UL listed ac to dc 24v led power supply 120w for led strip
In order to obtain the best performance and the longest operational life from led strip power supply, it is recommended that you do not exceed 90% of the unit’s output amperage. To determine if this led power supply suits your desired application, add together the total wattage of the equipment you intend to use with this unit and divide this total by 24 volts to find the total amperage draw that will be placed upon the converter.
