General protection: each output has independent PTC fuse and LED indicator, when problem occurs, only affect the independent output, other outputs still working. Circuit short protection: when short condition occurs, independent PTC fuse will open the circuit,when condition removed, PTC fuse will automatically back to close. High voltage protection: when high voltage occurs, the surge protection will be hit through to protect the connected device. Over Current protection: when over current occurs, the power supply will automatically switch to self-protection status, when condition removed, then switch back to normal. Application ： CCTV Camera, PTZ, IR Illuminator, Video Processor， Access Control , etc.
