Meanwell HLG Driver

Meanwell HLG-240H-24B & Meanwell HLG-120H-12B

- The Mean Well HLG-120H-12B is a rugged 120 W AC/DC LED driver that combines constant-voltage and constant-current modes for flexible LED system design. The “-12” model delivers a 12 V output and the “B” function adds the 3-in-1 dimming interface (1–10 V, 10 V PWM and resistance).

Key benefits

- Dual-mode (CV + CC) output for use with LED modules or LED arrays that require either constant voltage or a current-limited feed.

- Wide input range: operates reliably from 90 to 305 VAC, suitable for global AC mains.

- High efficiency (up to the series typical values), low losses and built-in active PFC for better system performance.

- IP67-rated sealed metal housing (robust for indoor and outdoor use) with Class I design.

- 3-in-1 dimming (model B): easy integration with common dimming controls.

- Comprehensive protections: over-voltage, over-current, short-circuit and over-temperature.

- Long lifetime (>62,000 hours) and industry-leading 7-year warranty.

Essential specifications (from datasheet)

- Output power: 120 W

- Nominal output: 12 V DC

- Rated current: 10 A

- Input voltage: 90–305 VAC

- Dimming: 3-in-1 (1–10 V / 10 V PWM / resistance) on “B” version

- Ingress protection: IP67 (sealed)

- Operating case temperature range: designed for wide temperature use

- Protections: OVP, OCP, SCP, OTP

- Typical lifetime: >62,000 hours

- Warranty: 7 years

Typical applications

- LED street and area lighting

- Parking lot and canopy lighting

- High-bay and industrial fixtures

- Greenhouse and horticulture lighting

- Any outdoor or damp-location LED installation requiring robust, dimmable power

Mean Well HLG-240H-24B — 240W CV+CC LED Driver

https://smppr-userpriv-cdn.simplified.com/usetldr/15819657/u/16185919/assets/9e1bbb3b-0912-4a01-a59b-a83e87d0f0a0/4.jpg?Expires=1775279218&KeyName=smppr-cloudstorage-signed-url-key&Signature=QDNi-d_9Wnf6ifBZFPOBx92BGRo=

Product overview

- The Mean Well HLG-240H-24B is a high-power 240 W AC/DC LED driver with the same dual-mode output concept. The “-24” model supplies a 24 V output and the “B” suffix indicates the integrated 3-in-1 dimming function for flexible lighting control.

Key benefits

- Higher wattage for larger LED banks or multi-channel fixtures while keeping the same robust HLG platform benefits.

- Wide universal input (90–305 VAC) with active PFC for cleaner power and better system performance.

- Fanless, sealed metal housing rated for outdoor use (IP67), minimizing maintenance and improving reliability in harsh environments.

- 3-in-1 dimming (1–10 V, 10 V PWM, resistance) on the “B” variant for smooth compatibility with control systems.

- Full protection suite and long expected service life backed by a 7-year warranty.
