Frequently Asked Questions
Can the ELG-100-C500AB be used in a dimmable LED downlight installation with a 1–10V control system?
Yes. The AB suffix means this driver supports both output current adjustment and three-in-one dimming (1–10V, PWM, and resistance). This makes it directly compatible with standard 1–10V architectural dimming infrastructure used in commercial and hospitality downlight systems.
Is the ELG-100-C500AB suitable for LED signage modules that require field-adjustable current levels?
Yes. The built-in potentiometer allows the output current to be trimmed to match the LED module's optimal drive level, while the dimming inputs enable dynamic brightness control after installation. The IP65 rating and wide input range of 100–305VAC make it appropriate for a variety of signage enclosure environments.
What is the difference between the ELG-100-C500AB and the ELG-100-C500A?
Both models offer output current adjustment via a trimmer potentiometer. The ELG-100-C500AB adds dimming capability (1–10V, PWM, resistance) that the ELG-100-C500A does not have. Both are rated IP65 and share the same 100W, 500mA, 100–200V CC specifications.
How many LEDs can I connect in series to the ELG-100-C500AB?
The CC voltage range is 100–200V. Connect LEDs in series such that the total string forward voltage falls within that range. The number of LEDs depends on each LED's forward voltage — do not assume a fixed count without checking your specific LED's datasheet.
Can the ELG-100-C500AB be installed in a partially exposed outdoor location?
The driver's IP65 rating protects against dust and water jets, making it suitable for sheltered outdoor or semi-outdoor locations such as covered walkways, outdoor corridors, and canopy fixtures. For fully exposed or submersion-risk environments, the IP67-rated ELG-100-C500B would be the more appropriate choice.
