4 Produt desription LED emergeny lighting ontrol gear Tridoni have used their extensive knowledge of LED modules and ontrol gear to develop the EM onverterled series of emergeny ontrol gear. With a range of unique operating features and ease of use EM onverterled sets new standards in LED emergeny lighting equipment.... Produkt desription EM onverterled en 4 33

5 Usage One emergeny unit for all LED light modules; ompatible with all LED ontrol gear EM onverterled is designed for use in emergeny luminaries in onjuntion with LED modules and LED ontrol gear from Tridoni and any other manufaturer. It is ompatible with LED modules for linear / area as well as downlight appliations and an be used with normal fixed output or dimming LED ontrol gear of up to 80 W power. The produt range is designed in a very small 30 x 21 x 179 mm housing, making it ideal for ompat LED luminaires where spae is at a premium. EM onverterled an be used with nikel admium (NiCd) or the smaller and more environmentally friendly nikel metalhydride (NiMH) batteries. Versions are available for 3 hours and 1 hour emergeny duration. The forward voltage range of 10 V to 200 V makes it ideal for use with most LED modules from Tridoni and other manufaturers....

6 Emergeny Operation Emergeny Operation When the mains supply fails, the EM onverter LED unit will swith the LED module from the normal LED ontrol gear supply to the emergeny ontrol gear supplied from batteries. This is done using 3-pole tehnology to ensure total isolation and ompatibility between the LED mains ontrol gear, emergeny ontrol gear and supply system and to ensure that the best possible EMC performane is ahieved. Immediately this swith over to emergeny operation ours the EM onverterled is deteting the total forward voltage of the LED modules onneted to adjusts the right LED urrent. The use of power ontrol tehnology ensures maximum lumen output in emergeny mode for the speified duration on any given module and battery pak.... Produkt desription EM onverterled en 6 33

7 Produt range Produt range The EM onverterled range offers 1.5 W to 5 W emergeny output power overed by a small range of produts. An EM onverterled with e.g. 3 W output power operates the onneted LED module with the rated output power of the EM onverterled. For this reason the ontrol gear is deteting the onneted LED forward voltage and adjusts the LED forward urrent to the orresponding value resulting in 3 W output power. I NOTICE At the lowest range of allowable forward voltage, the effiieny may be slightly lower. In this ase the output power is also slightly.

8 Legend P U I Emergeny output power: Given by the EM onverterled type LED forward voltage: Deteted by the EM onverterled LED forward urrent: Automatially adjusted by the EM onverterled Example: Given: LED forward voltage: (e.g.) 50 V LED forward urrent (at 50 V): 60 ma Wanted: Emergeny output power? Result: Emergeny output power: P = U * I = 50 V * 60 ma = 3 W By the use of power ontrol tehnology for the LED operation only two types of ontrol gear (EM onverterled 50V and EM onverterled 200V) are required to over all LED module types from 10 V to 200 V forward voltages. Different battery ell numbers offer flexibility in the available emergeny output power - 3 ells and 4 ells for SELV rated LED modules from 10 V to 50 V forward voltage and 4 ells or 5 ells for LED modules from 50 V to 200 V. The LED urrent in emergeny mode is automatially adjusted by the EM onverterled ontrol gear based on the total forward voltage of the LED modules onneted and the assoiated battery. The produt range offers 2 different types overing forward voltages between 10 V to 200 V. Control gear Forward voltage range SELV Number of battery ells EM onverterled 50V V SELV < 60 V 3 ells for lower light output in emergeny operation 4 ells for higher light output in emergeny operation EM onverterled 200V V Non-SELV 4 ells for lower light output in emergeny operation 5 ells for higher light output in emergeny operation Produkt desription EM onverterled en 8 33
