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 Mean Well LPF-16-12 for 12V LED strip lights outdoors?

Electrically yes: this model has a 12V output with up to 1.34A and 16.08W, so it suits 12V LED strips whose total load stays within 16.08W. However, the sheet lists the standard unit as IP30, with IP67 only as an option, so it is not rated for outdoor or wet-location use as standard.

Is the LPF-16-12 a good fit for a small 12V LED sign or channel letter project?

It can be a fit for small 12V LED signage where the total power draw does not exceed 16.08W. The unit works in constant voltage mode at 12V or constant current mode within 6.6-12V, and is listed as IP30 as standard (IP67 optional), so the driver should be kept protected from moisture.

Can this power supply be used for 12V architectural or accent lighting in damp areas?

It can power 12V LED lighting loads up to 16.08W for low-power accent or architectural lighting, but not in damp areas as standard: the sheet lists the standard unit as IP30, with IP67 only as an option. The working case temperature range is -35°C to +70°C.

How much 12V LED strip can the LPF-16-12 run?

The maximum output power is 16.08W, so the strip length depends on your strip's rated power per meter. Use this formula: 16.08W ÷ your strip watts per meter = maximum estimated length, and check your strip rated power per meter before sizing.

Is the Mean Well LPF-16-12 waterproof and suitable for outdoor conditions?

No, not as standard. The sheet lists the standard unit as IP30, with IP67 only as an option, so it is not waterproof or rated for outdoor use. It is rated for a working case temperature (Tcase) of -35°C to +70°C.

What is the difference between the LPF-16-12 and the other LPF-16 series models?

The LPF-16-12 is the 12V version rated at 1.34A and 16.08W. Other LPF-16 models are LPF-16-15 at 15V 1.07A 16.05W, LPF-16-20 at 20V 0.8A 16W, LPF-16-24 at 24V 0.67A 16.08W, LPF-16-30 at 30V 0.54A 16.2W, LPF-16-36 at 36V 0.45A 16.2W, LPF-16-42 at 42V 0.39A 16.38W, LPF-16-48 at 48V 0.34A 16.32W, and LPF-16-54 at 54V 0.3A 16.2W. All share the same 90-305VAC input and 148*40*32mm case.
