Frequently Asked Questions
What dimming method does the ELG-75-C1400D2 support, and how is it different from the B variant?
The D2 suffix denotes a digital dual-signal (D2) dimming interface, which accepts both 0–10V analog and PWM control but does not include resistance dimming. The ELG-75-C1400B supports 3-in-1 dimming (0–10V, PWM, and resistance), while the D2 variant is designed for systems using 0–10V or PWM signals only.
Can the ELG-75-C1400D2 be used to power LED downlights in a building with a DALI-free 0–10V control infrastructure?
Yes. The ELG-75-C1400D2 accepts 0–10V dimming signals, making it compatible with 0–10V lighting control systems common in commercial buildings. It operates as a constant current driver at 1.4A output, suitable for LED downlight arrays whose combined forward voltage falls within its rated output range.
Is the ELG-75-C1400D2 appropriate for outdoor LED applications where the driver could get wet?
Yes. The ELG-75-C1400D2 is rated IP67, providing full protection against dust and temporary water submersion up to 1 meter. It is suitable for outdoor LED signage and architectural lighting installations where the driver is exposed to rain or splash.
Can this driver supply LED modules in a small constant-current array at 75W total load?
Yes. The ELG-75-C1400D2 delivers a constant 1.4A output at up to 75W, making it appropriate for small LED arrays where the total load does not exceed that capacity. The actual number of LEDs that fit in a series string depends on each LED's individual forward voltage.
What is the temperature rating of the ELG-75-C1400D2, and will it operate in high-temperature enclosures?
The ELG-75-C1400D2 is rated for operation from -40°C to +90°C. This wide range supports both cold-start outdoor installations and high-ambient enclosures such as sealed outdoor cabinets in warm climates, provided the case temperature does not exceed the rated maximum.
