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-C500AB for dimmable commercial LED ceiling fixtures?

Yes. The HLG-120H-C500AB delivers 500mA constant current at up to 150W with a CC voltage range of 150-300V. The AB suffix means it includes both output current adjustment and a 1-10V/PWM dimming input, giving you full control over brightness from a wall dimmer or building management system.

Is the HLG-120H-C500AB suitable for driving LED modules in illuminated signage with dimming?

Yes. At 500mA and up to 300V, it can power series-connected LED strings used in channel letters or lightbox signs. The dimming input lets you reduce sign brightness for nighttime operation or energy savings, and the adjustable output lets you fine-tune current to match the exact LED modules installed.

Can the HLG-120H-C500AB power high-voltage LED arrays in architectural lighting?

Yes. With 150W at 500mA constant current and a voltage range of 150-300V, it is appropriate for architectural accent lighting, cove lighting, or facade illumination using high-voltage LED modules. The series' IP65/IP67 rating allows installation in sheltered outdoor or damp indoor locations, and the dimming capability supports dynamic lighting scenes.

What dimming options does the HLG-120H-C500AB support?

The HLG-120H-C500AB has a 3-in-1 dimming input that accepts 1-10VDC, a 10V PWM signal (100Hz-3KHz) or a resistance between DIM+ and DIM-. This works with 1-10V dimming controllers, building automation systems, and 1-10V wall dimmers. It also includes a potentiometer for adjusting the baseline output current, so you can set both the maximum output level and the dimming range.

Can the HLG-120H-C500AB be installed in a damp or humid environment?

Yes. The series' IP65/IP67 rating means the enclosure is dust-tight and protected against water jets. This covers damp indoor locations like bathrooms, kitchens, or basements, as well as sheltered outdoor areas. Working humidity is rated 10-95% RH non-condensing, so avoid locations where condensation forms on the driver.

What is the difference between the HLG-120H-C500A, C500AB, and C500B?

All three models share the same 150W, 500mA, 150-300V constant current output. The C500A has output adjustment only (potentiometer). The C500AB has both output adjustment and a 3-in-1 dimming input (1-10V, PWM or resistance). The C500B has dimming input only, without output adjustment. Select based on whether you need adjustability, dimming, or both.
