Deliver maximum power and multi-tap distribution for high-demand commercial and large-scale residential landscape lighting layouts with the T-LT600 Heavy-Duty Landscape Lighting Transformer. Housed in a premium stainless steel enclosure with a natural finish, this 600W dual-circuit transformer converts standard 120V AC household voltage down to 12V, 13V, 14V, or 15V AC output taps across separate circuits, eliminating voltage drop across extensive and heavy-load wiring runs.
Engineered for contractor-friendly field installation, the T-LT600 features a removable hinged door with a moisture-resistant gasket seal, top and bottom template-free mounting slots, and a removable bottom plate with pre-punched knockouts (3X½", 3X¾" conduit, and 1X1¾" cable feeder) for versatile conduit and cable entry. It is equipped with an oversized wiring terminal block to manage multiple low-voltage cable home runs, internal support for plug-in mechanical or digital timers, and a 6-foot heavy-gauge, grounded, water-resistant power cord with a molded plug.
System protection and reliability are built-in: the primary circuit features an automatic thermal shut-off, while the secondary side is protected by high-performance magnetic circuit breakers that serve as integrated ON/OFF rocker switches. ETL listed to U.S. safety standards (UL1838) for landscape lighting fixtures and rated Pool & Spa ready, the T-LT600 is fully certified for use with submersible water lighting and compatible with low-voltage magnetic dimming systems.
