1.  

   1. Support simultaneous charging of 50 tablet personal computers; overall dimension is length*height*thickness: 640*1000*390mm;

    

   2. The main body is made of 1.0-1.5mm cold rolled sheet and some parts are made of 2.0 cold rolled sheet with reasonable match of silver and black;

    

   3. The USB interface of circuit board is adopted for charging to avoid damage to equipment caused by excess instantaneous current;

    

   4. The handrail is designer according to ergonomics and made of elliptic stainless steel pipe and rubber sleeve which is beautiful, practical and not freezing to the hand; both sides of the cabinet are designed by acrylic LED lamps to display the charging state of each tablet personal computer;

    

   5. The upper and lower decorative sheet in front of the charging cabinet and the right and left doors are of arc design to greatly reduce bump to teachers and students; there are air ports for the right and left doors and maintenance door to effectively discharge the hot air in the cabinet;

    

   6. There are ABS engineering plastic interlayers set in the cabinet to put the tablet personal computers in different interlayers and effectively avoid scratch to tablet personal computers;

    

   7. There are multiple protection measures of high-voltage strong current insurance and leakage protector for power switch to ensure personal safety of users;

    

   8. The semiconductor chips of first-level manufacturer in American are adopted for all power modules to realize small size, low heart radiation and optimum power design, and various types of protection functions are added which conforms to ROHS to realize the maximum charging current for each USB, LED display for charging, protection functions such as built-in over-voltage and over-current; the input range of voltage: 100-250V, rated output power: 720W;

    

   9. The rated output voltage and current of each USB are 5V and 2.4A; each USB supports over-current protection: all current greater than 2.4A is limited to 2.4A to ensure normal operation of the powered equipment; when the powered equipment is abnormal and the voltage of corresponding USB port is greater than 5V, the circuit can block output and reverse perfusion to ensure normal operation of other USB ports; when short circuit occurs, limit the current and lighten the warning LED;

    

   10. The LED light is yellow during charging process, green when fully charged and in standby and red for abnormal protection. Input under-voltage protection and over-current protection.

    

   11. The bottom of the cabinet is furnished with high-quality, super-silent and damping omni-directional wheel and braking wheel to facilitate movement and utilization of the cabinet;
