Variable frequency power source control cabinet: 
1) Equips starting, stop and emergency switch - off button;
2) Equips raise voltage and reduce voltage rough adjustment and fine control button(voltage raise and down speed are settable);
3) Equips frequency rough adjustment and fine control button (Adjusting speed is settable);
4) Cooling fan direction automatically selection;
5) Automatic and manual test selection (Auto tune, automatic raise and reduce voltage);
6) Equip test methods auto selection function, automatic test methods: setting test voltage, test time, auto tune --- auto raise voltage --- auto constant voltage and timing --- auto reduce voltage.
7) Manual test methods also has the selection of auto tune and auto timing;
8) Equips output voltage, over-voltage protection and over-current protection setting value adjusting function;
9) Equips testing time setting function, time setting range:0-99min, timing accuracy±0.1second, end of setting time has sound reminding.
