Overview

The NSI TORK ZTL124 is a zero-cross switching LED photocontrol light sensor designed for professional-grade dusk-to-dawn lighting control in residential and commercial exterior applications. Engineered by NSI Industries, this turn-lock photocontrol automatically activates exterior lights at dusk and deactivates them at dawn, providing energy-efficient operation for LED, CFL, induction, HPS, and HID lighting fixtures. The ZTL124 features zero-cross switching technology to handle high inrush currents from modern LED luminaires, enhanced 510 Joule MOV surge protection exceeding ANSI and NEMA requirements, and a silicone light sensor calibrated to human eye response for accurate light detection. Its conformal-coated, weather-resistant circuit board and UV-stabilized polycarbonate housing ensure reliable performance in extreme temperatures from -40°F to 158°F (-40°C to 70°C). The device operates on 105-305VAC at 50/60Hz, supporting 1800W Tungsten, 1100VA Ballast, and 8A or 2220W@277VAC LED loads. With a 15-year limited warranty and ANSI C136.10 compliance, the ZTL124 is ideal for streetlights, parking lot fixtures, floodlights, security lighting, and roadway applications. The turn-lock design features solid brass locking prongs for maximum corrosion resistance and electrical conductivity, while the delayed OFF response prevents false switching from transient light sources like passing vehicles. Choose from blue, green, or black dome colors to match utility standards or project requirements.
