I don't like the above PSU any more, this below is batship.
What is the crazy stuff they want you to do below? Like you have to plug this adjust current plug into the PSU then set you current and shut the PSU off and then remove the plug then turn it on again. Thanks batship.
Operational use
(How to limit current) to adjust current?
1. Operate in the case of power failure, pull the small pull switch in the lower left corner to the current regulating gear
2. Pull out (dedicated current regulating insert) to the 2nd and 3rd ports of the wiring port, loosen the port screw with a screwdriver, and tighten with a screwdriver (at this time, connect to the listed power), and then connect The voltage of the meter shows 0.00V, and the current shows the current current parameter. At this time, the power supply will emit a small current.
3. On the right side (adjust current knob), you can adjust the desired current limit parameter, and display the current parameter synchronously with the digital display. 0-21A/0-16A/0-11A/0-6.5A can be adjusted in the whole process.
4. Remove the (special adjustment current plug) and insert it back into the original insert card holder. After removing the digital display, the voltage is about 0.90V, and the current is 0.00A.
5. Pull the pull switch in the lower left corner to the right to open the "open (use)" position.
6. The current power supply is in the parameter value of the current limit. The power supply is adjusted to a few V (the digital display shows the output voltage in real time), the current does not change, and the current reaches the current limit of 95% of the current limiting parameter. Overload protection
7. The current parameter displayed by the digital display at this time is the current value of the device load, and the load current is monitored in real time.
