    NOTE 1. All parameter NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
    2. Tolerance: includes set up tolerance, line regulation and load regulation.
    3. Derating may be needed under low input voltages. Please check the static characteristics for more details.
    4. Direct connecting to LEDs is suggested, but is not suitable for using addional drives.
    5. To fulfill requirements of the latesst ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
