Triac-dimmable constant voltage power supplies suit LED applications

Schukat has added Self Electronics' SLD75 triac-dimmable constant voltage power supplies to its range of power products, suitable for leading edge or trailing edge dimming. Self Electronics has developed these 75W triac-dimmable power supplies especially for LED applications in constant voltage operation without a separate control cable for dimming. Schukat has now introduced the SLD75-12VL-E and SLD75-24VL-E models to its range as a retrofit and upgrade solution in particular, e.g. for LED strips.

The LED power supplies from Self feature a SELV-compliant constant voltage output of 12V or 24V, and a dimming range from 5% to 100%. They are also protection class II compliant and offer open-circuit,short-circuit, overload and over-temperature protection, with automatic restart after the fault condition has been corrected. The MM marking means that the units can be mounted on materials with unknown flammability characteristics, while clamp connectors allow for fast installation.

With efficiency of 86.5% (at full load), these power supplies have an operational life of 30,000 hours at 45°C enclosure temperature. They can also be used as control gear independent of lamps. Self Electronics' SLD75-12VL-E and SLD75-24VL-E power supplies with a five-year guarantee are now available direct from stock at Schukat.
