Test conditions and notes11
- 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. Derating may be needed under low input voltage. Please check the static characteristics for more details.
- 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. Please refer to "DRIVING METHODS OF LED MODULE".
- 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. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
- 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.

FAQ
What are the main electrical ratings of the Mean Well PLC-45-27?
The PLC-45-27 is a 45W power supply with a 27V output and 1.7A rated current. It is designed with a universal AC input range and includes active PFC. This model also supports adjustable output voltage and current level within its designed operating range.
What types of applications is the PLC-45-27 designed for?
The PLC-45-27 is a 45W LED power supply suited to LED lighting and moving sign applications. Its built-in constant current limiting circuit in C.V.+C.C. mode makes it a practical choice for applications that benefit from stable 27V output with current limiting behavior. Mean Well suggests driving LEDs directly in its constant current region of 20.25 to 27V.
Does the PLC-45-27 support dimming control?
No, this model does not include a dimming control function. Buyers looking for a driver with integrated dimming should treat the PLC-45-27 as a non-dimming option. Its value is centered more on regulated output, active PFC, and protection features.
What protection features are included on the Mean Well PLC-45-27?
The PLC-45-27 includes protection for short circuit, over current, over voltage, and over temperature. Over voltage protection trips at 31 to 35V and needs a re-power to recover, while the other protections recover automatically. These features are intended to support reliable operation in demanding commercial environments.
What operating temperature range is this power supply rated for?
This model is rated for operation from -30°C to 50°C, with load derating per the datasheet's derating curve. That range makes it suitable for many indoor and protected commercial environments where temperature conditions can vary. Buyers should confirm that the application stays within this stated operating range.
How efficient is the PLC-45-27, and does it include power factor correction?
The PLC-45-27 has a typical efficiency of 86.5%. It also includes an active PFC function, with PF above 0.92 at 115VAC and above 0.9 at 230VAC at full load. This can make it a better fit for applications where power quality and efficiency matter.
