To ensure the power supply's lifespan, please do not use it at full load. We recommend that the power supply be used at 80% of its rated power. For example, if the power supply label is 400W, the power consumption should be: 400W * 80% = 320W. This power supply does not include voltage and current detection. It is not a constant voltage or constant current power supply and is only suitable for ordinary LED light strips. Warning: Not applicable to other devices such as motors, batteries, amplifiers, etc. Power settings Product name: LED driver/power supply/transformer Brand: Lincoiah Input voltage: AC 190V-240V (please note if local voltage is applicable.)
