Input: 100 to 240 volts Output: 3 volts DC, 2-amp, 24 watts Size: 2.25″ x 1.5″ x 1.25″ Plug: 5.5mm x 2.1mm This 3-volt DC power supply is fully voltage-regulated and circuit-protected. It is a perfect choice for those using LEDs throughout their project. Although this power supply has an output of 3 volts, it works with all power connectors and other electrical components used for wiring at 12 volts. Know that LEDs require 3 volts and must be used with a limiting resistor or a voltage regulator to work with the 12 volts of most dollhouses. Most often used with the 701-0 mini power connector, but can be used with any 701 connector.
