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.
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. 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 output of the Mean Well PLC-45-48?

The PLC-45-48 is rated for 45.6W output with a nominal 48V DC output. Its rated current is 0.95A, making it suitable for 48V applications that fit within that power and current range.

What types of applications is the PLC-45-48 designed for?

This model is described as suitable for LED lighting and moving sign applications. Its constant-voltage design with built-in constant-current limiting also makes it relevant for buyers looking for a protected 48V power supply in those categories.

Does the Mean Well PLC-45-48 include power factor correction?

Yes, this model includes built-in active PFC. The listed specification states PF above 0.92 at 115VAC and above 0.9 at 230VAC at full load, which can be important for commercial and OEM purchasing requirements.

Can the output voltage or current be adjusted on the PLC-45-48?

Yes, output voltage is adjustable from 43.6 to 51.8V via SVR1 and the constant current level from 0.713 to 0.979A via SVR2 on the PCB. That gives some flexibility when selecting this model for a 48V application, while still staying within the unit's rated operating range.

What operating temperature range is specified for the PLC-45-48?

The specified operating temperature range is -30°C to 50°C. Buyers evaluating this unit for indoor or enclosure-based use should confirm their environment stays within that stated range.

Does the PLC-45-48 support dimming control?

No dimming control is listed for this model. If your project requires dimming, this is a point to verify carefully against alternative LED driver options before purchase.
