300 Watt Pro Series Transformer

Add up the fixture wattage on each run and include 20–30% headroom for future growth and driver inrush. Choose the next size up if in doubt.

Multi‑tap units (e.g., 12/13/14/15 V) let you compensate for voltage drop so fixtures receive ~12 V at the end of long runs.

Magnetic (core‑and‑coil or toroidal) are robust and dimmer‑friendly; electronic are lighter but can be fussy with long runs—check fixture compatibility.

Keep runs short, use heavier wire, and use hub or T‑methods to balance. Target about 11.5–12.5 V at fixtures under load.

Mount above grade on a solid surface with drip loops. Keep it accessible, shaded if possible, and follow clearances in the manual.

Yes—use separate secondary taps, breakers, or multiple transformers for large sites. Some systems support 0–10 V or smart dimming per zone.

Look for secondary breakers/fuses, surge protection, thermal protection, stainless enclosures, and gasketed doors with lock hasps.

Most cabinets accept plug‑in photocells, mechanical timers, astronomical clocks, or Wi‑Fi modules. Follow wiring diagrams for add‑ons.

Use 12–10 AWG copper for long, higher‑load runs; 14–16 AWG for short/light circuits. Always follow the manufacturer’s ampacity charts.

Tighten lugs annually, inspect for corrosion or moisture, and re‑terminate any heat‑stressed conductors. Keep vents and weep holes clear.
