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).
10. 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-90-48 for 48V LED signage or lightbox lighting?

It can be used for 48V LED signage or lightbox lighting if the load matches the 48V output and stays within 90.24W. This is a constant voltage + constant current driver with a 28.8-48V constant current region, so the lighting load should be specified inside that range.

Is the LPF-90-48 suitable for 48V linear or cove lighting fixtures?

Yes, it suits 48V linear or cove lighting fixtures that require up to 1.88A and no more than 90.24W. The connected fixture should be designed for the driver's 28.8-48V constant current region.

Can this driver be used for outdoor 48V architectural lighting?

Yes, the LPF-90-48 has an IP67 rating and operates at a case temperature (Tcase) of -40°C to +70°C, with load derating at higher temperatures, which supports outdoor architectural lighting use. The load still needs to match the 48V class and stay within 90.24W.

How much 48V LED strip can the LPF-90-48 support?

The available power is 90.24W, so the maximum strip length is 90.24W divided by the strip's watts per meter. In other words, length = 90.24W / rated W per meter. Check your strip rated power per meter so the total load does not exceed 90.24W.

Is the LPF-90-48 rated for wet locations?

Yes, it is rated IP67 and operates at a case temperature (Tcase) of -40°C to +70°C, with load derating at higher temperatures. That makes it suitable for wet lighting projects where those limits match the site conditions.

How does LPF-90-48 differ from the other LPF-90 output options?

In the LPF-90 group, the available outputs are 15V 75W 5A, 20V 90W 4.5A, 24V 90W 3.75A, 30V 90W 3A, 36V 90W 2.5A, 42V 90.3W 2.15A, 48V 90.24W 1.88A, and 54V 90.18W 1.67A. All models share the 90-305VAC input range and the same 161*61*36mm case.
