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. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
8. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
9. 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).
10. 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
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-320H-C1400B to drive high-power LED downlights in a commercial building?

Yes. The HLG-320H-C1400B delivers a constant 1400mA across a voltage range of 114-229V, providing up to 320.6W of power. This is well suited for driving series strings of high-power LED downlights in commercial ceilings. Rated IP65 or IP67 depending on version, it also suits damp locations such as covered parking garages or canopied walkways.

Is the HLG-320H-C1400B suitable for powering high-bay LED fixtures in a warehouse?

Yes. At 320.6W and 1400mA constant current, the HLG-320H-C1400B can drive high-bay LED modules that operate within its 114-229V output range. The built-in dimming input (0-10VDC, 10V PWM, or resistance) lets you reduce light levels during low-activity periods to save energy. Its -40°C to +85°C case temperature (Tcase) range handles the temperature swings typical of unconditioned warehouses.

Can I use the HLG-320H-C1400B for large LED signage modules?

Yes, provided your signage LEDs operate at 1400mA and the total string voltage falls within the 114-229V range. The 320.6W capacity supports demanding sign installations, and the dimming function allows you to lower brightness at night. The IP65/IP67-approved enclosure protects the driver in sheltered outdoor sign enclosures.

How many LEDs can the HLG-320H-C1400B drive in series?

The number of LEDs depends on each LED's forward voltage at 1400mA. The driver's constant-current output range is 114-229V, so you divide that range by the individual LED forward voltage to determine the minimum and maximum number of LEDs in your series string. Always verify that your total string voltage falls within 114-229V under operating conditions.

Can the HLG-320H-C1400B be installed in an outdoor location exposed to rain?

The HLG-320H-C series is IP65 or IP67 approved, protecting against dust and water, but the sheet does not state which rating applies to the C1400B. It is suitable for sheltered outdoor locations such as under eaves, canopies, or inside ventilated enclosures. For fully exposed installations or any risk of submersion, confirm this version's rating first.

What are the differences between the HLG-320H-C1400A, C1400AB, C1400B, and C1400DA variants?

All four share the same 320.6W / 1400mA core specs with a CC output range of 114-229V. The -C1400A adds output current adjustment via built-in potentiometer (700-1400mA). The -C1400AB combines adjustment with 3-in-1 dimming (0-10VDC, 10V PWM, or resistance). The -C1400B provides dimming input only. The -C1400DA replaces analog dimming with a DALI interface (IEC62386-101, 102). The series is IP65 or IP67 approved depending on version.
