DESCRIPTION
The Electronic Street Light Control System has the provision to control the street lighting/yard lighting/quarry lighting system automatically as per the timings programmed in the system and the programs can be modified automatically throughout the year as per the seasonal changes which is an already programmed in the system.
SPECIFICATIONS & FEATURES
1. Real-time clock display and facility for setting through Front Panel
2. Battery backup for real-time clock for minimum 2 years
3. Controlling the load up to 10 kW
4. Automatic and manual modes to enable the user to switch on any time
5. LCD to display time, date, month and day continuously
6. Protection against any spikes from power surges
7. Withstand wide input variation of 190-250 V
8. ON/OFF within +/- 1 minute, with respect to time set in the memory
9. Protection from temperature variation of 0 deg. C to 70 deg. C
10. Provision of high current sensing and tripping automatically when there is 11. excess current in the load path and restore automatically after release of the excess current
11. Stand by power consumption of the system is less than 1 watt
Provision of high voltage sensing and will disconnect the lighting load within 20milli seconds automatically and restores automatically after the normal voltage restoration
Controlled by 2 micro controllers and does the supervisory function, even if one micro controller does not function because of power surges
Real-time clock has 9V backup built in battery which is set and will maintain the clock accurately even in the continues power failure conditions
If the voltage is more than 250 Volts and less than 190 Volts, the lights will be switched off automatically to protect the lights from voltage fluctuations
System will switch ON automatically after the voltage is restored to normal voltage
