Mean Well HLG-240H-C1400A LED Driver

The Mean Well HLG-240H-C1400A is a constant-current LED switching power supply built for indoor and outdoor lighting installations. It delivers a fixed 1400 mA output with a maximum voltage of 179 V and a rated power of 250 W. The unit accepts a universal AC input up to 305 VAC and meets IP67 and IP65 ingress protection ratings for harsh environments.

Constant-Current Output Specification

The defining specification is the 1400 mA constant-current output, which determines compatibility with your LED array. The driver operates up to 179 V and 250 W, so the connected load must match this current and stay within the voltage and power limits. Selecting a driver with a different current rating will cause incorrect operation or damage to the LEDs.

Terminal Block and Protection Features

The C-Type variant provides a terminal block for input and output wiring instead of a cable, simplifying permanent installation in junction boxes or enclosures. Built-in protections cover short circuit, over current, over voltage and over temperature, while active PFC and up to 94 % efficiency reduce losses. The design meets 4 kV surge immunity per IEC 61000-4-5 and is rated for Class I, Division 2 hazardous locations.

Questions about this item

What does the 1400 mA constant-current rating mean when the unit is driving an LED string in a real installation?

The driver holds the output at 1400 mA while the voltage varies up to 179 V, delivering a maximum of 250 W to the LED load.

How does the IP67 / IP65 rating limit where the C-Type model can be mounted?

The C-Type version uses a terminal block for I/O and is not rated IP67 or IP65, so it must be installed inside a protected enclosure rather than directly outdoors.

What physical mounting provisions does the HLG-240H-C1400A have for fitting into a lighting fixture?

The unit is cooled by free air convection and has mounting holes on its chassis for screw fixing inside a luminaire or enclosure.
