Test conditions and notes9

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
3. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
4. Efficiency is measured at 500mA/50V output set by DIP switch.
5. Standby power consumption is measured at 230VAC.
6. 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)
7. 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).
8. Based on IEC 62386-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which can support for DALI power on function, otherwise the set up time will be higher than 0.5 second for DA2-type.
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 LCM-25DA with dimmable LED downlights?

Yes, the LCM-25DA is a constant current LED driver rated at 25.2W (18.9W at 350mA), with DIP-switch selectable output from 350mA to 1050mA (700mA default, 6-36V at that setting). It is intended for constant current LED downlights and adds DALI and push dimming.

Is the LCM-25DA a good fit for signage modules that need dimming control?

It can be, provided the signage modules are designed for constant current operation instead of constant voltage. This model delivers 700mA by default over 6-36V (selectable 350mA to 1050mA via DIP switch) and is rated up to 25.2W, with DALI and push dimming for controlled dimming.

Can the LCM-25DA power a small constant current LED array?

Yes, for small LED arrays built around a constant current input, the LCM-25DA fits loads within its 6-36V range at the default 700mA setting (other DIP-switch settings from 350mA to 1050mA change the range). Its 25.2W power level makes it appropriate for smaller arrays rather than higher-power constant current assemblies.

How do I match the LCM-25DA to my LED load?

Match it to LEDs that require constant current and whose total forward voltage stays within the DC voltage range of the selected current: 6-54V at 350mA, 6-50V at 500mA, 6-42V at 600mA, 6-36V at 700mA (default), 6-28V at 900mA and 6-24V at 1050mA. Size the load by forward-voltage total, not as a constant voltage driver.

Can the LCM-25DA handle demanding ambient conditions?

It is specified for a case temperature (Tcase) of -30°C to +85°C, with output load derating at higher temperatures per the output load vs temperature curve, which supports enclosed lighting equipment. Environmental suitability still needs to align with the rest of the fixture because the listed specs here focus on temperature, not a separate IP rating.
