Lutron® Rania® RNSU-452B-F single electronic dimmer. Universal compatability and 450 W VA max load.

The Rania® RNSU-452 dimmer is classed as a universal dimmer meaning it will handle most types of lighting without additional interfaces.

Incandescent, magnetic and electronic low voltage systems are all catered for by the dimmer up to 450 W / VA. (full spec. below). It has leading and trailing edge capability, is fully CE approved and features auto resetting thermal overload, over current and short circuit protection.

The control plate has up and down buttons plus a single button for full on or fade off. Simply double tap for fade to full on and tap for a gentle fade to off, (Fade times can be adjusted) plus you can set a level for the lights to turn to when switched from off. A discrete set of led's on the control plate show the current lighting level.

Unlike transformer based dimmers these do not buzz, they use triac's which electronically clip the electrical wave form causing the lights to dim.
(In fact they switch on an off hundreds of times a second, far quicker than we can perceive. This has NO detrimental effect on bulbs and even cuts your power bills as the lights are not on constantly).

Requiring just a 2 wire installation they are simple to fit, easily replacing existing switches. All that is required is at least 32mm of depth.

To control the light from more than one place simply add RDSU or RDDU accessory dimmers. Existing 2-way switches can be used with the RNSU for remote switch on/off only.
(Maximum of 9 accessory dimmers can be fitted to one main dimmer. Maximum wire length from dimmer to accessory: 50m)

Various finishes are available to order, 2 are shown here. White and satin nickel
