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 the LDC-80DA be used with DALI-controlled LED downlights?

Yes, if the downlight uses a constant current LED engine and the LED load operates within the 27-56V range. This is the 80W DALI version with a 700-2100mA adjustable output (1400mA default), so it is intended for constant current lighting systems rather than constant voltage products.

Is the LDC-80DA appropriate for linear LED arrays in commercial fixtures?

It can be used for linear LED arrays when the array is a constant current load that fits the 27-56V CC range. The 80W rating and slim 360.0 × 30.0 × 21.0 mm form factor make it suited to longer, narrow fixture housings.

Can I use the LDC-80DA for constant current signage lighting?

Yes, when the signage lighting uses constant current LED modules within the 27-56V output range and up to 80W. It is not a constant voltage driver, so it is not intended for standard constant voltage signage modules.

What should I check before pairing LEDs with the LDC-80DA?

The LED load must be specified for constant current operation and must stay within the 27-56V CC output range at a current within 700-2100mA (1400mA default, set by resistor on IADJ). The number of LEDs depends on the forward voltage of each LED, so the load should be evaluated by total forward voltage instead of an assumed LED count.

How is the LDC-80DA different from other LDC family 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, with resistor current setting on IADJ and NTC temperature compensation. The LDC-80B adds 3 in 1 dimming (0-10VDC, 10V PWM or resistance), while the LDC-80DA adds a DALI interface (IEC62386-101/102/207) and primary-side push dimming.
