• Finding Transformer Load: Low voltage systems require the use
of a transformer to reduce standard 120-VOLT power from your
home to 12-15 VOLTS. To determine the transformer size you will
need, add up the wattages of all lamps you plan to use. Select a
transformer that matches as closely as possible to the total
lamp wattage. 例如, if you have 11 fixtures all rated at
24.4 watts, you will need a 300 watt (VA) transformer (11 x 24.4 =
268.4 watts). 一般来说, the total lamp load should not be less
than one-third the transformers wattage rating, nor exceed its
maximum wattage capacity. If your total wattage is too high,
either divide the load between two transformers, or use a more
powerful transformer
