Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. The power supply 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)
- 5. Suitable for indoor use or outdoor use without direct sunlight exposure.
- 6. This product is not intended for LED applications in the EU and China.(In the EU NPF/LPF/XLG series are recommended.)
- 7. Products sourced from the China regions may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ
Can I use the LPH-18-24 for 24V LED strip lighting?
Yes, this model is a 24V single-output switching power supply, which suits 24V LED strip loads (the sheet notes it is not intended for LED applications in the EU and China). The load should remain within 18W total and 0.75A output current.
Is the LPH-18-24 appropriate for compact 24V sign lighting or cabinet lighting?
Yes, it can be used for small 24V sign lighting or compact lighting runs where a constant 24V output is required. The slim 140 x 30 x 22 mm case is useful where space is limited.
Can this 24V driver be used in outdoor lighting conditions?
Yes, it is fully encapsulated to IP67 and suits indoor use or outdoor use without direct sunlight exposure. The specified operating temperature range is -30°C to +70°C, with output derating at higher temperatures per the derating curve.
How do I estimate LED strip length for the LPH-18-24?
Use the power formula: maximum strip length equals 18W divided by your strip's rated watts per meter. Check your strip rated power per meter and confirm it is a 24V constant voltage strip.
How does the LPH-18-24 compare with the other LPH-18 models?
The specified LPH-18 versions are 12V at 18W and 1.5A, 24V at 18W and 0.75A, and 36V at 18W and 0.5A. This model keeps the same 18W power as the others but sits in the middle on output voltage and current.
