Mean Well USA (Fremont, CA) has modified the existing PLN-30/60/100 and redesigned the PLC-family plastic cases to change to a terminal-block style for the I/O connection to provide more flexibility to the wiring job.
The covers of PLC family also add two small holes with rubber stoppers, which enable users to adjust the output current or voltage of PLC-30/60/100 without removing the covers. Through the potential meters, the PLC family’s output-current level 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, which are also limited power sources, comply with UL 1310 Class 2, which means, under any situation, the output power will be less than 100VA or 5A.
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 – 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.
