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-16-48 for a 48V constant-current LED sign?

Yes, if the sign uses a constant-current LED load at 0.34A and its forward voltage falls within the 26.4-48V constant-current region. The driver provides up to 16.32W, so it is suited to smaller 48V sign sections rather than larger illuminated displays.

Is this a good choice for slim 48V linear LED lighting modules?

It can be used with slim linear modules that are specified for 0.34A constant current and stay within 26.4V to 48V. Its 16.32W output makes it appropriate for compact or low-power linear lighting sections.

Can the LPF-16-48 be used for outdoor accent lighting?

Not as standard: the sheet lists the standard unit as IP30, with IP67 only as an option, so this version is not rated for outdoor or wet-location use. Its working case temperature is Tcase -35°C to +70°C, and the fixture needs to be a 0.34A constant-current load within 26.4-48V.

Would this driver work for a small 48V LED display fixture?

Yes, if the display fixture is designed for constant-current operation at 0.34A. The driver's 16.32W capacity fits smaller 48V display fixtures and compact illuminated elements.

How do I estimate the maximum 48V LED strip length for the LPF-16-48?

Use this formula: maximum strip length = 16.32W divided by the strip's rated watts per meter. The driver gives 48V in constant-voltage mode or 0.34A in constant-current mode within 26.4-48V, so check your strip rated power per meter and make sure the strip matches this output.

What is the difference between the LPF-16-48 and other nearby LPF constant-current models?

Within the LPF-16 series, the nearby models are LPF-16-42 at 16.38W, 42V, 0.39A; LPF-16-48 at 16.32W, 48V, 0.34A; and LPF-16-54 at 16.2W, 54V, 0.3A. They share the same 90-305VAC input and 148*40*32mm case; the difference is the output voltage, current and constant-current region.
