1.The currents of groups 1 and 9 are not evenly distributed. The single rent should not exceed the value of the installed fuse. The total current output does not exceed the rated current of the built-in switching power supply. When a large current is required, the adjacent 2 channels can be put together. The current can be doubled;
2. Output short circuit protection: When a short circuit occurs on a certain road, the self-resetting fuse of the road will be blown, and the corresponding indicator light will be extinguished. When troubleshooting, replace the new fuse; we will have 2-3 spare fuses when shipping;
3. Output over-current protection: When the output of a certain road is in an overload condition, the self-resetting fuse of the road will be blown, the corresponding indicator light will be extinguished, and when the fault is eliminated, a new fuse will be replaced;
4. Overvoltage protection: When the circuit fails and the output voltage is too high, the power supply will automatically break through the output terminal voltage diode to protect the equipment of the latter stage;
5, with iron lock box, strong electricity is not exposed, high security!
