Automobile DC UPS Power System Temp Test Report

Special Description 1: Automobile internal by too Sun penetrating sunshine and car is confined does not ventilation environment, so will produced sunshine warming effect, in outdoor temperature up to 36 °C, car within temperature by long time sunshine warming, car within will up to 60~65 °C, Sunshine direct location will up to 65~70 °C around, but as long as Sun sunshine no irradiation to of location, temperature will slightly below car within temperature about up 55~63 °C around.

Special description 2: IO-Power USMC-12V0712-II series online type does not interrupted operation power system, due to should car within environment of special high temperature requirements, used resistance high temperature roast paint package covered metal shell, in outdoor temperature up to 36 °C, car within temperature by long time sunshine warming, car within will up to 60~65 °C, in Sunshine direct products shell surface situation, shell surface temperature about 65 °C, shell within temperature about 55~58 °C, C-LiFePO4 Lithium Batteries temperature about 50~55 °C ; IOP-USMC-12V0712-II products, AM 10:00~ PM 4:00 under sunshine temperature test for a long time in the morning, all features of normal operation and provide stable DC 11.5V~14.4V+-3% power to the cameras inside and outside the normal operation of the car.

Outdoor DC UPS Power System Output 12VDC Transmit Distance Test

+ x12 = 20 meter

Test 1 : Non Charging Output Power Voltage 13.20V ----20 meter ---->13.19V

DC 13.19V Power Supply for IP Camera working test OK (Pass)

+ x22 = 38 meter

Test 2 : Non Charging Output Power Voltage 13.30V ----38 meter ---->13.26V

( 13.30V ---->20 meter @13.29V---->38 meter @13.26V )

DC 13.26V Power Supply for IP Camera working test OK (Pass)

No.	Battery Voltage	Transformers No Power Supply	Transformers Power Supply	Camera No Power Supply	Camera Power Supply	1.5M	47M 1.5+45 +0.5=47	55M 1.5+45 +1.5*5+1=55	63M 1.5+45 +1.5*10+1.5=63	71M 1.5+45 +1.5*15+2=71
Measuring Voltage	13.3V	￭		￭		13.3V	13.3V	13.29V	13.29V	13.28V
DC voltage difference distance less than the AC voltage difference from many (Consistent with the theory of electricity)

Camera Operation						OK	OK	OK	OK	OK
Recommended 1:12VDC power supply within distance to 50M is good. Recommended 2 distance after over 50M: 12VDC power supply, voltage after voltage drop is less than 12.3V, but because most of the cameras are operating within the range of 9V~16V, therefore can also be functioning properly.
