Frequently Asked Questions
Can the ELG-100-C1050B be used to dim LED downlights via a standard PWM dimming signal?
Yes. The 'B' variant supports 3-in-1 dimming, meaning it accepts PWM, resistance, and 0-10V dimming signals. This makes it compatible with a wide range of commercial and architectural dimming controllers.
Is the ELG-100-C1050B appropriate for outdoor LED luminaires exposed to rain?
Yes. The ELG-100-C1050B carries an IP67 waterproof rating, meaning it can withstand temporary immersion and is well suited for outdoor luminaires, wall-wash fixtures, and area lighting exposed to rain.
Can I use the ELG-100-C1050B to power a dimmable LED display panel in a commercial space?
Yes. At 99.75W and 1050mA constant current, this driver supports mid-power LED display panels. The built-in dimming interface allows brightness control through a building automation or lighting control system.
What is the compatible LED string voltage range for the ELG-100-C1050B?
The driver operates in constant current mode with a CC output voltage range of 48–95V. Series-connected LED strings with combined forward voltages within this range are compatible; the number of LEDs per string depends on each LED's individual forward voltage.
Will the ELG-100-C1050B work in a hospitality dimming scene where lamps need to fade smoothly?
Yes. The 3-in-1 dimming feature of the ELG-100-C1050B supports smooth analog dimming curves when driven with a 0-10V or PWM signal, making it well suited for hotel, restaurant, or lobby lighting scenes requiring gradual transitions.
How does ELG-100-C1050B compare to the ELG-100-C1050 base model?
The ELG-100-C1050 is a fixed-output driver with no dimming interface, while the ELG-100-C1050B adds 3-in-1 dimming (PWM, resistance, 0-10V). Both are rated 99.75W / 1050mA / IP67 and share the same 48–95V CC output range.
