Frequently Asked Questions
Can the ELG-240-24B be mounted inside an outdoor below-grade landscape lighting vault?
Yes. The ELG-240-24B is rated IP67, providing full dust protection and resistance to temporary water immersion up to 1 meter. This makes it appropriate for below-grade landscape lighting enclosures where rain infiltration or pooling water may occur.
Is the ELG-240-24B a good fit for 24V LED strip lighting in a cold-storage facility?
Yes. The driver operates from -40°C to +90°C, covering the deep-freeze temperatures found in cold-storage and refrigerated warehouse environments. Its IP67 enclosure also protects against the condensation that forms when equipment moves between cold and ambient air zones.
Can the ELG-240-24B power 24V LED strips in a large outdoor parking structure or garage?
Yes. The IP67 waterproof rating handles moisture from vehicle exhaust, cleaning sprays, and rain ingress, while the -40°C to +90°C operating range covers the full seasonal temperature envelope of an unheated structure. At 240W, it supports the long continuous strip runs needed for multi-bay garage lighting.
How many meters of 24V LED strip can the ELG-240-24B support?
The ELG-240-24B outputs 240W at 24V. For a 14.4 W/m strip, 240 ÷ 14.4 gives approximately 16.6 meters; for a 10 W/m strip, up to 24 meters. Verify your strip's rated wattage per meter and apply a 20% derating margin for reliable long-term operation.
Does the ELG-240-24B support PWM dimming for use with smart lighting controllers?
Yes. The 'B' suffix designates 3-in-1 dimming, which accepts PWM, 0–10V analog, and resistance control signals. This covers the control interfaces used by most smart lighting systems, DMX-to-PWM converters, and DALI-to-PWM gateways.
How does the ELG-240-24B differ from the ELG-240-24AB?
Both models share the 240W, 24V, 10A rating and identical dimensions. The ELG-240-24B is rated IP67 waterproof and provides 3-in-1 dimming. The ELG-240-24AB is rated IP65 water-resistant and adds a built-in potentiometer for output voltage trimming on top of the same dimming capability.
