Intermatic’s DT200LT 24-hour heavy-duty digital plug-in timer installs inside a Dauer stainless steel (SSP) or black powder-coated transformer, and turns the transformer on and off automatically based on easy 7-day programming. Featuring an automatic Daylight Savings Time adjustment, this UL-listed timer supports a maximum wattage of 1200 watts and auto-adjusts to sunrise and sunset time for dusk/dawn settings. A large, easy to read display makes programming and monitoring a breeze, while a battery backup makes sure your settings aren’t lost if the power goes out.
