They may also have disturbing influence on nearby electrical appliances.) • power of the transformer must be higher than the input power of the lights, recommended reserve is 20%, for continuous lighting the reserve should be increased to 30% • the transformer should have a minimum distance of 0.5 m from other electrical appliances • place in such a way that sufficient ventilation – heat dissipation – is provided • cable length 2 m • CE certificate • circular connector at output • in order to achieve optimal function, it is recommended to have the transformer as close to the light source as possible (Longer cables cause voltage losses and a subsequent drop in luminous intensity. They may also have disturbing influence on nearby electrical appliances.) • power of the transformer must be higher than the input power of the lights, recommended reserve: 20%, for continuous lighting the reserve should be increased to 30% • the transformer should have a minimum distance of 0.5 m from other electrical appliances • place in such a way that sufficient ventilation – heat dissipation – is provided • cable length 2 m • CE certificate • covered terminal box for possible connection of other cables (must be carried out by an author- ised person) Warning It is not possible to combine 12 V LED strips with the 24 V transformer and vice versa. The transformer must always have sufficient reserve for the respective LED strip set. During normal use, the reserve should be 20%, if used for more than 5 hours, we recommend increasing the reserve to 30% or more. Offered transformers have protection to prevent damage, the transformer switches off at overloading and after reducing the load and cooling, the transformer is functional again. However, overloading has a negative impact on the overall service life. The transformer should be installed so that it can be accessed and possibly replaced at any time and it should be well ventilated. Installation in small, unventilated space reduces its service life. Please note that the supply voltage must comply with ČSN EN 60038, damage due to over-voltage in the electrical network is not a reason for placing a complaint. Complaints are solved by replacing the faulty transformer. Other costs related to replacing the connection are not recognised. Transformer power (W) = x + 20% (30%) x = LED strip length (m) × LED strip input power (W/m) Example: when using a strip with 14.4W/m and length of 2.5 m, the power of the strip is 36W + 20% reserve (7.2 W) = 43.2 W. You will thus need a trans- former with more than 44 W 24 V transformers with a 5-year warranty can be found in Strong LED strips series, p. 10.9. YEARS WARRANTY CONTENTS
