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-35B be used for dimmable LED downlights?

Yes, if the fixture is built for constant current operation within the 300-1000mA adjustable output range (700mA default) and the LED load falls within the 27-56V CC range. This is a 35W constant current driver with 3-in-1 dimming (0-10VDC, 10V PWM signal or resistance), so it is for downlights that expect regulated current rather than constant voltage input.

Is the LDC-35B a good match for dimmable signage lighting modules?

It can work for signage modules that are designed as a constant current LED load within 27-56V. Because this model is constant current, it should be paired with signage modules specified for operation between 300 and 1000mA, not constant voltage modules.

Can I use the LDC-35B with a small LED array that needs light control?

Yes, as long as the LED array is a constant current load within the 300-1000mA adjustable range and its total forward voltage stays within 27-56V. This makes it suitable for small LED arrays where dimmable constant current drive is required instead of a fixed-voltage supply.

What should I check before pairing LEDs with the LDC-35B?

Check that the LEDs are intended for constant current operation at a current the driver can be set to (300-1000mA, 700mA default, selected with a resistor on IADJ) and that the full load sits inside the 27-56V constant current range. The number of LEDs depends on each LED's forward voltage, so compatibility should be based on total forward voltage rather than a fixed LED count.

What are the main differences between the LDC-35B and other LDC family models?

LDC-35B shares the 35W rating, 300-1000mA adjustable output (700mA default), 27-56V CC range and 180-295VAC input with LDC-35 and LDC-35DA on this spec sheet. It differs by adding 3-in-1 dimming (0-10VDC, 10V PWM signal or resistance) between DIM+ and DIM-, while the DA-type offers a DALI interface and push dimming instead; other LDC power classes are not covered by this sheet.
