2. Current adjustment: turn the "a" knob to adjust the current output, press the "a" knob, and the corresponding prompt lamp for adjusting the borrowed current will flash.
3. Four memory buttons, one second to read, three seconds to store, at the same time can store voltage, current, continuous over-current / word over-current / protection settings.
4. The voltage and current are stable and reliable, and there is no peak output. In the constant current and constant voltage mode, the current and voltage will not be touched when they are received.
5. The ring transformer can work at high temperature without affecting the service life of the power supply.
6. Over current protection setting, more stable protection of the machine.
