HLG-240H-C2100 2100mA Constant Current LED Driver

ElecSuppliers Part Number GuideSep 06, 2026

HLG-240H-C2100 is a high-power constant current LED driver from the MEAN WELL HLG-240H-C series. It provides a rated output current of 2100mA and rated power of 249.9W, making it suitable for LED lighting systems that require stable current regulation and relatively high output voltage.

The model operates within a 59V to 119V constant current region and has a maximum open-circuit voltage of 122V. Its combination of high output power and constant current operation makes it suitable for demanding LED lighting designs where consistent LED current is important.

Electrical Characteristics of HLG-240H-C2100

The HLG-240H-C2100 delivers 2100mA nominal output current with a rated power of 249.9W. Within its specified constant current region, the driver maintains regulated current as the LED load voltage changes.

For applications requiring output adjustment, the A and AB versions of the HLG-240H-C series allow the current to be adjusted through an internal potentiometer. The adjustment range for the C2100 version is 1050mA to 2100mA.

The output current tolerance is ±5%, while current ripple is specified at a maximum of 5% at rated current. These characteristics are useful in LED systems where consistent light output and controlled electrical performance are required.

Wide Input Range for Lighting Systems

HLG-240H-C2100 supports an input voltage range of 90–305VAC and 127–431VDC, with an operating frequency range of 47–63Hz. This broad input range allows the driver to be incorporated into lighting equipment designed for different power distribution environments.

Typical efficiency for the C2100 model is approximately 93.5%. The power factor is also designed for high-power lighting applications, helping the complete lighting system maintain efficient AC input operation.

Built for High-Power LED Applications

With nearly 250W of rated output power, HLG-240H-C2100 is positioned for LED applications that require substantially more power than compact indoor lighting drivers.

The 59–119V constant current range is particularly relevant to LED modules and arrays using multiple LED strings or high-voltage LED configurations. Instead of regulating voltage as the primary output parameter, the driver maintains a controlled current level for the connected LED load.

This makes the HLG-240H-C2100 suitable for applications such as high-power outdoor luminaires, industrial lighting, architectural lighting and other LED systems requiring a 2100mA constant current source.

HLG-240H-C2100 Versions and Control Options

The HLG-240H-C series includes several output-current configurations, including 700mA, 1050mA, 1400mA, 1750mA and 2100mA versions. The C2100 model is the highest-current option in this series.

Different suffix versions provide different control and protection configurations. Depending on the selected version, designers can choose adjustable-current, dimmable or programmable lighting-control functions.

For systems requiring external dimming, the corresponding B and AB versions provide dimming functionality. The AB version combines dimming with adjustable output current, providing greater flexibility when the LED operating current needs to be configured during system development.

Protection and System Reliability

A high-power LED driver must handle changes in load conditions as well as abnormal operating situations. The HLG-240H-C series incorporates protection functions intended to help safeguard both the driver and connected LED equipment.

Its design is also suitable for demanding lighting environments where reliable long-term operation is important. The series uses a fanless construction, reducing the need for forced-air cooling and helping simplify lighting equipment design.

Choosing HLG-240H-C2100 for LED Projects

HLG-240H-C2100 is a strong option when an LED system requires approximately 250W of constant-current power with a nominal 2100mA output. Its 59–119V operating region provides designers with flexibility for high-voltage LED modules and arrays.

For applications that need current adjustment or dimming, the appropriate A, B or AB configuration can be selected according to the control requirements of the final lighting system.

With its high output power, wide input range and regulated 2100mA current, HLG-240H-C2100 can serve as a reliable power stage for professional LED lighting equipment and other high-power constant-current applications.
