Test conditions and notes12
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltage. Please check the static characteristics for more details.
  5. 5. Output voltage can be adjusted through the SVR1 on the PCB ; limit of output constant current level can be adjusted through the SVR2 on the PCB.
  6. 6. Please refer to "DRIVING METHODS OF LED MODULE".
  7. 7. 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)
  8. 8. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  9. 9. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
  10. 10. 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).
  11. 11. 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
  12. 12. This product is not suitable for LED lighting applications in China.(It is recommended to use the LPF/NPF/XLG/XLC/XLN series in China)

FAQ

Can I use the PLN-45-36 for a 36V LED strip or lighting system?

Yes, if the 36V lighting load stays within 45W maximum power and 1.25A maximum output current. The unit operates in constant current mode with a 27-36V range, so the lighting product should be checked for electrical compatibility.

Is the PLN-45-36 suitable for 36V signage lighting?

It can be used for 36V signage applications that require no more than 45W total output. The IP64 enclosure helps in dusty or splash-prone locations.

Can this 36V driver be used for commercial or industrial lighting runs?

Yes, for 36V lighting loads within the 45W and 1.25A limits. The wide 90-295VAC input range and -30°C to +50°C operating temperature range are useful where site power and ambient conditions vary.

How much 36V LED strip can the PLN-45-36 run?

The maximum available output is 45W. To estimate maximum strip length, divide 45W by your strip's rated watts per meter, then confirm the strip is a 36V product and that total current stays at or below 1.25A; check your strip rated power per meter.

Is the PLN-45-36 appropriate for outdoor environments?

It is IP64 rated, so it is intended for dust exposure and splashing water rather than immersion. The specified operating temperature range is -30°C to +50°C, which supports use in cold and hot outdoor conditions within that range.
