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, at overloading the transformer switches off 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 with replacing the connection are not recognised. Transformer power (W) = x + 20 % (30 %) x = LED strip length (m) × LED strip power input (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 transformer with more than 44 W. CONTENTS
