Test conditions and notes11

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. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. 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.
5. 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)
6. 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.
7. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
8. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. 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).
11. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can I use the HLG-120H-C350AB with a dimmer to control long LED string brightness in architectural lighting?

Yes. The HLG-120H-C350AB delivers 350mA constant current over a 215-430V range and accepts 1-10V or PWM dimming signals. This makes it ideal for dimmable architectural lighting with long series strings of LEDs, such as cove lighting, facade outlines, or decorative contour lighting where smooth brightness control is required.

Is the HLG-120H-C350AB a good choice for dimmable LED backlit sign panels?

Yes. The high 215-430V CC range allows many LED modules to be connected in series for large sign panels, while the dimming input enables brightness reduction for nighttime operation or energy management. At 350mA and 150.5W, it provides reliable constant current across the full string with smooth dimming response.

Can the HLG-120H-C350AB drive a linear LED array for retail shelf lighting with dimming?

Yes, if the total forward voltage of your linear LED array falls within the 215-430V CC range. The 350mA constant current output maintains even illumination along the full length, and the dimming capability allows you to adjust brightness for different retail displays or time-of-day schedules.

How do I determine if the HLG-120H-C350AB is compatible with my LED string?

Sum the forward voltages of all LEDs in your series string and confirm the total falls between 215V and 430V. The LEDs must be rated for 350mA drive current. The number of LEDs depends on each LED's individual forward voltage. The adjustable potentiometer also lets you trim the output current between 175mA and 350mA to match your LEDs' rating.

Is the HLG-120H-C350AB safe to install in a dust-prone industrial environment?

Yes. The series' IP65/IP67 rating means the enclosure is dust-tight and protected against water jets. Combined with a case temperature (Tcase) range of -40°C to +90°C, it can withstand dusty, dirty conditions found in factories, workshops, and industrial production areas.

What are the differences between the HLG-120H-C350AB and the other C350 variants?

All HLG-120H-C350 variants deliver 150.5W at 350mA constant current with a 215-430V CC range. The C350AB (this model) includes both an adjustable potentiometer and a 3-in-1 dimming input (1-10V, PWM or resistance). The C350A has only the potentiometer for output adjustment. The C350B has only the dimming input with no manual adjustment.
