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 75℃ 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-40-30 for 30V LED lighting applications?

Yes, if the LED lighting product is designed for 30V input and the total load is within 40.2W. This model provides 30V output at up to 1.34A, so both the voltage match and the full connected load need to be checked.

Is the LPF-40-30 suitable for 30V sign lighting?

It can be used for 30V sign lighting products that stay within the 40.2W rating. Its IP67 Waterproof housing also supports applications where the driver may be exposed to outdoor moisture.

Can this model power 30V outdoor decorative or architectural lighting?

Yes, for 30V decorative or architectural lighting loads up to 40.2W. The IP67 rating and -40°C to +80°C case temperature (Tcase) range make the driver itself suitable for wet and exposed environments.

How much 30V LED strip can the LPF-40-30 run?

Maximum strip length is calculated as 40.2W divided by the strip's rated watts per meter. Check your strip rated power per meter, make sure it is a 30V strip, and keep the total strip load at or below 40.2W.

Is the LPF-40-30 appropriate for outdoor or wet locations?

Yes, the IP67 Waterproof rating means the driver is intended for wet and outdoor use. It is also specified for a case temperature (Tcase) of -40°C to +80°C, which supports use across a wide range of weather conditions.

How does the LPF-40-30 compare to the other LPF-40 voltage choices?

In the LPF-40 family, the fixed-output options are 12V at 40.08W and 3.34A, 15V at 40.08W and 2.67A, 20V at 40W and 2A, 24V at 40.08W and 1.67A, 30V at 40.2W and 1.34A, 36V at 40.32W and 1.12A, 42V at 40.32W and 0.96A, 48V at 40.32W and 0.84A, and 54V at 41.04W and 0.76A. The family is similar in form factor and protection level, but each version changes the output voltage and available current.
