Please note the dimmer may be substituted for any
Two-Way switches.
Do not connect more than the maximum number of transformers stated for each dimmer.
Dimmer Switches
FEATURES
Intelligent and LED Intelligent Dimmer Switches
incorporate the following advanced features
l
Suitable for dimming Low Voltage Halogen lamps via good quality,
fully dimmable electronic or wire-wound transformers. In addition,
LED Intelligent dimmer switches are suitable for dimmable LED bulbs
for incandescent replacement.
l
Can be used with good quality mains voltage halogen lamps
incorporating GU10 bases. Please check with lamp manufacturer to
determine suitability
l
Load current sensing:
These dimmers continuously monitor the load current to help protect
against overheating in wire wound transformers and to prevent
overloading of the dimmer for long term reliability
l
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 inherently have a very high inrush current at
switch on
Standard Dimmer Switches
l
Suitable only for use with fused GLS Tungsten Filament lamps to
BS EN 60064 and BS EN 60432-1
l
One way dimmer switches incorporate manual soft start
l
Incorporate thermal switches for protection against overload
