Frequently Asked Questions
Can the ELG-240-C1750B be used with a 0–10V dimmer for LED downlight control?
Yes. The B suffix indicates a built-in analog dimming interface, compatible with 0–10V or PWM dimming signals. This allows the driver to be integrated into standard commercial dimming systems controlling LED downlight circuits, with the output current reduced proportionally as the control signal decreases.
Is the ELG-240-C1750B suitable for fully outdoor LED installations exposed to rain?
Yes. The IP67 rating means the enclosure is sealed against dust and can withstand temporary immersion in water, making it appropriate for outdoor LED sign cabinets, facade-lighting enclosures, or bollard luminaires exposed to direct rainfall.
What is the output voltage range this driver can support?
The ELG-240-C1750B is a constant current driver; its output voltage self-regulates between 69V and 137V to maintain a steady 1750mA. The actual string voltage within that window depends on the total forward voltage of the LED load connected.
Can I use this driver to power large LED arrays in architectural or landscape lighting?
Yes. At 239.75W and 1750mA with an IP67 enclosure and a -40°C to +85°C operating range, the ELG-240-C1750B is well suited for high-power LED arrays in exposed architectural facades, landscape ground fixtures, or pathway lighting that requires weatherproof, dimmable constant-current drive.
How does the ELG-240-C1750B differ from the ELG-240-C1750A?
The A variant offers an adjustable output potentiometer for trimming the nominal current but no dimming interface. The B variant provides an analog/PWM dimming input for dynamic control but does not include the adjustable potentiometer. The B also carries an IP67 rating compared to the IP65 of the A variant.
Does the ELG-240-C1750B work on 277V commercial circuits?
Yes. The driver accepts any AC input from 100V to 305V, which includes the 277V single-phase circuits common in North American commercial buildings, as well as 120V, 208V, and 240V supplies.
