    Some ideas for a 24VAC dimmer?

    All dimmer is designed to use on main power {eg 220VAC} and is imposible to control a 24VAC load. I found on net manny DC dimmers for low power but no for AC. I need a schematic for a simple 24VAC dimmer. I mention that i intend to use this for a 24VAC 48W 2Aheater element. Please help.
