MEAN-WELL PWM-120-12 Series Constant Voltage PWM Output LED Driver Owner's Manual

PWM-120 series is a 120W AC/DC LED driver featuring the constant voltage mode with P WM style output, which is able to maintain the color temperature and the brightness homogeneity when driving all kinds of LED strips. PWM-120 operates from 90—305VAC and offers models with different rated voltage ranging between 12V and 48V. Thanks to the high efficiency up to 90.5%, with the fanless design, the entire series is able to operate for -40 C +90 C case temperature under free air convection. The entire series is rated with IP67 ingress protection level and is suitable to work for dry, damp or wet locations. PWM-120 is equipped with dimming function that varies the duty cycle of the output, providing great flexibility for LED strips applications.

NOTE	1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature. 2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details. 3. Length of setup time is measured at first cold start. Turning ON/OFF the driver may lead to an increase of the setup time. 4. 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) 5. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃or less. 6. Please refer to the warranty statement on MEAN WELL’s website at http://www.meanwell.com 7.

Based on IEC 62386-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which can support for DALI power on function, otherwise the set up time will be higher than 0.5 second for DA type. ※ Product Liability Disclaimer：For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx

DIMMING OPERATION

Dimming principle for PWM style output
Dimming is achieved by varying the duty cycle of the output current.

3 in 1 dimming function (for Blank-Type)

Apply one of the three methodologies between DIM+ and DIM-: 0 ~ 10VDC, or 10V PWM signal or resistance.
Dimming source current from power supply: 100μA (typ.)

Applying additive 0 ~ 10VDC

Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):

Applying additive resistance:

Note :

Min. duty cycle of output current is about 0.15%, and the dimming input is about 6KΩ or 0.6VDC, or 10V PWM signal with 6% duty cycle.
The duty cycle of output current could drop down to 0% when dimming input is less than 6KΩ or less than 0.6VDC, or 10V PWM signal with duty cycle less than 6%.

DALI Interface (primary side; for DA/DA2-Type)

Apply DALI signal between DA+ and DA-.
DALI protocol comprises 16 groups and 64 addresses.
First step is fixed at 0.2% of output

Cautions

Before commencing any installation or maintenance work, please disconnect the power supply from the utility. Ensure that it cannot be re-connected inadvertently!
Keep proper ventilation around the unit and do not stack any objects on it. Also, a 10-15 cm clearance must be kept when the adjacent device is a heat source.

Mounting orientations other than standard orientation or operating under high ambient temperature may increase the internal component temperature and require a de-rating in output current.
The current rating of an approved primary /secondary cable should be greater than or equal to that of the unit. Please refer to its specification.
For LED drivers with waterproof connectors, verify that the linkage between the unit and the lighting fixture is tight so that water cannot intrude into the system.

For dimmable LED drivers, make sure that your dimming controller is capable of driving these units.PWM series requires 0.15mA each unit.
Tc max. is identified on the product label. Please make sure that the temperature of the Tc point will not exceed the limit.
DO NOT connect “DIM- to -V”.

Suitable for indoor use or outdoor use without direct sunlight exposure. Please avoid immersing in the water for over 30 minutes.
The power supply is considered a component that will be operated in combination with the 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.

FAQ

Q: What should I do if the LED driver does not power on?
A: Check the input power connection and verify that the voltage source is within the specified range.

Q: Can I connect multiple LEDs to one driver?
A: It is recommended to follow the manufacturer’s guidelines on the maximum number of LEDs that can be connected to a single driver to ensure proper functionality and longevity of the LEDs.
