Overview

The NSI Industries ZTL4801020J Zero Cross Fail On TurnLock Photocontrol is a high-performance, microprocessor-controlled device engineered for LED, CFL, induction, HPS, MH, and HID lighting systems requiring precise dusk-to-dawn control. Designed for 347-480V AC systems at 50/60Hz, this TurnLock-compatible unit delivers instant response with a 1.5:1 OFF/ON ratio and a 1.5 foot-candle turn-on threshold (±0.2 fc), ensuring accurate operation in roadway, parking, flood, and security lighting applications. Key features include 1020 Joule surge protection via MOV, exceeding ANSI and NEMA requirements, and a UL-listed industrial relay with positive snap-action switching for 15,000+ operations. The sealed IR-filtered silicon sensor provides human-eye response accuracy and resists drift, while the UV-stabilized polycarbonate housing and conformal-coated electronics ensure durability in extreme weather (-40°F to +140°F). Certified to UL773, CSA, and ANSI C136.10 standards, the ZTL4801020J supports tungsten (1000W), ballast (1800VA), and LED drivers (8A or 2220W @ 277VAC). Its fail-on mode ensures continuous operation during power anomalies, while the delayed OFF response prevents false triggering from transient light sources. Backed by a 15-year warranty, this NSI Industries SKU ZTL4801020J is ideal for municipal, commercial, and industrial lighting controls where reliability and longevity are critical.
