Product Use Instructions
External power input description
IOP-USSS-12V3556-OA series uses solar cell DC power input, voltage ranged DC 15V~28V with
DC current 8A Max. The suitable solar panels are ranged 40W~120W/4~8.5A. The PCBA execute
battery charging and discharging management. At the same time, it provides DC 11.5V~DC 14.4V
to the load devices, such as surveillance cameras, DVR/NVR host, infrared projector……etc.
DC power output description
IOP-USSS-12V3556-OA series, built-in charge and discharge physical circuit element controller,
adopts on-line uninterruptible circuit design, online real-time discharge through iron lithium battery,
provides DC 11V ~ DC 14.4V power to load equipment , Such as surveillance cameras, DVR / NVR
hosts, infrared projectors, etc.
When the iron lithium battery is discharged to 11V + -3%, the built-in charge and discharge
physical circuit element controller will automatically perform low-voltage stop discharge protection.
The final protection discharge voltage of this series of products is 9V + -3%, and the maximum
discharge protection voltage is 14.4 V + -3%.

instruction
IOP-USSS-12V3556-OA series, built-in charge and discharge physical circuit element controller.
When the lithium iron battery discharge reaches 11V + -3%, it will start the low voltage stop
discharge protection, and restore the external power input after DC power charging. The processing
controller will wait for the voltage of the C-LiFePO4 Lithium battery to rise to 12.8V + -3% before
discharging the load. (It usually takes 10 ~ 30 minutes, depending on the charging current)
C-LiFePO4 Lithium Batteries charging
IOP-USSS-12V3556-OA series adopts the latest technologies of high and low temperature
resistance of C-LiFePO4 Lithium Batteries. It is very different from the other types of battery, like
lead-acid batteries, deep cycle lead-acid batteries, and lithium ion battery characteristics. Besides,
the different C-LiFePO4 Lithium Batteries products characteristics made by different manufacturers
are also different both in voltage and current.
