Time Based Load Controller Street Light Controller Module

The eSaver Digital Time Based Load Controller is a smart energy-saving solution designed for street lights, outdoor lighting, and electrical load management. Built with a microcontroller-based system and precision RTC (Real-Time Clock), it provides accurate and reliable automatic ON/OFF switching based on user-defined schedules.

? Key Features:

Programmable Timer Switch – Set up to 4 independent alarms, each with ON & OFF scheduling for flexible load control.

Dual Operation Modes – Choose between automatic timer control or manual ON/OFF switching with the press of a button.

Big Display – A 0.5” 7-segment LED display that auto-blanks after 3 seconds to reduce power (Optional) consumption.

User-Friendly Controls – Simple 3-button interface for time settings and alarm programming.

High Load Capacity – Supports 230V, up to 7A (~1250W) electrical loads, suitable for street lights, appliances, and industrial applications., Also 20A & 30A relay versions are available.  

Safety & Flexibility – Prevents false triggering by allowing unused alarms to be set at 00:00.

⚙️ How It Works:

On power-up, the controller briefly shows the real-time clock before entering power-saving mode.

Automatic Mode: Street lights or connected loads switch ON/OFF automatically as per the scheduled alarms.

Manual Mode: Instantly power the load ON/OFF using the SW2 button.

Easy time and alarm setup ensures hassle-free operation for both residential and commercial applications.

? Ideal Applications:

Street Light Timer Controller

Outdoor Lighting Automation

Home & Office Electrical Load Control

Industrial Power Saving Systems

Timer Switch for Appliances & Pumps

? Features:

Programmable timer-based power saving device.

Microcontroller-based system with precision RTC.

0.5” 7-segment, 4-digit LED display.

Supports 4 individual alarms, each with ON & OFF control.

3-button switch interface for settings.

Handles 230V, up to 7A (~1250W) load. 20A & 30A Relay Versions.

Supports automatic timer switching and manual ON/OFF operation.

⚙️ Working Principle:

On power-up, the time is shown for 3 seconds, then display goes blank to save energy (Optional).

SW3 button:

Press once → display time briefly.

Press twice → enable continuous time display.

? Modes of Operation:
1. Automatic Timer ON/OFF:

Load switches ON/OFF according to programmed alarm schedules.

Supports 4 alarm pairs (AL1–AL4).

2. Manual Switching:

SW2 button directly powers the load ON or OFF.

⏰ Time Setting Procedure:

Hold SW1 for 3 sec during power-up → display shows “tSEt”.

Hour (HH) blinks → adjust with SW2 (UP) / SW3 (DOWN).

Save hour with SW1, then Minute (MM) blinks.

Adjust minutes with SW2 / SW3.

Save with SW1 to exit.

⏰ Alarm Setting (AL1–AL4):

Press SW1 repeatedly to select desired alarm (ALx).

ON Time Setup:

From ALx, press SW2 → display shows “ON” → current ON time appears.

Adjust Hour/Minute (SW2/SW3) → Save with SW1.

OFF Time Setup:

From ALx, press SW3 → display shows “OFF” → current OFF time appears.

Adjust Hour/Minute (SW2/SW3) → Save with SW1.

Move to next alarm or exit to time display.

⚠️ Note: If an alarm is not needed, set both ON & OFF times to 00:00 to avoid false triggering.
