Total Light® 300 Watt Stainless Steel Low Voltage Transformer

Product Overview

The Total Light TL-TRAN300-SS is a 300-watt low-voltage landscape lighting transformer designed to supply stable power to compatible 12-volt outdoor lighting systems. Its 12V–15V multi-tap output gives installers flexibility when planning medium-to-large landscape lighting layouts and addressing voltage drop across properly sized cable runs. The additional capacity makes this transformer suitable for projects that combine path lights, accent lights, wall-wash fixtures, deck lights, hardscape lights, and other compatible low-voltage components within one carefully calculated system.

The transformer is housed in a heavy-duty stainless steel cabinet suitable for indoor or outdoor installation. A sealed, lockable access door helps protect the internal wiring area and discourages unwanted adjustments. The large internal compartment and terminal strip provide working room for organizing multiple cable runs. Pre-scored knockouts, a quick-mount bracket, and a removable bottom panel support a more efficient installation, while the attached 6-foot power cord helps simplify placement near an appropriate power receptacle.

Built-in system protection includes surge suppression, primary thermal protection, and a secondary-side magnetic circuit breaker. The transformer also includes a receptacle prepared for a compatible plug-in timing control, allowing the landscape lighting schedule to be automated when a timer is added. Before installation, calculate the combined fixture and lamp wattage, allow reasonable unused capacity, and account for cable gauge, cable length, and voltage drop. Review the linked specification sheet before mounting or connecting the transformer.

System Compatibility

Use the TL-TRAN300-SS with compatible low-voltage landscape lighting fixtures, lamps, cable, connectors, and controls. The combined connected load must remain within the transformer’s 300-watt capacity. Voltage-tap selection should be based on cable gauge, cable-run length, connected wattage, and measured voltage at the fixtures.

Installation and Planning Notes

• Calculate the combined wattage of every fixture and lamp before installation.
• Allow reasonable unused capacity rather than loading the transformer to its maximum rating.
• Use outdoor-rated low-voltage cable and approved connectors appropriate for the project.
• Select the correct output tap after accounting for cable length, load, and voltage drop.
• Mount the cabinet in an accessible location near a suitable power receptacle.
• Keep the lockable door and removable bottom panel accessible for installation and service.
• Follow the specification sheet and applicable electrical requirements.

Frequently Asked Questions

How many lights can the TL-TRAN300-SS operate?

The number depends on the wattage of each lamp or integrated fixture. Add the wattage of the complete lighting layout, keep the load within the 300-watt rating, and allow reasonable unused capacity.

Why does the transformer have 12V–15V output taps?

The additional taps help installers address voltage drop caused by cable length and connected load. Select the tap using system calculations and voltage measurements at the fixtures.

Is a timer included?

No. The transformer includes a receptacle prepared for a compatible plug-in timing control, but the timer or other control is sold separately.

Can the transformer be installed outdoors?

Yes. The stainless steel cabinet is intended for indoor or outdoor installation. Follow the specification sheet and applicable electrical requirements when choosing the mounting location.
