12Bit high-speed AD acquisition, 128 wave acquisition points per cycle, digital processing and operation by single chip microcomputer, and rapid compensation by electronic module |
| Multiple adjustment modes can be set |
Simultaneous regulation: when simultaneous regulation is set, AD simultaneously collects the true effective values of three-phase voltages a, B and C for average calculation, and gives instructions for compensation, which can effectively improve the imbalance of three-phase voltage |
| Individual regulation: when individual regulation is set, the three-phase voltages are adjusted respectively to ensure that the three-phase voltages are within the accuracy range, especially suitable for single-phase load |
| Automatic judgment: microcomputer automatic analysis should carry out simultaneous or individual regulation. |
| Advanced measurement technology |
12Bit AD acquisition, digital filtering and true RMS calculation by single chip microcomputer |
| Accurate control |
Perfect cooperation between large-scale programmable logic device and single chip microcomputer |
