Product Description Ordering Key
S H 2 D 500W 230
This 500W universal dimmer is designed for DIN-rail mounting and is 2 DIN wide. This universal dimmer is suitable for dimming resis- tive, inductive and capaci- tive loads and LED lamps (see LED lamps table). The maximum connected load is
500W depending on the temperature: the reduction is described according to the trend in “derating 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 provided with memory for the last selected scenario.
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

Notes: if energy saving
lamps are used, attention has to be paid to the maximum inrush current at start-up: it must not be greater than
3.5A otherwise the overload protection will be activated.
