1. High efficiency

XTP-12 has the leading technology of MPPT function (acquiring national patent), the system can get the overall efficiency of 96%, which is 15%--30% higher than the systems without this feature;

 

2. Independent Voltage-stabilization

DC-DC solar power system can independently stabilize the voltage  (instead of relying on batteries to regulate), the system can work with disconnection to battery banks, which greatly enhances the reliability and makes battery maintenance and repair easy;

3. Wireless Control Mode.

Its radio frequency is 433MHz, its transmitting power is below 10mW and its control range is below 150 m. The radio frequency and intensity are in line with the relevant regulation by the national and provincial commissions for radio management. The system has the strong electro counter-counter capability; and the environmental electromagnetic interference is negligible;

 

4. It has signals of four-direction and six-lane phases and can be integrated with eight three-phase crosswalk lights. There are also twenty options for time intervals and 49 combinations of signals;

 

5. The interval between green light and red light is continuously adjustable from 0 second to 250 seconds. The duration of green flash, yellow flash, yellow light in four directions and red lights in four directions are adjustable from 0 second to 15 seconds;

 

6. The display procedure for signals is: green→green, flash→yellow→red in 4 directions. Users can also set the procedure and combination as per their need;

 

7. Manual - Automatic Control, Green Flash Control, Yellow Flash and Timing On / Off;

 

8. Under-voltage Protection (automatic shutdown as battery voltage is below 11V). It can also output yellow flash signal as per users’ requirements;

 

9. Automatic Restart after restoration of voltage (re-boot automatically with battery voltage at 12.5v);

 

10. Temperature Compensation (intelligent battery charging mode corresponding to the charging curve at different temperatures);

 

11. Extend lamps’ lifespan maximally with temperature-compensated, constant-current and stable-voltage power supply to LED;

 

12. System Reset (anti-crash);

 

13. Automatic Restoration of re-send and receive time-out errors;

 

14. Data Protection at power failure (≮8 years);

 

15. The system can be connected to the upper computer through RS232 communication port or have wireless access to the upper computer through the duplex wireless module at the serial RS232 port, so as to realize the central management.
