Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
7. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
8. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
9. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
10. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-240H-C700AB to drive high-voltage LED string arrays for commercial signage?

Yes. The HLG-240H-C700AB delivers a constant 700mA across a CC voltage range of 178-357V, providing up to 249.9W. This makes it well suited for long series strings of LEDs used in large channel letters, billboard backlighting, or illuminated sign cabinets where high-voltage constant-current drive is required.

Is the HLG-240H-C700AB suitable for powering high-bay LED fixtures in a warehouse?

Yes. At 249.9W and 700mA constant current, this driver can power high-bay LED fixtures designed for high-voltage series LED configurations. Its IP65/IP67-rated series housing and -40°C to +90°C case temperature range (with derating at high ambient temperatures) make it suitable for warehouses, factories, and covered industrial environments.

Can I dim the HLG-240H-C700AB and also fine-tune its output?

Yes. The AB suffix means this model includes both an output adjustment potentiometer and a 3-in-1 dimming input (1-10VDC, 10V PWM signal, or resistance). You can use the potentiometer to trim the constant-current output level and the dimming input to control brightness dynamically from an external controller.

Can the HLG-240H-C700AB drive LED grow lights or horticultural lighting panels?

Yes, provided the LED panel is designed for 700mA constant-current drive within the 178-357V range. The built-in dimming input lets you adjust light intensity for different growth stages, and the working humidity rating of 20-95% RH (non-condensing) covers typical greenhouse conditions.

How many LEDs can I run in series with the HLG-240H-C700AB?

The number of LEDs depends on each LED's individual forward voltage. The HLG-240H-C700AB operates in constant-current mode at 700mA with a CC voltage range of 178-357V. Add up the forward voltages of your LEDs in series and ensure the total falls within that 178-357V window.

Can the HLG-240H-C700AB be mounted outdoors in a covered location?

Yes. The series is rated IP65 or IP67 depending on type, protecting against dust and water, which suits covered outdoor locations such as canopies, soffits, or ventilated enclosures. For heavily exposed installations, check the rating of your type and follow MEAN WELL's IP installation cautions in the user manual.

What is the difference between the HLG-240H-C700AB, C700A, and C700B models?

All three share the same 249.9W / 700mA / 178-357V CC core specs and 244.2 x 68 x 38.8mm case. The C700A has output adjustment only (potentiometer). The C700B has dimming input only (1-10VDC, 10V PWM or resistance). The C700AB combines both adjustment and dimming in one unit, giving you the most control flexibility.
