Hi John: The FTS4060 uses a power supply brick to convert the AC line to 30 VDC. That is in turn converted to a bunch of voltages by a switching mode power supply in the physics package sub assembly. Note that 30 VDC is a convenient value to make a charger for a "24 volt" lead acid gel cell type battery. There are some very simple charger circuits based on National Semi linear voltage regulators.
But be aware that having a lead acid battery in the same box that has a heater leads to acid fume etching of printed circuit boards. Guess how I know this. So it's best if the battery pack is outside the box with the electronics.
