Frequently Asked Questions
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 water-resistant rating and -40°C to +90°C operating range 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 dimming signal input (typically 1-10V, PWM, 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. Many multi-string horticultural LED boards operate in this voltage window. The built-in dimming input lets you adjust light intensity for different growth stages, and the IP65 rating handles greenhouse humidity.
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. Its IP65 water-resistant rating protects against dust and low-pressure water jets, making it suitable for covered outdoor locations such as canopies, soffits, or ventilated enclosures. For fully submerged or heavily exposed installations, a higher IP-rated enclosure would be advisable.
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 IP65 rating. The C700A has output adjustment only (potentiometer). The C700B has dimming input only (1-10V/PWM). The C700AB combines both adjustment and dimming in one unit, giving you the most control flexibility.
