Product Summary
The dimming photocontrol JL-252 is designed to automatically control dimmable LED street lighting (DALI) in accordance with ambient natural lighting levels. This advanced product features microprocessor circuits with an IR-filtered phototransistor for precise light detection.
A heavy-duty surge arrester (MOV) protects the lamp from inrush current and lightning impulses. The built-in 10-second time-delay prevents excessive operation caused by spotlights or lightning during nighttime hours.
With a relay rated for over 10,000 cycles, this product delivers constant reliability. When used with the optional sandwich cover, it offers extended operational life. The twist lock terminals meet ANSI C136.41 requirements and are UL listed under ANSI/UL773 standards.
