An uninterruptible power supply (10) includes a backup power supply (50) mounted on a circuit board type base (30) and connected to a universal buss (40) which is also mounted on the base to be in parallel with a main power supply which is also connected to the universal buss. A plurality of voltage controllers (60) are also mounted on the circuit board and each connects the universal buss to an output terminal (64) whereby a plurality of different elements can be connected to the uninterruptible power supply and each element can have a voltage requirement which is different from the voltage requirements of the other elements. A signal control (96) is also included to visually, audibly and/or digitally indicate impending run-out of battery power.
