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 I use the ELG-100-C1400A to power LED downlights in a commercial retrofit project?

Yes. The ELG-100-C1400A delivers a constant 1400mA output up to 100.8W, making it suitable for driving higher-power LED downlight arrays used in commercial retrofits. Its operating voltage range of 35–72V accommodates a variety of LED module configurations depending on the forward voltage of the LEDs selected. The IP65 water-resistant rating also allows installation in damp or humid ceiling environments.

Is the ELG-100-C1400A suitable for outdoor LED signage applications?

The ELG-100-C1400A carries an IP65 water-resistant rating, which provides protection against dust ingress and low-pressure water jets, making it appropriate for outdoor LED signage cabinets with adequate enclosures. It accepts a wide input range of 100–305VAC and has a case temperature (Tcase) rating of -40°C to +90°C, supporting a range of outdoor climates. For fully exposed or submersible outdoor installations, the IP67-rated ELG-100-C1400B may be a better fit.

Can this driver power a series string of LED modules in an architectural lighting cove?

Yes, the ELG-100-C1400A is a constant current driver that maintains a fixed 1400mA output, which is well suited for series-connected LED module strings used in cove or linear architectural lighting. The output voltage self-adjusts within the 35–72V range to match the combined forward voltage of the LED string. The number of modules that fit in series depends on the forward voltage of each individual LED module.

What adjustment capability does the 'A' suffix provide on the ELG-100-C1400A?

The 'A' suffix indicates the driver includes a built-in potentiometer that allows the output current to be trimmed between 700mA and 1400mA, giving installers the ability to fine-tune light output without replacing the driver. This is useful when matching output to LEDs with specific current tolerances or when a reduced output level is needed without an external control interface. It operates in constant current mode and does not support external dimming signals.

Can the ELG-100-C1400A be installed in wet or wash-down locations?

The ELG-100-C1400A is rated IP65, meaning it is protected against dust and low-pressure water spray from any direction. It is suitable for damp locations and covered outdoor areas, but not for direct water immersion or high-pressure wash-down environments. For those conditions, the IP67-rated variant ELG-100-C1400B provides a higher level of water ingress protection.

How does the ELG-100-C1400A differ from the ELG-100-C1400B and ELG-100-C1400AB within the same family?

All three variants share the same 100.8W output, 1400mA constant current, 35–72V operating range, and 199×63×35.5mm form factor. The ELG-100-C1400A (this unit) is adjustable via a built-in potentiometer and carries an IP65 rating. The ELG-100-C1400B is dimmable via external signal and is rated IP67. The ELG-100-C1400AB combines both adjustability and external dimming and is also rated IP65.
