The covers of the PLC series have two small holes with rubber stoppers that users can adjust the output current or voltage without removing the covers. The output current level of PLC-45 series can be adjusted between 75% and 100% of rated value, the output voltage can also be adjusted to between 85% and 100% of rated value.
The Mean Well PLC-45 series is also a limited power source complying with UL 1310 class 2 that under any situation the output power will always be less than 100VA or 5A. The efficiency of the PLC-45 series is up to 87.5% and can operate at between -30° to +50° free air convection.
With active PFC function, the PLC-45 series complies with the regulations for harmonic current of lighting equipment EN61000-3-2 Class C for 75% of output load or higher. Worldwide safety certificates are as follows: UL, CUL, TUV, and CE, including EN61347-2-13, UL1310 Class 2, and UL879 (UL Sign Components Manual/SAM List – PLC-100) for LED lighting / sign board related installations.
