Test conditions and notes11
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. Please refer to "DRIVING METHODS OF LED MODULE".
  3. 3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  4. 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. 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. 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. 7. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
  8. 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. 9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  10. 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. 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-C1400A to drive high-output COB LED downlights?

Yes. The HLG-120H-C1400A provides 1400mA constant current across a 54-108V range at 151.2W total, making it a strong match for high-lumen COB LED downlights that need a higher drive current. The adjustable output lets you trim the current to precisely match the LED module's rated forward current.

Is the HLG-120H-C1400A suitable for powering LED grow light arrays?

Yes, provided the grow light LED modules operate at 1400mA with a total forward voltage between 54V and 108V. At 151.2W, the driver can handle a meaningful grow light panel. Its wide 90-305VAC input works with most electrical systems, and its case temperature (Tcase) range of -40°C to +90°C, with derating per the output load vs temperature curve, accommodates warm greenhouse environments.

Can the HLG-120H-C1400A power series-connected LED modules for large-format signage?

Yes, as long as the total forward voltage of your LED module string falls within the 54-108V CC range. The 1400mA constant current output maintains even brightness across the series string. The adjustable potentiometer (700-1400mA) is useful for fine-tuning the output current to the modules' rated drive current.

What LED forward voltage range is compatible with the HLG-120H-C1400A?

The HLG-120H-C1400A operates in constant current mode at 1400mA with a CC voltage range of 54-108V. Your total LED string forward voltage must fall within this window for the driver to regulate current properly. The number of LEDs in series depends on each LED's individual forward voltage.

Can the HLG-120H-C1400A be used outdoors under a building soffit or awning?

Yes. The series' IP65/IP67 rating provides protection against dust and water jets, which is sufficient for covered outdoor locations like soffits, awnings, and canopies. Its case temperature (Tcase) range of -40°C to +90°C, with derating at higher temperatures, handles seasonal temperature extremes in most climates.

What are the differences between the HLG-120H-C1400A, C1400AB, and C1400B?

All three models output 151.2W at 1400mA constant current with a 54-108V CC range. The C1400A (this model) features adjustable output via a built-in potentiometer with no dimming input. The C1400AB adds both adjustment and 3-in-1 dimming (1-10V, PWM or resistance). The C1400B has the dimming input only and no potentiometer.
