Description

With LCM-40 KN presents mean well the first on the market of KNX-LED constant current driver for LED lighting systems in building automation, which can be set via DIP switch between 350 and 1050 mA can be preset. Via the integrated KNX interface can be used with these 40 Watt LED drivers, a complicated KNX-DALI gateway. The series works with 180 to 295 VAC AC voltage and offers different current strengths between 350 and 1050 mA. Thanks to the high degree of efficiency of up to 90%, the fan-less LED driver is a housing temperature between -30 to +90 °C under free air convection. In addition, he is with a Push-Dim-interface, operating hours counter and a feedback for power consumption. The Clo function (Constant Light Output) can also be used over a long operating time of a light despite aging of the LED chips for constant light intensity. LCM-40 KN also offers by master-slave interconnection the synchronisation of max. 10 operating devices. Allowing for a great flexibility for the design of LED lighting systems in the interior. The KNX-LED constant current driver LCM-40 KN of MEAN CORRUGATED are now available separately.

Hints

Caution!

Make sure you pick an LED driver/transformer that comes with the appropriate power rating.

Choose a driver/transformer that supplies approx. 30 pecent more watttage, as the current consumption (i.e. amperage) of the LEDs is key, and not the power rating of the LED provided by the LED manufacturer.

Keep in mind that the switch-on surge tend to be much higher.
