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-80DA2 for LED downlights that need a constant current driver?

Yes, if the downlight is designed for constant current operation within the 700-2100mA adjustable range (1400mA default) and its LED load stays within the 27-56V constant current range. This is an 80W driver, so it is suited to higher-power downlight assemblies within that voltage window. It is not the right choice for fixtures that require a constant voltage driver.

Is the LDC-80DA2 suitable for powering signage LED modules?

It can be suitable for signage modules only when the module assembly is a constant current load within the 700-2100mA output range (1400mA default) and falls within the 27-56V CC output range. Many signage products use constant voltage power instead, so this driver should only be used with modules specified for constant current operation. Its 80W rating supports larger constant current signage assemblies.

Can this driver run a small LED array for architectural or display lighting?

Yes, if the LED array is a constant current design within the 700-2100mA range (1400mA default) and the total forward-voltage requirement lands between 27V and 56V. The exact number of LEDs depends on the forward voltage of each LED, not on the driver alone. Its constant power mode design and 3.0% max. low-frequency current ripple are useful where stable light output is important.

How do I know if my LED load is compatible with the LDC-80DA2?

The load must be a constant current LED assembly whose current is within the 700-2100mA adjustable range (1400mA default, set by resistor on IADJ), with a total forward-voltage requirement inside the 27-56V CC range and power of no more than 80W. The number of LEDs depends on each LED's forward voltage, so compatibility is determined by the full LED string voltage rather than a fixed LED count. This model is not intended for constant voltage LED strips or other constant voltage loads.

How does the LDC-80DA2 compare with other LDC series models?

The LDC-80 series datasheet gives every model the same 80W output: 700-2100mA adjustable (1400mA default), a 27-56V constant current region and full power from 1400-2100mA. All versions offer current setting by resistor on IADJ and NTC temperature compensation. The LDC-80B adds 3 in 1 dimming (0-10VDC, 10V PWM or resistance) on DIM+/DIM-, while DA-type models such as this one add a DALI interface (IEC62386-101/102/207) and primary-side push dimming.

Is the LDC-80DA2 appropriate for high-temperature or enclosed lighting equipment?

It is rated for a case temperature (Tcase) of -25°C to +85°C, with output derating at higher temperatures per the output load vs temperature curve, and a typical life of >50000 hours when Tcase is about 75°C or less. No IP rating is listed in the provided specs, so environmental sealing should come from the finished luminaire or enclosure rather than the driver itself. Its slim 360 × 30 × 21 mm form factor can help where space is limited.
