ZU15 1. General This specification defines the performance characteristic of an DC/DC Car charger. Car charger must comply with all the requirements of the specifications and drawing herein. . 2. Electrical Performance and Tests 2.1 Input Rated input voltage: Vdc 12V Frequency: N/A Current: 2500mAmax@ 12Vdc Standby power: < 0.1W Rating input load power: 27Wmax. Starting time: < 1S@ 12Vdc Io = 100% load 2.2 Output Voltage: 5.0V ± 5% Current: Smart 4.8A max. for Iusb1+ Iusb2. Ripple & noise: 120mVP-Pmax @ full load Note: 20MHz bandwidth ripple & noise is measured by using 0.1uF C.C . & 10uF E.C. bypassed at the output connector. 2.3 Short circuit protection No damage to this power supply when output shorted to ground. When the short-circuited is removed, the adapter shall promptly recover its normal operation. 3. Mechanical Tests and Requirements 3.1 Drop test Drop height: 1.0m above 50mm hardwood. Method: Total 6 times. Drop one time for each of the 6 case surfaces. Expected result: After drop test, the unit should still operate properly. Small nick or slight deformation may be accepted. 4. Environmental Conditions 4.1 Operating temperature 0°C ~ +40°C 4.2 Storage temperature -20°C ~ +60°C 4.3 Humidity 90% RH Non-condensing 5.
