NSi Zero-Cross LED Rated TORK® Photocontrol


This photocontrol may look the same as others in the TORK® family but is totally redesigned on the inside:

  • Industry best 15-year warranty.
  • A robust relay tested by UL for electronic ballast and LED loads.
  • Zero-Cross switching extends the life of the relay contacts.
  • Heavy duty MOV provides greater surge protection over its life expectancy.
  • The only UL listed long life photocontrol with an electronic ballast/LED rating. 


The ZTL Series is designed to address the roadway lighting demands by matching expected fixture life and photocontrol life.
