900W Heavy-Duty Landscape Transformer | 120VAC | T-LT900 Corona Lighting • Electrical Marketplace

Deliver commercial-grade power and extended multi-tap distribution for large-scale outdoor projects with the T-LT900 Heavy-Duty Landscape Lighting Transformer. Encased in a heavy-duty stainless steel enclosure with a natural finish, this 900W triple-circuit transformer converts standard 120V AC household voltage down to multi-tap 12V through 22V AC output options across three independent circuits. This design ensures optimal voltage delivery across extreme distances and heavy multi-fixture home runs.

Built for contractor convenience and quick field mounting, the T-LT900 features a removable hinged door with a moisture-resistant gasket seal, template-free top and bottom mounting slots, and a removable bottom plate with pre-punched knockouts (3X½", 3X¾" conduit, and 1X1¾" cable feeder). It includes an oversized wiring terminal block to easily manage multiple low-voltage cable connections, internal space for plug-in mechanical or digital timers, and a 6-foot heavy-gauge, grounded, water-resistant power cord with a molded plug.

System protection is comprehensive: the primary circuit features automatic thermal shut-off protection, while each secondary circuit is guarded by high-performance magnetic circuit breakers that function as individual ON/OFF rocker switches. ETL listed to U.S. safety standards (UL1838) for landscape lighting fixtures and certified Pool & Spa ready, the T-LT900 is fully rated for submersible lighting installations and compatible with low-voltage magnetic dimmers.

Key Features:

Rugged Stainless Steel Enclosure: Premium stainless steel housing measuring 8-1/8" W x 16-5/8" H with a removable hinged door, moisture-resistant gasket seal, and a lifetime enclosure warranty.
900W Triple-Circuit Multi-Tap Output: Delivers 900W total capacity split across three independent circuits with 12V to 22V AC multi-tap options to eliminate voltage drop on long commercial runs.
Pool & Spa Rated Safety: ETL listed to UL1838 U.S. safety standards, certified Pool & Spa ready, and approved for submersible fixture connections.
Flexible Controls & Circuit Protection: Compatible with low-voltage magnetic dimmers, primary thermal shut-off, secondary magnetic circuit breaker switches per circuit, and factory or field-installed timer and photocell options.
Contractor-Friendly Wiring: Includes an oversized terminal block for multi-cable runs, removable bottom knockout plate, top/bottom template-free mounting slots, and a 6-foot grounded water-resistant power cord.
