Tronic Power Supply 150W, 12V AC Output for Pool Lighting

Our review

This Tronic unit is an AC voltage transformer rated at 150 watts, with a 12V AC output. Tronic presents it mainly for pool lighting, where a transformer steps mains voltage down to the lower AC supply such fixtures typically run on. It suits anyone replacing a failed transformer on an existing 12V AC lighting circuit, or building one where the total lamp load stays within the 150-watt rating. Before buying, add up the wattage of every fixture on the circuit, including any you plan to add, and leave headroom rather than running at the limit. Confirm your lights actually need AC rather than DC, since the two are not interchangeable. Also check the physical size and mounting arrangement against your old unit, and how it connects, because no dimensions or connection details are listed here. Comparable transformers differ in power rating, output type and housing, so match those to your setup first.
