Frequently Asked Questions
Can the ELG-100-42AB dim LED strips using a standard 0–10V dimmer?
Yes. The ‘B’ function in the ELG-100-42AB supports 3-in-1 dimming: 1–10V analogue, PWM signal, and resistance dimming. This means it is compatible with most commercial 0–10V wall dimmers and lighting control panels used in architectural and retail LED installations.
What is the IP rating of the ELG-100-42AB and where can it be installed?
The ELG-100-42AB is rated IP65, providing full dust protection and resistance to water jets from any direction. It is suitable for covered outdoor locations, semi-exposed areas under canopies, and indoor damp areas such as car parks and food service facilities.
Can I use the ELG-100-42AB to power a dimmable 42V LED strip in a hospitality lighting project?
Yes. The combination of output adjustment (‘A’) and 3-in-1 dimming (‘B’) makes the ELG-100-42AB practical for hospitality environments where scene control is required. It delivers up to 95.76W at 42V and can be trimmed within the 21–42V CC range to match the fixture’s target operating voltage.
How much 42V LED strip can the ELG-100-42AB drive?
With a maximum output of 95.76W at 42V, the ELG-100-42AB can supply approximately 9.5 meters of strip rated at 10W per meter. Always check your strip’s rated power per meter and apply a derating margin; the actual length supported will vary based on strip wattage.
Can the ELG-100-42AB be used for museum or gallery accent lighting with dimming control?
Yes. The driver’s 3-in-1 dimming compatibility and output adjustability make it suitable for accent lighting in museums and galleries where precise light level control is required. Its 95.76W / 42V output supports medium-wattage 42V LED fixtures used in directional accent applications.
Does the ELG-100-42AB accept international mains voltages?
Yes. It accepts 100–305VAC, covering 120V, 230V, and 277V mains without manual switching. This makes it suitable for international projects or installations where supply voltage varies across circuits.
