Sound Familiar?
Problems with Conventional Street Light Timers
Streetlights ON at noon — no one notices until next day
Fixed timer drifts over months — wrong ON/OFF times in summer vs winter
Blown lamp stays dark for weeks — no one reports it
No idea how much each circuit is consuming
High electricity bill with no way to verify the reading
Cannot turn on lights during festivals or emergencies remotely
The CD-SL-STL replaces all of this with intelligent, connected control.
Simple & Reliable
How the CD-SL-STL Works
→
🌅
STEP 01
Astronomical Clock
Built-in GPS computes exact sunset and sunrise times for your location every day. No drift, no manual updates.
→
💡
STEP 02
Lights Turn ON & Dim
At sunset all circuits energize. Dimming schedule reduces brightness at midnight or custom schedules.
→
📊
STEP 03
Energy Monitored
Per-circuit kWh, current and power factor logged continuously. Lamp failure detected by current drop.
📱
STEP 04
You Stay in Control
Cloud dashboard and mobile app show live status for all circuits. Override, dim, or alert remotely.
Built-In
Key Features
Astronomical Timer
Auto ON at sunset, OFF at sunrise — calculated daily from GPS latitude/longitude. No manual calendar needed.
PWM Dimming 0–100%
Smooth dimming of LED streetlights over 0-10V or DALI interface. Set dimming schedules (e.g. 100% till midnight, 50% after).
Lamp Failure Detection
Monitors current on each circuit. Instantly detects and reports blown lamps or tripped MCBs. No more dark streets going unnoticed.
4G Cloud Dashboard
Monitor all poles and circuits from a browser or mobile app. Live ON/OFF status, energy data, and alarm history.
Flexible Scheduling
Up to 8 time slots per day with independent dimming levels. Override for festivals, emergencies, or maintenance.
Alerts & Notifications
SMS + push alerts for lamp failure, phase failure, power theft, MCB trip, and device offline events.
OTA Firmware Update
Push logic and schedule updates remotely. Update dimming profiles and schedules across hundreds of poles at once.
Energy Metering
Per-circuit kWh logging with monthly reports. Proves energy savings vs old sodium/CFL fixtures. Tamper detection.
