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 70℃ 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-35DA be used for DALI-controlled LED downlights?

Yes, if the downlight is designed for constant current operation within the 300-1000mA adjustable output range (700mA default) and the LED load is within the 27-56V constant current range. This is a 35W constant current driver with a DALI interface compliant with IEC62386-101/102/207, so it is intended for LED loads that require regulated current rather than constant voltage.

Is the LDC-35DA suitable for signage modules in a DALI lighting system?

It can be, provided the signage module is a constant current LED load that operates between 300 and 1000mA within 27-56V. It should not be treated like a constant voltage power supply, because this model is designed to regulate current to the LED load.

Can I use this driver for a small LED array in a DALI-based fixture?

Yes, if the array is designed for constant current drive within the 300-1000mA adjustable range and its total forward voltage stays inside the 27-56V range. That makes it suitable for small LED arrays in fixtures that need a constant current driver instead of a constant voltage source.

How do I size an LED load for the LDC-35DA?

Match the LED load to a constant current setting between 300 and 1000mA (700mA default, selected with a resistor on the IADJ terminals) and keep the total forward voltage within the 27-56V CC output range. The number of LEDs depends on the forward voltage of each LED, so the correct match is based on current and combined forward voltage, not a specific LED count.

Is the LDC-35DA suitable for harsher ambient conditions?

This model has a case temperature (Tcase) range of -25°C to +80°C, and the output load must be derated at higher temperatures according to the output load vs temperature curve. No IP rating is listed in the provided specs, so environmental suitability should be judged together with the enclosure and fixture design.
