AU-X300

The AutronX AU-X300 is a light-dependent resistor (LDR) sensor timer designed to automate lighting control based on ambient light levels. With an adjustable sensing range of 5–500 LUX, it triggers connected loads like lamps or streetlights to switch on or off depending on light intensity.

Featuring a built-in timer (1–9 hours), the AU-X300 ensures efficient energy usage by controlling light operation duration. Its robust design is suitable for outdoor applications such as garden lighting, signboards, and township street lights, providing seamless day/night automation.

Troubleshooting & FAQs

1
Why doesn’t the load activate during testing?

Cover the sensor with a black polythene to simulate low light; ensure settings are correct.

2
How does the timer function work?
Once triggered, the load will stay ON for the set time (1–9 hours), then switch off.
3
Can the timer reset if power is interrupted?
Yes, a power cut over 2–5 seconds resets the timer.
4
Can it be used under direct lighting fixtures?
No, avoid installing the photocell where light directly irradiates the sensor.
5
What is the maximum load capacity?
Supports up to 10 Amp load for connected lighting systems.
