HLG-240H-48A 48V 240W LED Driver

The Mean Well HLG-240H-48A is a single-output switching power supply rated at 48 V and 5 A for 240 W maximum output. It accepts a wide AC input range from 90 to 305 V at 47 to 63 Hz. Output voltage and current are adjustable via internal potentiometers. The unit is built for LED lighting installations that require a constant-voltage source with user-set current limiting.

Ideal for lighting engineers and installers

This driver suits projects needing a 48 V constant-voltage supply with adjustable current up to 5 A, such as LED strips, modules or high-bay fixtures. The wide input range supports global mains voltages without manual switching. It is not intended for applications that require multiple isolated outputs, programmable dimming interfaces, or power levels above 240 W. Buyers needing parallel redundancy or DALI control should look at other product lines.

240 W headroom and current adjustment

At 48 V the unit delivers up to 5 A continuously, giving 240 W of usable power for LED arrays. The internal pots let installers trim voltage and current to match specific load requirements, providing margin against forward-voltage variation. Headroom ends at the 240 W limit; loads that exceed this will trigger protection or reduce output. No higher-power version or multi-channel variant is described in the data.

Questions about this item

What AC input range must my mains supply cover for this HLG-240H-48A to operate?

The driver accepts 90 to 305 VAC at 47 to 63 Hz, so any standard single-phase mains within that window will power it.

Can I keep my existing 48 V LED array and just swap in this 240 W driver?

Yes, provided the array draws no more than 5 A; the output is fixed at 48 VDC with a 5 A maximum, matching the same voltage rail.

How do I verify the driver is delivering the rated 240 W after installation?

Measure the output with a multimeter under full load — you should read 48 VDC and up to 5 A, confirming the 240 W capability.
