features
Suitable for dimming Low Voltage
Halogen lamps via good quality, fully
dimmable electronic or wire-wound
transformers.
Unidirectional current sensing.
While being used with wire-wound
transformers for low voltage lighting,
these dimmer switches continuously
monitor the drive conditions to the
transformers, which require essentially,
bi-directional a.c. supply at their input
terminals. If, due to some fault

condition, the supply to the wire-
wound transformer is detected to be
unidirectional, which could result in
over-heating and/or damaging the
transformer, the dimmer switches’
circuitry automatically stops supplying
the transformer after a few cycles of
detected unidirectional supply.
Soft Start, which gradually increases
the light output from the load over 1
to 3 seconds after switch on. The Soft
Start feature is also particularly
beneficial when used to dim Mains
Voltage Tungsten Halogen lamps which
have inherent very high inrush current
at switch on.
