at full load), the actual test input 12V output within 2A without special treatment heat dissipation
Conversion efficiency: up to 97.5% (6.5 to 5V 0.7A) (test value after short-circuit reverse connection protection and fuse)    |

Exchange or return policy
Every item comes with a 30-day warranty. However, there are certain conditions that apply:
-
The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).
-
The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).
-
The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.
Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:
- Provide a detailed description of the damaged item(s).
- Mention any tests or experiments conducted by the customer.
Please note that the store reserves the right to make the final decision regarding product replacement or refund.
