| NOTE | 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature. 2. Please refer to “DRIVING METHODS OF LED MODULE”. 3. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 4. Tolerance : includes set up tolerance, line regulation and load regulation. 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details. 6. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time. 7. The driver 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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf) 8. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains. 9. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less. 10. Please refer to the warranty statement on MEAN WELL’s website at http://www.meanwell.com 11. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft). 12.

DRIVING METHODS OF LED MODULE
- This series works in constant current mode to directly drive the LEDs.
DIMMING OPERATION
- 3 in 1 dimming function
- Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
- 1 ~ 10VDC, or 10V PWM signal or resistance.
- Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.
- Dimming source current from power supply: 100uA (typ.)
- Applying additive 1 ~ 10VDC
Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):
Applying additive resistance:
Note:
In the case of turning the lighting fixture down to 0% brightness, please refer to the configuration as follow, or please contact MEAN WELL for other options.
Using a switch and relay can turn ON/OFF the lighting fixture.

Frequently Asked Question
Q: What should I do if the LED driver overheats?
A: If the LED driver overheats, immediately disconnect power and allow it to cool down before investigating the cause. Ensure proper ventilation around the driver to prevent overheating in the future.
Q: Can I connect multiple LED drivers?
A: The maximum number of LED drivers that can be connected depends on the circuit breaker type and voltage. Refer to the manual for the specific details regarding the number of units that can be connected in a circuit.
