UPS uninterrupted power control motherboard DC12V/15V red board 24W1A UPS power supply module 2s V4.0cn

Regarding power: The peak power of this product is 30W (test when the battery is full, only 3-5 seconds are allowed), and the rated power is 24W (when the battery power is greater than 50%, it can be tested.The value of the valley value is 18W (the battery is tested when the battery is about to be exhausted, and this power is allowed for a long time). Since the battery cannot be fully used in the use of the battery, the user can only useWhat is the label on the device, but the actual power cannot exceed 18W, otherwise there is a risk of overheating and restarting. As for the 24W power, it can only be used for a few minutes or tens of minutes when the battery is full, but this power cannot be used for a long time!Unless you hang an additional temperature control fan to cool the motherboard, if you heat dissipate well, you can continue to load 24W power for a long time!

Regarding the fever: When the battery is fully charged at 18W, the heat is 60-70 degrees, the heat is 70-80 degrees when the battery remains half, and the heat is 80-90 degrees when the battery is exhausted.-80 degrees, when the battery power is less than 50%, the load 24W will cause the chip to exceed 90 degrees, and then trigger overheating protection. The chip is restarted repeatedly. As a result, it is easy to damage. Do not use it overload!

Method about determining whether it is overloaded: After connecting the load after power -on, the high -temperature area of ​​the back of the motherboard is touched by your finger. If you can withstand more than half a minute, it means that it is not overload!

Regarding the input current: For non-professional users, the input current must be greater than 12V3A. The 4-5A current is better. When leaving more margins, it can reduce the temperature of the external power supply. For professional-level users, there is no need to pay attention to this parameter.Ensure that external power supply power is greater than charging+loads. For example, the load is 0.5A, the charging is 0.5A, and the external power supply is enough to connect 12V 1.5A! Novice does not understand this, so you must refer to the provisions of the use of the use, otherwise you will encounter various each.An annoying question!

Note: The downgrade version is a version derived from the power of the 24W standard version to reduce the power of the charging and battery protection components. This version of the rated power is 18W. Naturally, it can be used for about 12W when heat dissipation.Treatment of heat dissipation, the main board is small, and your own heat dissipation cannot be reached! So pay attention to the load power!

The downgrade version charging is about 0.5A!
