Frequently Asked Questions
Can the ELG-240-C1050A be used to fine-tune the brightness of an LED high-bay fixture during commissioning?
Yes. The 'A' suffix indicates an output current adjustment feature, allowing the installer to trim the 1050mA output during commissioning without modifying the LED array. This is useful in high-bay and commercial lighting where precise lumen output must be calibrated on-site. The CC voltage range is 114–228V.
Is the ELG-240-C1050A appropriate for driving LED modules in covered outdoor or damp-location fixtures?
The ELG-240-C1050A is rated IP65, protecting against dust ingress and low-pressure water jets. It operates from -40°C to +85°C, making it suitable for covered outdoor luminaires, parking structure fixtures, and damp-location enclosures. For direct rain exposure without additional enclosure, the IP67-rated ELG-240-C1050 base model is a better fit.
Can the ELG-240-C1050A drive an LED array in a large-format retail or stadium lighting fixture?
At 239.4W and 1050mA constant current, the ELG-240-C1050A provides the power level needed for large LED arrays in retail, stadium, or sports lighting fixtures. The wide 100–305VAC input and adjustable output allow flexibility across different site electrical supplies and commissioning requirements.
What LED loads are compatible with the ELG-240-C1050A?
The ELG-240-C1050A drives LED loads in constant current mode at 1050mA, with a CC voltage range of 114–228V. The LED string must present a combined forward voltage within that range at 1050mA. The precise number of series LEDs depends on each LED's forward voltage at operating current.
How does the ELG-240-C1050A differ from the ELG-240-C1050AB?
The ELG-240-C1050A provides output current adjustment only, with no external dimming signal input. The ELG-240-C1050AB adds analog dimming (0–10V or PWM) on top of the adjustment capability. Both share the same 239.4W, 1050mA, 114–228V CC specs and IP65 rating.
Can this driver support LED systems in industrial facilities with high-ambient temperatures?
Yes. The ELG-240-C1050A operates up to +85°C ambient, which covers most industrial environments including foundries, furnace areas, and hot-process facilities. The metal case aids heat dissipation, and the 5-year warranty reflects design confidence in long-term high-temperature operation.
