JL-251/252/253 NEMA Interface Twist Lock Smart Light Controller (DALI dimming)

Product Description

The JL-251/252/253 series of twist lock smart light controllers are suitable for independently controlling adjustable LED street lights (DAIL dimming) based on the natural lighting level of the environment. They can be used in municipal roads, park lighting, landscape lighting, etc.
This series of products uses a microprocessor circuit design with an infrared filter photosensitive tube. It provides heavy surge arresters (MOV) to protect the lamp from surge current and lightning strikes.

In addition, a 10-second delay control function can be set to avoid excessive operation due to spotlights or lightning at night.

This series of products can maintain constant and reliable characteristics, and the relay can exceed 10,000 working life cycles. When equipped with a double-layer protective shell, it can provide a longer working life for the JL-251/252/253 series of products.
This series of products provides locking terminals that meet the requirements of ANSI C136.41, and also meet the standard requirements of ANSI/UL773 for the use of plug-in and twist lock light controllers in regional lighting.

Operation Instructions Diagram
According to the environmental lighting level, the lighting output of the controlled LED lamp is adaptively adjusted to ensure a uniform lighting environment in the jurisdiction area. When the natural lighting level reaches 110% of the rated value, the controlled lamp will automatically turn off, as shown in the process of switching from the red line to zero output below.

Installation Instructions
Push the photoelectric controller up and rotate it clockwise to lock it into the socket.
If necessary, adjust the position of the socket to ensure that the light-sensing port points to the north direction indicated by the top triangle of the light controller.

Initial Testing
· During initial installation, it usually takes several minutes for the light controller to turn off.
· To test “on” during the day, cover the light-sensing window with opaque material.
· Do not cover with your fingers, as the light passing through your fingers may be enough to turn off the light control device.
· The light controller test takes about 2 minutes.
*The operation of this light controller is not affected by weather, humidity, or temperature changes.
