Leading Edge Grid Mounted Slider Dimmer Units 250VA 400 VA and 630VA

Traditional leading edge technology dimmer units suitable for tungsten and halogen lighting systems.  Can be fitted to a variety of grid mounting systems using one of the included mounting adaptor plates.

Grid Slider
Adaptor Plates

This dimmer unit will control one or two way lighting circuits with nominal voltage supply of 220-240volts or will control the supply voltage to wire wound laminated transformers.  Suitable for use with tungsten lamps, mains or low voltage halogen lamps, some larger rated LED lamps but not suitable for use with florescent lamps or wire wound toroidal transformers. 

The casing body will require a 35mm deep grid mounting system back box but for a multiple installation with clusters of circuits,

a 47mm deep back box would be recommended to help with the installation.  Supplied complete with three adaptor plates and M2.5 fixing screws to enable fitment to MK Gridswitch or GridPlus Systems, Crabtree Grid Systems or DETA Grid Systems.

Please Note.  The 630VA rated unit will require two grid spaces adjacent to each other.


Push on-off control button at any sliding position of brightness.

Integral short circuit and overload fuse facility which will safely disconnect the dimmer unit.

Leading edge technology will function satisfactorily with a minimum circuit load of 60VA.

Will operate as part of a two way lighting circuit (duplicate on-off switch available separately).

Compatible with some electronic transformers and some larger rated LED lamps.

Conforms to BS EN 55015 : 2006 EMC and BS EN 60669-2-1 : 2004 standards.

Two year guarantee.
