Key Features of LT100 Intelligent Dimming Photo Controller

Smart Dimming Control

Supports both 0-10V and DALI midnight dimming, helping reduce energy consumption and light pollution during low-traffic nighttime hours.

ANSI & UL Compliant

Designed according to ANSI C136.41 and UL773 standards for reliable compatibility with outdoor lighting systems.

Wide Voltage Compatibility

Operates with 120-277VAC input voltage and remains functional down to 85VAC, suitable for various global lighting applications.

Heavy-Duty Surge Protection

Built-in 640 Joules MOV surge protection (upgradeable to 1280J) helps protect lighting systems from voltage spikes and harsh outdoor environments.

Zero-Crossing Technology

Integrated Zero-Cross Detection improves relay performance and extends product lifespan by reducing electrical stress during switching.
