PH1504 Light-controlled Switch

Product Overview

Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, PH1504 Light-controlled Switch is designed for automatic ON/OFF control of lighting systems by detecting ambient light intensity. When the surrounding environment becomes dark, the switch can automatically turn on the connected lighting load; when daylight is sufficient, it can turn off the circuit to reduce unnecessary power consumption.​

PH1504 is suitable for outdoor lighting projects that require stable light sensing, reliable switching and long-term operation under changing weather conditions. With adjustable ambient light sensitivity, electricians can set the control point according to different installation environments and project requirements.​

The product supports 25A rated current and wide operating temperature, making it suitable for street lights, garden lights, road lighting, public facility lighting and commercial outdoor lighting control systems.​

Main Features

1. Automatic light sensing control: PH1504 detects ambient brightness and automatically controls the lighting circuit according to day and night changes.​

2. Adjustable light sensitivity: The ambient light control range of <5–50LUX allows flexible adjustment for different outdoor lighting environments.​

3. 25A rated current: The product supports higher lighting load control, making it suitable for street lamps, public lighting and outdoor lighting circuits.​

4. Wide voltage adaptability: Supports AC/DC wide voltage input options, helping the product adapt to different power supply systems and project requirements.​

5. Wide temperature operation: With an operating temperature range of -40°C to +70°C, PH1504 is suitable for outdoor environments with large temperature changes.​

6. 4KV lightning protection: Built-in lightning protection design improves product reliability in outdoor electrical installations.​

7. Easy installation: Compact structure and simple wiring design allow fast installation in lighting fixtures, poles, control boxes and outdoor lighting systems.​
