Frequently Asked Questions
Can the ELG-240-C1750AB power LED downlights in a smart building with dimming controls?
Yes. The AB variant combines an adjustable output potentiometer with an analog/PWM dimming input, so it can be connected to a 0–10V or PWM dimming controller used in smart-building systems. At 239.75W and 1750mA, it can drive a string of high-power downlights with their combined forward voltage between 69V and 137V.
What do the 'A' and 'B' parts of the AB suffix mean?
The A indicates an adjustable output potentiometer for setting the nominal current level, while the B indicates a built-in analog or PWM dimming interface. Together they allow both a fixed current adjustment at commissioning and dynamic dimming during operation.
Is the ELG-240-C1750AB rated for outdoor LED signage use?
The IP65 rating on the ELG-240-C1750AB protects against dust and directed water jets, suitable for covered or semi-sheltered sign installations. For sign cabinets that may be directly exposed to heavy rain or require immersion protection, an IP67-rated variant such as the ELG-240-C1750B would be a better fit.
What LED string voltage range is compatible with this driver?
Running in constant current mode at 1750mA, the driver's output voltage adjusts between 69V and 137V automatically. The actual number of LEDs you can connect in series depends on each LED's individual forward voltage — the total string voltage must fall within 69–137V.
Can this driver be used in gallery or museum LED lighting where smooth dimming is important?
Yes. The built-in analog/PWM dimming input of the ELG-240-C1750AB allows smooth current reduction, which minimises visible flicker — a key requirement for gallery and museum display lighting. The 239.75W output capacity supports arrays of multiple LED spotlights or downlights in such installations.
Does the ELG-240-C1750AB operate across international supply voltages?
Yes. The driver accepts input from 100VAC to 305VAC, making it compatible with 120V, 230V, and 277V single-phase supplies. This allows the same driver model to be deployed in projects across different countries without needing a different SKU.
