This transformer is designed to power the Aquatec 8800 series booster pumps. The transformer is both current and temperature protected for additional safety.  This transformer plugs into standard 2 prong outlets and powers the Aquatec CDP 8800 booster pump. You can purchase the transformer by itself which allows you to get just the part you need, so that way you're replacing a single piece, instead of the pump itself.  It's great for custom setups or replacements.
