4. AC operation voltage output
AC 0 - 400V, at 220V, current less than 10A one set
5. DC operation voltage output DC 0 - 260V one set
6. DC closing power supply output DC 0 -250V (300A, short-time operation) one set
7. Single-phase AC220V output (fixed value, socket form) two sets
8. Three-phase AC380V output (fixed value, terminal post) one set
9. Closing control contacts ⑤, ⑧ opening control contacts ⑥, ⑦
10. Fixed value output: DC24V, 36V, 110V
11. Dimensions/Weight: 550×750×800mm/45Kg
Taking the verification of a single-phase AC voltmeter as an example:
1. Connect the input power AC380V
2. Connect the AC operation voltage output power line to the voltmeter
3. Check and confirm whether the wiring is correct, turn on the main power switch
4. Return the voltage regulator to zero, and press the "close" button,
5. Then press the "close" button for AC operation voltage on the panel
6. Slowly adjust the output adjustment knob to raise the voltage to the required value, and observe the voltmeter.
7. After the test, first press the "open" button for AC operation voltage on the panel, then press the main "open" button on the panel. Then, disconnect the main power switch
