Frequently Asked Questions
Can the ELG-240-C1400A power LED downlights while allowing current adjustment on-site?
Yes. The 'A' suffix indicates an internal trimmer potentiometer that allows output current to be adjusted downward from the rated 1400mA. This is useful for fine-tuning light levels during commissioning without changing the control infrastructure.
Is the ELG-240-C1400A suitable for damp or splash-prone indoor locations such as car washes or food processing areas?
The ELG-240-C1400A carries an IP65 rating, which protects against sustained low-pressure water jets from any direction. This is sufficient for most damp indoor environments such as car wash equipment bays or food processing areas, though it is not rated for submersion.
Can I use this driver for LED arrays in tunnel or underpass lighting?
Yes. Its 239.4W output at constant 1400mA and IP65 protection level make it viable for tunnel and underpass LED fixture installations. The -40°C to +85°C operating range handles the temperature extremes typical of outdoor tunnel environments.
How many LEDs can I wire in series with the ELG-240-C1400A?
The driver's CC voltage range is 86–171V. The number of LEDs in series depends entirely on the forward voltage of each LED; the sum of all LED Vf values in the string must fall within 86–171V for the driver to regulate correctly.
What is the difference between the ELG-240-C1400A and the ELG-240-C1400AB?
The ELG-240-C1400A provides analogue current adjustment via a built-in trimmer potentiometer (output adjustable, no dimming signal input). The ELG-240-C1400AB combines that same adjustability with PWM/0–10V signal dimming, so both on-site trim and ongoing dimming control are possible.
Does this driver work with universal mains voltage, including both 120V and 277V systems?
Yes. The ELG-240-C1400A accepts input from 100 to 305VAC, covering 120V, 208V, 240V, 277V, and 305V mains supplies, making it suitable for North American, European, and industrial power systems without rewiring.
