The doorbell transformer must support 220-240V AC on the input side and anywhere from 8 to 24V AC on the output side. Often the low voltage side will use screws as connection points instead of wires (as shown in picture). If more than two output connection points or wires are available, the transformer offers more than one output voltage.
A ground wire is not required, but will not impede functionality if one exists.
Doorbell transformers may offer different wattage (VA) ratings. Given our extremely low power consumption requirements of the adjustable power supplies and meters, even the lowest wattage transformer will be adequate in our setup.
*Included in our control panel kits (240V only, for international use) as DIN rail mount power supplies. Eliminates the need for separate doorbell transformers and adjustable DC power supplies used in the original design.
