Frequently Asked Questions
Can the ELG-100-C1050AB be used in a dimmable LED downlight system controlled by a 0-10V wall dimmer?
Yes. The 'AB' suffix indicates both dimming capability and an analog output-adjustment interface. The driver supports 0-10V (as well as PWM and resistance) dimming signals, making it compatible with standard 0-10V architectural dimming systems.
Is the ELG-100-C1050AB suitable for LED retail signage that needs both field-adjustable brightness and remote dimming?
Yes. The combination of output adjustment (A) and dimming (B) in this model lets system designers set a base output level and then dim the sign from a central controller. The driver operates at 1050mA constant current with a CC range of 48–95V.
What IP rating does the ELG-100-C1050AB carry for semi-outdoor installations?
The ELG-100-C1050AB is rated IP65, protecting against dust ingress and low-pressure water jets. It is suitable for covered outdoor enclosures and sign cabinets but is not intended for direct rain exposure without additional housing protection.
What LED string voltages are compatible with the ELG-100-C1050AB?
The constant current output voltage range is 48–95V. Any series-connected LED string whose combined forward voltage falls in that range is compatible; the LED count per string depends on each LED's forward voltage.
Can the ELG-100-C1050AB operate on both residential 120V and commercial 277V AC supplies?
Yes. The universal input of 100–305VAC covers both 120V residential and 277V commercial single-phase supplies used in North America, as well as 230V European grids.
How does the ELG-100-C1050AB differ from the ELG-100-C1050B?
Both share the same 99.75W / 1050mA / 48–95V CC specifications and IP65 rating. The ELG-100-C1050B provides dimming only, while the ELG-100-C1050AB adds an output-adjustment trim interface in addition to the dimming function.
