Frequently Asked Questions
Can I use the ELG-240-C1050B to drive LED downlights in a commercial lighting installation?
Yes. The ELG-240-C1050B outputs a constant 1050mA across a CC voltage range of 114–228V, making it well-suited for series strings of high-power LED downlights whose combined forward voltages fall within that range. At 239.4W total output power, it can support a substantial array of luminaires from a single driver.
Is the ELG-240-C1050B suitable for outdoor or wet-location signage?
Yes. It carries an IP67 rating, meaning it is protected against temporary immersion in water, so it can be used in outdoor signage cabinets, facade installations, and other damp or wet environments without additional waterproof enclosures.
Can this driver power LED modules inside an outdoor sign exposed to rain?
The IP67 enclosure rating means the ELG-240-C1050B withstands water immersion up to 1 metre for 30 minutes, making it suitable for sign modules in direct rain exposure. Its operating temperature range of -40°C to +85°C also accommodates extreme outdoor climates.
How many LEDs can I run in series with the ELG-240-C1050B?
The driver operates in constant current mode at 1050mA with an output voltage range of 114–228V. The number of LEDs you can place in series depends on each LED's forward voltage; divide the available voltage range by your LED's Vf to determine the minimum and maximum series count.
What dimming method does the ELG-240-C1050B support?
The 'B' suffix designates built-in PWM signal dimming (0–10V or PWM/resistance). This allows the output current to be adjusted downward from full 1050mA output for dimming without colour-temperature shift common in analogue methods.
How does the ELG-240-C1050B differ from the ELG-240-C1050 and ELG-240-C1050D2?
All three are 240W constant-current drivers at 1050mA. The base ELG-240-C1050 has no built-in dimming. The ELG-240-C1050B adds PWM/0–10V dimming. The ELG-240-C1050D2 is fixed-output with no dimming and a slightly different CC voltage range (100–228V per its spec sheet).
Can this driver be installed in a cold storage or freezer room environment?
Yes. The ELG-240-C1050B is rated for operation down to -40°C, which covers standard cold storage and freezer environments. The IP67 rating also protects against condensation that can occur when equipment is moved between temperature zones.
