Test conditions and notes11
  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. 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

What is the Mean Well PLC-45-20 designed for?

The PLC-45-20 is a 45W power supply intended for LED lighting and moving sign applications. It provides a 20V output and includes a built-in constant current limiting circuit for C.V.+C.C. operation.

What are the key electrical specs of the PLC-45-20?

This model is rated for 45W class output, with a nominal 20V output and 2.3A rated current. It also includes adjustable output voltage and current level, which can help match the power supply to application requirements within the product's designed range.

Does the PLC-45-20 include power factor correction?

Yes. The PLC-45-20 has built-in active PFC, with PF above 0.92 at 115VAC and above 0.9 at 230VAC at full load according to the datasheet. That makes it a relevant option for buyers looking for a power supply with active power factor correction.

What protection features are included in the PLC-45-20?

The PLC-45-20 includes protections for short circuit, over current, over voltage, and over temperature. It is also certified to UL1310 and carries the LPS mark, which can matter for commercial LED power applications.

What operating temperature range is this power supply rated for?

The specified operating temperature range is -30°C to 50°C. Buyers should confirm that the expected ambient conditions for their project stay within that range for reliable performance.

Is the PLC-45-20 a dimmable LED driver?

No. The provided product data lists dimming control as none, so this model is not positioned as a dimming power supply. It is better suited for applications that need a fixed-output 20V power supply rather than integrated dimming control.
