NOTE

  1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25¢J of ambient temperature.
  2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  3. Tolerance: includes set up tolerance, line regulation & load regulation.
  4. Derating may be needed under low input voltages. Please check the static characteristics for details.
  5. Suitable for indoor use or outdoor use without direct sunlight exposure. Please avoid immerse in the water over 30 minutes.
  6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
  7. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC DIRECTIVE on the complete installation again.
  8. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  9. To fulfill requirements of the latest ERP regulation for lighting fixtures, this LED power supply can only be used behind switch without permanently connected to the mains.

NOTE:

1.If the dimming function is not used, all wire NC.

2. Io is actual output current and Ir is rated current without dimming control.

3. For the driver to operate properly, the load voltage must be maintained above the input voltage t, proximally 50% of the

  max. output voltage for any given model.

4. The dimming signal is allowed to be less than 1V, when it for 0-1V, the connected LEDs may flicker. Keeping dimming

  voltage greater than 1V in application is strongly recommended.

5. Do not connect the GND of dimming (gray) to the output. Otherwise, the LED driver can not work normally.
