Function Description
1. Items 1 – 5 in the technical parameters are controlled by independent contactors. Before the output terminals, 10A and 20A air switches are connected in series as short-circuit protection. According to special user requirements, items 1 – 5 can be closed simultaneously without interlocking. Please pay attention to the requirements during use.
Only one set of power output can work at a time.
2. Items 6 – 7 in the technical parameters are not controlled by contactors. As long as the main power switch is closed, single-phase AC220V output (fixed value) and three-phase AC380V output (fixed value) can be output.
3. The three-phase transfer switches K1, K2, K3 control the three-phase AC380V voltmeter, three-phase AC ammeter, and three-phase AC voltmeter on the panel respectively.
Operating Instructions
Taking the verification of a single-phase AC voltmeter as an example:
1. Connect the input power AC380V
2. Connect the AC operating voltage output power line to the voltmeter
3. Check and confirm whether the wiring is correct, then 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 operating 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 operating voltage on the panel, then press the main "Open" button on the panel. Then, turn off the main power switch
