Test conditions and notes12

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. 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.
7. 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)
8. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
9. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
11. 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).
12. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can I use the LPF-16D-12 for 12V LED strip lighting with dimming?

Yes, if the LED strip or load is designed for constant-current operation at 1.34A within the 6.6-12V range. This model provides up to 16.08W and includes built-in 3 in 1 dimming for small dimmable lighting loads.

Is the LPF-16D-12 suitable for dimmable under-cabinet or display lighting?

It can be suitable for small under-cabinet or display lighting systems when the LED load requires 1.34A constant current and falls between 6.6V and 12V. The 16.08W output and built-in 3 in 1 dimming make it appropriate for low-power dimmable fixtures.

Can this driver be used for dimmable 12V LED signage modules?

Yes, for signage modules that are specified for constant-current operation at 1.34A. The total load must stay within 16.08W and within the 6.6-12V constant-current range.

Would the LPF-16D-12 work for damp or outdoor dimmable lighting?

Not as standard: the unit is rated IP30, so it is not intended for wet or outdoor locations; IP67 is listed only as an option. It works at a case temperature (Tcase) of -35°C to +70°C, and the LED load must match the 1.34A constant-current output and 6.6-12V range.

How do I estimate LED strip length with the LPF-16D-12?

Use the formula: maximum strip length = 16.08W divided by your strip's rated watts per meter. Because this is a constant-current 1.34A driver with a 6.6-12V range, check your strip rated power per meter and confirm the strip is designed for this constant-current output.
