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".
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 power supply 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 85℃ 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-200-C2100AB be used for tunable or dimmable LED downlights in an office fit-out?

Yes. The AB suffix indicates this model supports both output adjustment and 3-in-1 dimming (0–10VDC, 10V PWM or resistance). It can be connected to a 0–10V dimming interface commonly found in office lighting control systems to dim connected LED downlights at 2100mA constant current down to a minimum level of about 8%.

Is the ELG-200-C2100AB appropriate for outdoor LED signage cabinets?

The ELG-200-C2100AB is rated IP65, providing complete dust exclusion and resistance to low-pressure water jets. It is suitable for sign cabinets but is not rated for temporary immersion. Where immersion protection is needed, the IP67 variants in this series are more appropriate.

Can this driver power LED arrays in stage or architectural accent lighting with dimming requirements?

Yes. The adjustable and dimmable ELG-200-C2100AB supports analog dimming, making it compatible with stage lighting rigs and architectural accent systems that use 0–10V or PWM control. Its 201.6W output at 2100mA and a CC voltage range of 48–96V accommodate medium to large LED arrays.

How does the adjustable feature of the ELG-200-C2100AB help during LED fixture commissioning?

The built-in output adjustment potentiometer allows the installer to fine-tune the constant current output between 1050mA and 2100mA during commissioning to match the connected LED string. This avoids relying solely on the nominal 2100mA rating and allows brightness calibration without external components.

How many LEDs can be run in series from the ELG-200-C2100AB?

The CC voltage range of the ELG-200-C2100AB is 48–96V. The number of LEDs per string depends on the forward voltage of each LED; the total combined forward voltage of the series string must fall within 48–96V for the driver to regulate properly at 2100mA.

What is the difference between the ELG-200-C2100A and ELG-200-C2100AB?

Both models share the same 201.6W output, 2100mA constant current, 48–96V CC voltage range, IP65 rating, and adjustable output potentiometer. The ELG-200-C2100AB adds 3-in-1 dimming capability (the B designator), making it compatible with 0–10V, PWM or resistance dimming, while the ELG-200-C2100A has no dimming input.
