HBG-240-36-AB circular LED driver
MEAN WELL HBG-240-36-AB is a circular AC/DC constant-voltage and constant-current LED driver for LED high-bay, low-bay, stage and spotlight luminaires. Its rated output is 36 V DC, 6.7 A and 240 W, with a 21.6–36 V constant-current operating region. Built-in output-current adjustment and 3-in-1 dimming. Match the LED load to the current, voltage window and power limit, and observe input and temperature derating. The catalog lists 36 V, 6.7 A and 240 W; observe the 240 W rating rather than increasing it to the arithmetic product.

Complete model
HBG-240-36-AB
Output architecture
Constant voltage (CV) plus constant current (CC). CV operation is usually used with an additional DC/DC LED driver; CC operation can directly drive the LEDs.
Rated output current
6.7 A
Rated output power
240 W. Observe this power limit together with the current and voltage limits.
Constant-current voltage window
21.6–36 V. The LED string configuration determines the operating voltage in this region.
Rated DC voltage
36 V
Version and function
Built-in output-current adjustment and 3-in-1 dimming; AB suffix; IP65.
Output-current adjustment
4.0–6.7 A via the built-in Io ADJ potentiometer.
Ripple and noise
250 mVp-p maximum; measured with 20 MHz bandwidth, a 12-inch twisted pair, and parallel 0.1 µF and 47 µF capacitors.
Voltage tolerance and regulation
Voltage tolerance ±2.0%, including setup, line and load regulation; line regulation ±0.5%; load regulation ±0.5%.
Analog dimming
Apply 1–10 V DC, a 10 V PWM signal at 100 Hz–3 kHz, or resistance between DIM+ and DIM−. The control changes the output constant-current level. Dimming source current: 100 µA typical.
Dimming transfer and off
The catalog graphs show 10–100% output current for 1–10 V DC, 10–100% duty of the 10 V PWM signal, or 10 kΩ/N–100 kΩ/N. N is the number of synchronized drivers. Use the illustrated external switch and relay arrangement for 0% brightness, or consult MEAN WELL for other off options.
Dimming connection limits
Do not connect DIM− to −V. Direct connection to LEDs is recommended for this dimming arrangement; do not use additional LED drivers with it.

Cooling and case temperature
Fanless free-air convection; operating case temperature −40°C to +75°C; maximum case temperature +75°C. These are case-temperature limits, not unconditional ambient full-load ratings.

Type HL source limitation
The catalog footnote discusses built-in use or potting the Io-adjustment hole for Type HL applications, but the HBG-240 safety row lists UL 8750 without a Type HL designation. Confirm the actual certification before specifying a Type HL installation.
System integration
This driver is a component used with final equipment. Re-qualify EMC on the complete installed system; the driver specifications do not replace final-luminaire compliance.
Catalog warranty statement
The manufacturer catalog states a 5-year warranty, subject to MEAN WELL’s warranty statement and conditions.
Installation requirements
Parameter
Model-specific information
Installation safety
Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself.
Ventilation and mounting
Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements.
System wiring and protection
Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system.
Environmental and load limits
Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person.
Connection seals and support
If waterproof connectors are fitted, secure their connections to prevent water entry. Verify the mounting structure and luminaire strength; use safety cables for bay-light applications.
Protective-earth installation
Connect the fitted FG/PE conductor or connector terminal to protective earth according to this exact model’s wiring diagram.
Weather protection
This IP65 model must be installed indoors or in a location sheltered from rain outdoors, as required by the installation manual. The IP rating does not permit immersion.
Dimming isolation
The LED installation manual identifies HBG analog dimming as not isolated from the secondary output. Follow this model’s DIM wiring and controller requirements.
