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 75℃ 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-150-C2100B for LED downlights that need a constant-current driver?

Yes, if the downlight is designed for constant-current operation at 2100mA and its LED load falls within the 36-72V constant-current range. This model is a 151.2W constant-current driver, so it is suited to higher-power LED downlight assemblies rather than constant-voltage 24V or 48V fixtures.

Is this driver suitable for powering signage LED modules?

It can be used for signage modules only when the modules are built as a constant-current load at 2100mA and operate within 36-72V. It is not a constant-voltage power supply, so it is not the right match for signage products that expect a fixed 12V, 24V, or 48V input.

Can the ELG-150-C2100B run a small LED array for architectural or display lighting?

Yes, it can run a small LED array when the array is specified for 2100mA constant current and the total forward voltage stays within 36-72V. With 151.2W output capability and an IP67 rating, it fits higher-output LED arrays used in demanding indoor or outdoor environments.

Will this LED driver work outdoors or in wet locations?

This unit is rated IP67 waterproof and has a case temperature (Tcase) rating of -40°C to +90°C. That makes it appropriate for outdoor or washdown-prone environments where a sealed driver is required.

What is the difference between the ELG-150-C2100B and other ELG-150 constant-current versions?

Within the ELG-150-C constant-current family, the main differences are output current and constant-current voltage range: ELG-150-C500 is 500mA, 150–300V (150W); ELG-150-C700 is 700mA, 107–214V (149.8W); ELG-150-C1050 is 1050mA, 72–143V (150.15W); ELG-150-C1400 is 1400mA, 54–107V (149.8W); ELG-150-C1750 is 1750mA, 43–86V (150.5W); and ELG-150-C2100 is 2100mA, 36–72V (151.2W). The ELG-150-C2100B specifically provides 2100mA output with a 36-72V constant-current range.
