🌗 Day Night Sensor – Photocell 3 (20 Amp)
Model No.: 1L-PC03
The 1LPC-03 – 20 Amp Day/Night LDR Sensor is a rugged, high-performance lighting control solution designed to automatically turn lights ON at dusk and OFF at dawn based on ambient light levels. With weatherproof construction and a powerful 20 Amp switching capacity, it’s ideal for outdoor, industrial, and high-load applications.
This sensor helps you reduce energy consumption, increase lighting efficiency, and eliminate the need for manual switching—making it both convenient and highly practical for a variety of installations.
📦 Description
The 1L-PC03 uses a photoresistor (LDR) that senses ambient light levels and switches lighting loads accordingly. It operates on the principle of semiconductor photoconductivity—where incoming photons reduce resistance, allowing current flow to trigger switching.
This model includes a remote sensor with a separate control unit, offering more flexibility in installation and precise light detection even in shaded or hard-to-reach areas.
