When a pool is equipped with multiple lights, more power is required. House of DURATECH offers you the separate toroidal transformers. These “donut” shaped transformers are smaller, lighter, more energy efficient and safer than conventional stacked laminated transformers. They offer two versions, each in three different sizes. The Toro-DIN can be mounted on a DIN-rail while the IP64 encapsulated wall mount model is splash proof.
