CLS TF150AT Stainless Steel Toroidal Core Transformer Built-In Timer & Photocell (150W)

Small to mid size systems, such as a front yard, a pool deck or a single commercial bed, need a transformer that handles its own schedule all year. The CLS TF150AT is a 150 watt toroidal core transformer in a 304 stainless steel enclosure with an astronomic timer and a photocell built in.

How does the astronomic timer help through the seasons?

An astronomic timer follows sunrise and sunset through the year, so there is no resetting clocks as days get longer or shorter. Together with the photocell, CLS lists Dusk to Dawn, Fixed Timer and Manual Override modes, set from an LCD screen with Mode, Enter and arrow buttons.

Which voltage tap do I use for a long run?

The price guide lists 12, 13, 14 and 15 volt taps. Short runs near the transformer stay on 12 volts. Longer or heavier runs move to a higher tap so the farthest fixture still sees a usable voltage. Check each run before choosing the tap.

How much load can a 150 watt unit carry?

Total the VA of every lamp and fixture on the transformer and leave headroom rather than loading it to the full rating. The toroidal core with copper windings runs quietly, and the Gray Stainless Steel housing resists corrosion outdoors.
