Safetran Model 010520 Transformer

              

This unit is a transformer, that converts 120 Volts AC to a low voltage AC that the light bulbs can use. 
It has a 115/230VAC input, and as shown in the photo, it is connected to run off 120V.
The transformer is rated at 0.31KVA, or 310 watts into a non-reactive load.

The output is 0.5V to 15.5VAC in 1/2 volt steps.
The numbered terminals correspond to the voltage output, starting at "8", and going thru "15",
The terminal labeled "5" is for the half volt tap.
The output wires are connected to "5" and "13", giving us 13.5V,

The base is 6 x 6 1/2, exclusive of the mounting flanges, and 7 1/2" high - it weighs only about 8 lbs.
