Test conditions and notes10

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

FAQ

Can I use the HLG-320H-C3500B to drive high-power LED downlights in a commercial building?

Yes. The HLG-320H-C3500B delivers 3500mA constant current at up to 318.5W, making it capable of powering high-output LED downlight fixtures. The LED string's total forward voltage must fall within the 46-91V CC voltage range. Rated IP65 or IP67 depending on version, it suits damp or dusty mechanical rooms.

Is the HLG-320H-C3500B suitable for powering LED arrays in large illuminated signage?

It can work for signage modules that require high drive current at relatively low voltage. At 3500mA with a CC range of 46-91V, it is best suited for short series strings of high-current LEDs rather than long strings of low-current modules. Confirm that your sign modules' combined forward voltage stays within 46-91V.

Can I dim the HLG-320H-C3500B for nighttime brightness reduction in outdoor LED fixtures?

Yes. The B suffix indicates a built-in 3-in-1 dimming input (0-10VDC, 10V PWM, or resistance), allowing external dimming controllers or building automation systems to reduce output. This is useful for scheduling lower brightness at night in parking lot or pathway lighting applications.

How many LEDs can I run in series with the HLG-320H-C3500B?

The exact count depends on each LED's forward voltage. The driver operates in constant current mode at 3500mA with a CC voltage range of 46-91V, so you need to sum the forward voltages of your LEDs and verify the total stays within that range. Higher forward voltage LEDs will allow fewer in series; lower forward voltage LEDs will allow more.

Can I install the HLG-320H-C3500B in a semi-exposed outdoor location?

Yes. The HLG-320H-C series is IP65 or IP67 approved against dust and water, making it suitable for sheltered outdoor enclosures, soffits, or ventilated housings. For installations requiring submersion protection, confirm this version's IP rating first.

What is the difference between the HLG-320H-C3500B and the HLG-320H-C3500A?

Both share the same 318.5W, 3500mA, 46-91V constant current specs. The -C3500A includes a built-in potentiometer for output current adjustment (1750-3500mA) but no dimming signal input. The -C3500B provides a 3-in-1 dimming input (0-10VDC, 10V PWM, or resistance) instead. The -C3500AB combines both features, and the -C3500DA uses DALI dimming.
