Vehicle UPS
The UPS is high-end backup power which designed for vehicle MDVR products.
The input section uses a lithium iron phosphate battery and special charge management IC;
and it uses the high efficiency DC-DC buck-boost switching circuit.
In order to achieve accurate voltage overshoot, over-discharge voltage,
current overload and short circuit protection it uses a battery cell Protection control circuit.
Rated input voltage is 8 ~ 36V DC. When the supply voltage of vehicle MDVR is less than 9V or
unexpected power failure the vehicle MDVR will automatically switch to UPS.
Caution:MDVR will work five minutes default after the vehicle keys close,
if customers want to lengthen working hours after power failure,
please change the delay time on the DATE&TIME interface of MDVR.
IC control technology and multiple protection circuit;
High-efficiency current output, high-capacity branded lithium battery;
Friendly and easy to install;
Special vehicle power supply input and output ports;
All-metal shell design for vandal proof;
Long battery life, outstanding high temperature durability, no memory effect and Environmentally Friendly;
