Description
MK dimmer switches can fall into one of four categories
1)
Standard Dimmer Switches
2)
Intelligent Dimmer Switches
3)
Non-UK Dimmer Switches
4)
LED Intelligent Dimmer Switches
Standard Dimmer Switches
Dimmer Switches belonging to this category employ simpler electronic circuitry and
the CE marked products make use of thermal switches to conform to the very stringent
requirements of the Standard BS EN 60669-2-1, for overload protection. They are only
suitable for use with normal tungsten filament lamps, conforming to BS EN 60064:1996
and BS EN 60432-1 Standards and do not have any added features, e.g. soft start,
ability to control dimmable transformers for low voltage, etc.
Standard Dimmer Switches are not suitable for use with transformers for Low Voltage
Lighting or Fluorescent Loads, including Energy Saving Lamps.
Intelligent and LED Intelligent Dimmer Switches
Dimmer Switches belonging to this category, employ the latest, state of the art,
micro-controller based electronic circuitry and use current sensing to compute the
load conditions. These products show progressive reaction to overload conditions,
depending on the extent of overload as shown in the table below. List numbers
belonging to this category are identified by the suffix letters LV, e.g. K1501 WHI LV.
All MK Intelligent Dimmer Switches employ one pole change over switches to
facilitate two way switching.
MK Intelligent and LED Intelligent Dimmer Switches are not suitable for use with
Fluorescent Loads, including Energy Saving Lamps.
*Non-UK Dimmer Switches
Dimmer switches belonging to this category only conform to the relevant parts of
BS EN 66069-2-1. Loads suitable for use with standard dimmer switches above are
also suitable for use with this category of dimmer switch.
Only one Dimmer Switch can be used in a two-way switching circuit.
