Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
9. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-100-C1400AB drive LED modules in a dimmable retail display fixture?

Yes. The ELG-100-C1400AB supports both output current adjustment via a built-in potentiometer and external dimming through its 'B' dimming interface, making it well suited for retail display fixtures where light level control is required. It delivers a constant 1400mA at up to 100.8W with a 35–72V output range that adapts to the forward voltage of the LED string. The IP65 rating allows use in enclosed fixture bodies in conditioned retail spaces.

Is the ELG-100-C1400AB appropriate for powering LED arrays in indoor architectural installations that require dimming?

Yes, the ELG-100-C1400AB is designed for constant current LED loads and supports 0–10V, PWM or resistance-based dimming, making it a practical choice for indoor architectural lighting where dimming scenes are controlled. Its 35–72V output voltage range accommodates LED strings of varying forward voltages, and the 100.8W capacity suits medium-power architectural fixtures. Its case temperature (Tcase) rating is -40°C to +90°C.

Can I use the ELG-100-C1400AB for LED signage modules that require adjustable drive current?

Yes. The adjustable potentiometer on the ELG-100-C1400AB allows the output current to be set to match the LED signage module's rated drive current within the supported 700–1400mA range, reducing the need for ballast resistors or additional current-limiting components. Its constant current output maintains stable brightness even as LED forward voltage shifts with temperature. At 100.8W and 1400mA, it supports medium-scale signage LED arrays.

How many LEDs can the ELG-100-C1400AB drive in a single string?

The ELG-100-C1400AB operates across an output voltage range of 35–72V in constant current mode at 1400mA. The number of LEDs that can be placed in series depends on the forward voltage (Vf) of each individual LED — there is no single LED count that applies universally. Sum the Vf values of all LEDs in the series string and verify the total falls within the 35–72V operating range.

What is the difference between the ELG-100-C1400AB and the ELG-100-C1400A?

Both the ELG-100-C1400AB and ELG-100-C1400A are adjustable constant current drivers rated at 100.8W, 1400mA, with a 35–72V output range and IP65 rating. The ELG-100-C1400AB adds an external dimming input (the 'B' function) on top of the built-in potentiometer adjustment, allowing integration with dimming controllers. The ELG-100-C1400A provides potentiometer adjustment only, without external dimming capability.

Is the ELG-100-C1400AB safe to install in a partially exposed outdoor enclosure?

The ELG-100-C1400AB carries an IP65 rating, protecting it against dust ingress and water jets from any angle, which is acceptable for partially sheltered outdoor enclosures such as under eaves or inside weatherproof sign cabinets. It is not rated for direct water immersion. If full waterproofing is needed, the ELG-100-C1400B with IP67 rating would be more appropriate.
