LED driver Friwo LT40-36/1050 can be mounted even under an eaves

In fact, majority of features of a new a new LED driver (power supply) - LT40-36/1050 WP (1894661) were mentioned in a subject and a preface of this article. But not to be that brief, we can add, that the new LED driver features the same good properties like its familiar descried in the article - Friwo drivers not only drive your LEDs but even control them .... From the basic types it differs mainly by a water-tight design - by encapsulation in a resin, that´s why it also withstands operation in a humid or dusty environment. This version doesn´t have an external input, thus it operates only as “standalone”, in a “constant current, limited voltage” mode. Output voltage 15-36V means, that the LED driver should only supply such a module, whose forward voltage (Vf)at a given current is 15-36V, what in praxis means approx. 6-11 (12) white LEDs in series.

That´s why LT40-36/1050 operates as a power supply, whose open voltage (without a load) is 36V. This voltage remains constant up to 1000 mA current drawing and then the voltage drops down to 15V when a current reaches 1050 mA. This ensures a constant current, i.e. if we for example connect a LED module with Vf=24V, the driver will source 1050 mA current (at 24V). LT40-36/1050WP shouldn´t be used to supply modules with a Vf lower than 15V. In such case, the types handling lower voltages are suitable, for example LT10-16/700 or LT20-28/700. If we wish to reach a maximum power from a given LED driver, it´s naturally beneficial to use a LED module with a Vf on an upper level of an output voltage of a given LED driver (33-36V in this case).
