These limited power sources comply with UL 1310 class 2 that under any situation the output power will remain 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. The IP64 enclosure design can protect the electronic components against dust and moisture and makes them suitable for use at indoor or outdoor locations. Thanks to the simplified single stage PFC topology, the required high power factor, as well as the class C harmonic level for the lighting industry, can be achieved economically. Efficiency’s of PLN-30 series are as high as 86% and hence can operate between -30°C ~ +50°C by only free air convection inside the fully covered plastic enclosure. Standard functions include short circuit, over load, over voltage, and over temperature protections. The adjustable output voltage and current level enables the fine tuning of the PSU to comply with the requirement of LED characteristics
