Product Usage Instructions

To use the IDLV-25 series LED Driver, follow these instructions:

Ensure that the input voltage is within the specified range of 90 to 295VAC.
Connect the LED lighting system to the appropriate model of the IDLV-25 series LED Driver based on the desired output voltage.
Make sure the total load does not exceed the rated power of the LED Driver.
If dimming is required, refer to the PWM frequency and setup time specifications to adjust the output voltage accordingly.
If an auxiliary DC output is needed, connect the appropriate device to the designated terminals of the LED Driver. Note that the auxiliary DC output is only available for A-Type models.
Ensure proper grounding and electrical safety measures are in place.

OTHERS

All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25°C of ambient temperature.
De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
Length of set up time is measured at cold first start. Turning ON/OFF the driver may lead to increase of the set up time.
Aux. 12V will be damaged with short circuit; It will not be available with dimming off or output no load condition.
The driver is considered as a component that will be operated in combination with final equipment. Since MC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify MC Directive on the complete installation again.
The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).
To fulfill requirements of the latest Er regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.

DIMMING OPERATION

Dimming principle for PWM style output
- Dimming is achieved by varying the duty cycle of the output current. $MEAN-WELL-IDLV-25-Series-25W-IDLV-Series-Constant-Voltage-PWM-LED-Driver-fig- $3$$
2 in 1 dimming function
- Applying additive 0 ~ 10VDC $MEAN-WELL-IDLV-25-Series-25W-IDLV-Series-Constant-Voltage-PWM-LED-Driver-fig- $4$$
- Applying additive 10V PWM signal (frequency range 300~3KHz): $MEAN-WELL-IDLV-25-Series-25W-IDLV-Series-Constant-Voltage-PWM-LED-Driver-fig- $5$$

Note:

Min. duty cycle of output current is about 9% and the output current is not defined when 0%< Iout<9%.
The duty cycle of output current could drop down to 0% when dimming input is about 0Vdc, or 10V PWM signal with 0% duty cycle.
