Appearance, Function and Applications

This dimmer is rotary controlled, meaning to turn the dimmer on, the knob needs to be turned clockwise, a click will be heard from the dimmer and the brightness will increase, respectively, by turning anti-clockwise the brightness will diminish and the click from the dimmer means the dimmer is off.
..................................................
V-Dim Thermal dimmers are suitable for 1 way circuits.
..................................................
The V-Dim Series Thermal Dimmers are Leading Edge and can be used with mains voltage lighting and good quality Low Voltage Electronic Transformers, mains incandescent GLS lamps (standard mains light bulbs), up to the maximum load as specified on the dimmer, GU10 or similar Hi Spot Mains Halogen lamps (only use good quality lamps) up to the maximum load as shown in the PDF instruction manual.
..................................................
The V-Dim Thermal Series are equipped with Self Re-setting Overload Protection, so is able to handle overload situations, for example, if the wattage of the bulbs/lamps are accidentally too high on a circuit. This is achieved by either, stepping down the dimmer's output to the lamps (if the watts are marginally overloaded), or the dimmer cuts out before there is any damage, (if the watts are grossly overloaded), until the load is reduced.
..................................................
When using Electronic Low Voltage Transformers we recommend that a maximum of 5 good quality dimmable Electronic Transformers are used (10 if Varilight Transformers) with this dimmer range. Please note: add the watts of the bulbs/lamps if using Varilight Transformers, to determine which wattage of dimmer to select, but if using another manufacturer of Transformer, add up the VA of the Transformers so it does not exceed the maximum of the dimmer. Please note that noise levels can depend on the quality of the Transformer being used.
..................................................

Limitations

The best suited dimmer series for dimming Electronic Low Voltage Transformers, including dimming more than 5 Transformers, is the V-Plus Series, which has many features including Overload Protection; Soft Start which is gentler on the load; and Dimmer Buzz Elimination, that can be created from the transformers.
..................................................
TVarilight Dimmers can NOT be used for wire-wound or torroidal Transformers. For Fan applications choose V-Dim Solid State Series, please check with manufacturer of appliance to be dimmed.
..................................................

..................................................
These dimmers will NOT dim LEDs, if dimming LEDs choose either the V-Pro, Multi-Point Remote, Multi-Point Touch, or V-Com Dimmer Series.
