18 outputs, each with fuse
1. The current of 18 groups is not evenly distributed. The value of a single group shall not exceed the installed fuse, and the total current output shall not exceed the rated current of the built-in switching power supply; When a large current is required, two adjacent wires can be connected together (for example, 1 + is connected to 2 +, 1 - is connected to 2 -, and then recognize one output, that is, the load is connected to 1 + and 1 - or the load is connected to 2 + and 2 -), so that the allowable current can be doubled.
2. Output short circuit protection: when a short circuit occurs in a circuit, the self reset fuse of the circuit will fuse and the corresponding indicator light will go out. When the fault is eliminated, replace the fuse with a new one; Generally, there will be 2-3 spare fuse tubes for shipment.
3. Output over-current protection: when a certain circuit of output is under overload condition, the self reset fuse of the circuit will fuse and the corresponding indicator light will go out. When the fault is eliminated, replace the fuse with a new one;
4. Over-voltage protection: when the circuit fails and the output voltage is too high, the power supply will automatically breakdown the zener diode at the output end to protect the subsequent equipment from damage
5. There is an iron box with lock, strong current is not exposed, and the safety is very high.
Precautions for use of switching power supply:
1) The power line of the metal shell and the shell are generally connected to the ground (FG), which shall be reliably grounded to ensure safety, and the shell shall not be connected to the zero line by mistake.
2) Before power on test run after installation, please check and calibrate the wiring on each wiring terminal again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative voltage and current values are correct before power on operation.
3) For high-power power supply, there are generally three or more "+" input terminals and "-" output terminals. In fact, they belong to the same output polarity, just for the convenience of users.
