Test conditions and notes9
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
- 2. Please refer to " OUTPUT CURRENT SETTING ".
- 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 >50000 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. 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.

FAQ
Can I use the LDC-80B for dimmable LED downlights that run on constant current?
Yes, when the LED downlight is a constant current load within the 27-56V output range and up to 80W. This version is the 3 in 1 dimming (0-10VDC, 10V PWM or resistance) 80W model, so it fits constant current downlight applications where that control style is needed.
Is the LDC-80B suitable for LED arrays in slim architectural fixtures?
It can be a fit for slim fixture builds that use constant current LED arrays operating from 27-56V. The driver body is 360.0 × 30.0 × 21.0 mm, so the narrow 30mm format supports long, low-profile fixture layouts.
Can this driver be used for signage modules with dimming requirements?
It can be used only if the signage module is a constant current LED assembly that operates within 27-56V and up to 80W. It should not be used in place of a constant voltage power supply for 12V or 24V signage systems.
How do I confirm LED compatibility with the LDC-80B?
Check that the LED load requires a constant current source and that its operating voltage falls within the 27-56V CC range at the required current. The number of LEDs depends on each LED's forward voltage, so there is no single fixed LED count for this driver.
Can the LDC-80B operate in demanding ambient temperatures?
The specified working temperature is a case temperature (Tcase) of -25°C to +85°C, with output derating at higher temperatures per the output load vs temperature curve. No IP rating is listed in the provided specs, so exposure conditions should be judged at the fixture or enclosure level.
