Product Description

JL-252 Twist-Lock Intelligent Photocontrol DALI, Constant illumination, Midnight night

Product Summary

The dimming photocontrol JL-252 is applicable to control the dimmable LED street lighting (DALI) automatically in accordance with the ambient natural lighting level.

This product is designed with microprocessor circuits with IR-filtered phototransistor. 

A heavy duty surge arrester (MOV) is provided to protect the lamp from inrush current as well as impulse by lightening.

Further, a preset 10 seconds time-delay prevents excessive operation due to spotlight or lightning during the night time.

It provides constant reliability as the relay has sufficient work life of over 10,000 cycles, and offers extra long work life when a sandwich cover option is applied together.

This product provides twist lock terminals meeting the requirements of ANSI C136.41 as well as being listed by UL under the Standard for Plug-In, Locking Type Photocontrols for Use with Area Lighting ANSI/UL773.
