SPT 9-Port 5 Amp CCTV Power Supply Box with PTC Fuse

Each output has independent PTC fuse and LED indicator. When problem occurs, it will only affect the independent output. When short condition occurs, independent PTC fuse will open the circuit. When condition is removed, PTC fuse will automatically close. When high voltage occurs, the surge protection will protect the connected device. When over current occurs, the power supply will automatically switch to self-protection status. When condition removed, it will then switch back to normal.
