MEAN WELL introduced the new PLC-30/60/100 LED power supply series for the emerging demand of LED lighting / decorative lighting applications. Modified from the existing PLN-30/60/100, the new plastic cases of PLC family are redesigned to change to terminal block style of I/O connection which provides more flexibility to the wiring job. The covers of PLC family also add on two small holes with rubber stoppers that users can adjust the output current or voltage of PLC-30/60/100 easily without removing the covers. Through the potential meters, output current level of PLC family can be adjusted between 75% and 100% (or 75~103%) of rated value while the output voltage can be adjusted between 85% and 100% (or 95~110%) of rated value. PLC-30/60/100 series are also limited power sources complying with UL 1310 class 2 that under any situation the output power will less than 100VA or 5A. This will significantly reduce the hazardous condition exposed to the technicians who execute the construction or maintenance of the LED lighting system.
Thanks to the leading edge ZCS/ZVS technology, the efficiency of PLC family are as high as 89% and hence can operate between -30 ~ +50¢J by only free air convection. Building in active PFC function, the PLC family complies with the limitation of harmonic current of lighting equipment per EN61000-3-2 Class C for 75% of output load or higher. Besides, the power factor (PF) value will higher than 0.9 also when the output loading is 75% or higher. Other characteristics include CC+CV mode output style and short circuit, overload, over voltage, and over temperature protections. PLC-30/60/100 also comply with global safety certificates per UL, CUL, TUV, and CE, including EN61347-2-13, UL1310 Class 2, and UL879 (UL Sign Components Manual/SAM List ¡V PLC-100) for LED lighting / sign board related installations. Typical applications for these new Class 2 power units are moving signs and backlighting, LED-based decorative/architectural lighting, LED stage and theater lighting, and LED electronic displays.
