Photocell devices Vs SWADEEP-02 EC

NATURE SWITCH BASED SWADEEP IS NOT A PHOTOCELL
• The sensor is sensitive to infrared spectrum- so immune.
• The sensor exhibits a calibration stability over time/temp.
• The sensor is a silicon semiconductor and not an LDR.
• The sensor operates over - 40 deg to + 150 deg.
• A cabinet meeting IP 65 avoids the effect of dust and rain.
• Dust will not settle on the window due to design features.
• Clouds will not make it err due to calibration stability.


Timers Vs SWADEEP 02 EC
The sunrise and sunset time keeps changing in a year.
• Weather influences the visibility in a dynamic way.
• A timer can not adjust to this dynamic change on it’s own.
• So needs resetting and so semi automatic in reality.
• The RTC is prone to errors and drifts and needs correction.
• The operator needs a particular level of skill to set/reset.
• The presently available models can not with stand high voltages.
• The memory back up is not robust at the moment.
• The users see an inevitable need to maintain the timers.
• SWADEEP switch adjusts to the natural changes on its own.
• Do not call for any settings/ changes/ maintenance.
Timers


Value to the End User
The energy saving potential per day is estimated at 1.5 hrs per day.
The energy saving per kW of load per day will be 1.5 units.
Assuming an average load of 5kW in street lighting saving = 7.5 units/day.
Assuming a tariff rate of Rs. 4 per unit the saving is worth Rs. 30 per day.
So the saving per year will be Rs.30 x 365 days = Rs.10,950.
If the wastage per day is 2 hours the saving per year will be Rs. 14,600
If the wastage per day is 3 hours the saving per year will be Rs. 21,900
PAY BACK PERIOD : 6 months to 18 months depending on model.

Additional advantages:
The saving in manual switching cost per switch per year will be Rs. 2,000
The lamp life will be enhanced due to automatic over voltage trip feature.
Public will appreciate the timely switching ON of the street lighting.
Public will appreciate the timely switching OFF of the street lighting.
No more public complaints and staffing and manning problems.
Assured switching on a rainy day and in winter and fog.
Reliable MCB based over load protection.
Shock proof enclosure to protect animals and children.
