DC UPS 12V 12W UPS uninterruptible power supply control board, used
to design routers, switches and other network equipment or infrared
alarms for continuous power supply. When the battery is full, the
upper limit can output 1A current. When the battery voltage is
about to be empty, it can output 8-9W Power, when the output is
short-circuited, it will automatically shut down, and it will be
restored after recharging. Before the battery is emptied and shut
down, there will be a flashing prompt. After flashing several
times, it will enter the low-power protection and turn off the
output! (Reminder: The input or output interface can share the
negative electrode, the positive electrode cannot be shared, and
the battery terminal cannot share the negative electrode!)
Reminder: The current motherboard has a charging time detection
function. The default slow charge is suitable for batteries within
8Ah. When the jumper is changed to fast charging, it is suitable
for batteries within 8-15Ah.
The high-power UPS uninterruptible power supply motherboard
developed for 12V 1.5A routers or optical modems can also be used
for 12V 1A equipment!
When charging, a minimum input of 5V is required, and the default
charging current is 0.5-0.6A. You don’t need to replace the
customer’s original charger. There is also a jumper to increase the
charging speed. If the charging is accelerated, the customer’s
original power supply must be replaced to prevent potential safety
hazards. Double the power. For example, if the customer is using a
12V 1.5A power supply, if you charge quickly, you need to change to
a 12V 2.5A-3A power supply. You need to keep more margin, because
you have no way to know whether the quality of the power supply is
up to standard. ! Please pay attention to this problem!
Product description:
Input voltage: DC 5V-12V (this voltage is the voltage when charging
the battery)
Output voltage: DC 9V or DC 12V can be selected (default is 9V, you
can also change the jumper to set to 12V, and the output voltage is
the voltage when only battery power is used, if there is a charging
input, the output will be equal to the input)
Output power: MAX 12W
Board size: 50*20*6mm
BAT connection is the last step before connecting the battery. This
is very important. Battery 3.7V lithium battery or polymer battery,
battery capacity: 1-3AH (MAX 5AH)
