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 75℃ 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-185H-C1050AB to drive high-voltage LED downlight arrays?

Yes. The HLG-185H-C1050AB delivers a constant 1050mA across a 95-190V output range, making it well suited for series strings of high-voltage LED downlights. At 199.5W, it can handle substantial arrays, and the built-in adjustment potentiometer lets you fine-tune output current to match the LEDs' optimal drive level.

Is the HLG-185H-C1050AB suitable for large LED signage modules that require constant current?

Yes. Its 1050mA constant-current output with a 95-190V compliance range can power long series strings of signage LED modules. The adjustable output and 1-10V/PWM dimming input allow brightness scheduling for day and night operation, which is common in commercial signage installations.

Can I dim the HLG-185H-C1050AB for architectural LED lighting projects?

Yes. The AB suffix indicates both an adjustment potentiometer and a 3-in-1 dimming interface that accepts 1-10VDC, 10V PWM or resistance between DIM+ and DIM-. This lets it work with lighting controls that provide one of these signals. At 199.5W and 1050mA, it can drive architectural LED fixtures wired in series where smooth dimming is required.

Can this driver power a series string of LED COB modules for high-bay lighting?

Yes, provided the total forward voltage of your COB string falls within the 95-190V compliance range and each module is rated for 1050mA drive current. The number of COBs you can connect in series depends on each module's individual forward voltage. The series' IP65 or IP67 rating also allows installation in damp industrial environments.

Can I install the HLG-185H-C1050AB in a sheltered outdoor location?

Yes. Its IP65 or IP67 rating protects against dust and water jets, making it suitable for covered outdoor areas, canopy-mounted fixtures, or ventilated enclosures. It is rated for a case temperature (Tcase) of -40°C to +90°C, with load derating at high temperatures per the derating curve.

How does the HLG-185H-C1050AB compare to other constant-current models in the HLG-185H-C series?

The HLG-185H constant-current family includes C500 (500mA, 200-400V), C700 (700mA, 143-286V), C1050 (1050mA, 95-190V), and C1400 (1400mA, 71-143V) variants, all rated around 200W. Lower-current models have higher compliance voltage for longer LED strings, while higher-current models suit LEDs that need more drive current in shorter strings. The AB suffix on each means it has both output adjustment and dimming input.
