Product Description Ordering Key S H 2 D 500W 1230
This 500W universal dimmer is designed for DIN-rail mounting. This universal dimmer is suitable for dim- ming resistive, inductive and capacitive loads and LED lamps (see LED lamps table). The maximum load of R, L, C type is 500W depending on the tempera- ture: the reduction is described according to the trend in the diagram “derat- ing curve”.
The dimmer automatically detects if the connected load is resistive, capacitive or inductive, but if a LED lamp is to be driven, the user has to select the right curve as described below. The dimmer is completely
programmable via the smart-house tool.
The technology used enables to electrically pro- tect the dimmer against short circuit, overload and over-temperature. Thanks to the internal bus, it can be easily connected to adjacent dimmers (see “wiring dia- gram”) without the need of cabling the Dupline® BUS. Futhermore, the integrated sink allows you to mount the dimmers adjacently without any reduction of the load due to the increased tem- perature.

Note: this is the maximum power supplied to the load: if an inductive transformer is used, the efficiency of about
60% has to be considered before connecting the lamps. If a capacitive transformer is used, the efficiency is about
