GW2-2 Sonnen drahtlose Ampel

The Handheld remote controller just likes your mobile phone which is very easy to take and set the programme, our solar wireless traffic light will help you save many cost of external wiring, trenching and maintenance.The whole cost of the solar wireless traffic system will be cheaper than the normal AC traffic one The solar panels mounted at the top of the traffic lights can generate unstable DC photovoltaic electicity. When the current is delivered to the controller and go through the chopper, photovoltaic power will be turned into pulse and delivered to the setting circuit of voltage and current. The SCM CPU, according to the state of battery charge and load current feedbacked from the parameter sampling circuit, will adjust the frequency and width of the pulse as per the preset procedure, so as to make the output voltage and current meet the demands of load and battery. XTP-12A Solar Traffic Controller System has the following characteristics: 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 diconnection 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-couter 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 contiuously 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 maximumly 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.
