Specification Sheet

DESCRIPTION
This remote magnetic transformer converts standard 120 or 277 volt line-
voltage to 12 volts, providing the necessary voltage for powering a
MonoRail, Kable Lite, Wall MonoRail or FreeJack low-voltage lighting
system. This remote magnetic transformer can be used to power lamps
totaling up to 300 watts. This transformer is equipped with fast-acting
secondary circuit breaker that will safely turn off the system should a short
occur. Once the short has been removed the breaker can be reset.
INSTALLATION
This transformer must be installed in a remote but accessible location
(such as above the ceiling or in a closet). To simplify installation the
transformer should be located no more than 20' from the run or power
feed. The electrician will need to supply the proper gauge conductor from
the transformer to the power feed location based on distance (see Low-
Voltage Wire Size Table, below).
DIMMING
Dimmable with a 600 watt low-voltage magnetic dimmer. The dimmer is
placed on the line side of the transformer. (Consult dimmer manufacturer
for specifics). Dimming a transformer may create a buzzing sound, which
may be objectionable in some applications. A debuzzing dimming coil can
be purchased separately to reduce the audible noise.
OTHER INFORMATION
Input Wiring: Can be ordered to hard wire to a junction box or to plug in
with 16' power cord with plug. This transformer provides a single 300 watt
output and must be used with a single-feed canopy or other power feed
option (sold separately). 12 volt output transformers require the use of 12
volt lamps.
