MonoRail Flush Transformer-60W LED. This single-feed flush transformer converts standard 120 line-voltage to 12 volts to provide the necessary voltage for powering a MonoRail low-voltage lighting system. It can power lamps totaling up to 60 watts. The transformer, concealed by a decorative canopy, fits in junction box and features a fast acting secondary circuit breaker that will safely turn the system off should a short occur. Once the short has been removed the unit can be reset by simply flipping the wall switch off and back on.
