Frequently Asked Questions
Can the ELG-240-C2100B be used for LED lighting in a fully outdoor, rain-exposed fixture?
Yes. The ELG-240-C2100B carries an IP67 rating, which means it is protected against temporary water immersion up to 1 metre, making it appropriate for fully outdoor fixtures exposed to rain. It also operates from -40°C to +85°C, covering demanding outdoor temperature ranges. Its metal enclosure provides additional mechanical protection.
What types of LED lighting applications suit the ELG-240-C2100B?
At 241.5W and 2100mA constant current with a 57–115V output range, the ELG-240-C2100B is well-matched for medium-to-large LED downlight arrays, high-bay LED modules, and outdoor LED area lighting fixtures. The IP67 rating extends its use to wet and outdoor environments where lower IP-rated drivers would not be appropriate.
How many LEDs can be driven in series by the ELG-240-C2100B?
The driver outputs 2100mA constant current with an adjustable voltage range of 57–115V. The number of LEDs in a series string depends on each LED's forward voltage — the sum of forward voltages must fall within the 57–115V range. No specific LED count applies universally.
What dimming interface does the ELG-240-C2100B use?
The 'B' suffix indicates this model supports analog dimming via a 0–10V signal, PWM signal, or resistance control. This allows integration with standard commercial and industrial lighting control systems. For DALI-based building automation, the ELG-240-C2100DA would be required instead.
How does the ELG-240-C2100B compare to the ELG-240-C2100A within the same series?
Both share 241.5W output, 2100mA constant current, and a 57–115V CC range. The ELG-240-C2100A is IP65 and provides output adjustability without dimming. The ELG-240-C2100B is IP67 and adds analog dimming (0–10V / PWM / resistance) but without the adjustable trim of the 'A' variant. Select based on IP requirement and whether you need dimming or current trim.
Is the ELG-240-C2100B approved for use in North American and European installations?
Yes. The ELG-240-C2100B holds certifications including UL, CB, CE, CCC, ENEC, EAC, c_bsi, and c_rcm, covering major markets in North America, Europe, Australia, and Asia. The 100–305VAC input range accommodates all common supply voltages in these regions.
