Frequently Asked Questions
Can the ELG-75-42B be mounted in a wet outdoor location?
Yes. The ELG-75-42B is rated IP67, so it is protected against temporary water immersion as well as dust ingress. This makes it suitable for exposed outdoor sign cabinets, landscape fixtures, and building facade lighting where rain or splashing water can contact the driver.
How many meters of 42V LED strip can the ELG-75-42B power?
The ELG-75-42B delivers 75.6W at 42V and 1.8A. For a 10 W/m strip, the estimated maximum is about 7.5 meters; for a 12 W/m strip, about 6.3 meters. Divide 75.6W by your strip's rated power per meter and derate by 20% to stay within safe operating limits.
What dimming inputs does the ELG-75-42B support?
The 'B' suffix indicates 3-in-1 dimming: the driver accepts a 1–10V analog signal, a PWM signal, or a resistance input. This broad compatibility covers most common wall dimmers, lighting controllers, and building automation interfaces without additional converters.
Is the ELG-75-42B suitable for 42V LED strips in outdoor architectural lighting?
Yes. With 75.6W at 42V, IP67 waterproofing, and 3-in-1 dimming, the ELG-75-42B suits outdoor facade, bridge, or landscape accent lighting systems where remote dimming via an analog controller is required and weather protection is essential.
Can the ELG-75-42B power 42V LED modules in a parking structure or tunnel?
Yes. The wide -40°C to +85°C operating temperature range and IP67 protection make the ELG-75-42B suited to semi-outdoor environments like parking structures or tunnels, where temperature swings, vehicle exhaust, and moisture are common. Its 100–305VAC input also accepts industrial 277V feeds.
How does the ELG-75-42B compare to the ELG-75-42 base model?
The ELG-75-42 base model has no dimming interface, while the ELG-75-42B adds 3-in-1 dimming (10V, PWM, resistance). Both share the same 75.6W / 42V / 1.8A output, IP67 rating, and identical physical dimensions of 180 × 63 × 35.5 mm. Choose the 'B' when a dimming control input is required.
