MITSUBISHI ELECTRIC 三菱电机 MELSEC-Q 功率计

"QE81-WH is a powerful tool that can be used as part of any serious attempt at energy saving by measuring different energy-using circuits and tracking and consumption variables; Line Current, Line Voltage, kW, kVAr and Power factor can all be tracked in real time. Data generated by the module can easily be transmitted to other equipment over any suitable network type, for example EtherNet, and stored and displayed or imported into energy monitoring software, such as ICONICS Energy Analytics. In addition to the obvious energy saving applications, measuring energy use can also be very valuable in spotting problems in a manufacturing process; for example, a sudden rise or fall in power consumption could mean the start of a mechanical problem in a machine such as a bearing or alignment problem or a broken belt, and allow preventative maintenance to take place at an early stage. Main Features of QE81-WH • Simple connection to existing circuits using Snap-On current transformers • Fast and accurate measurements updated at 250msec intervals • Simple connectivity with related Mitsubishi products via. The Q series back plane, for example GOT display screens. • Measurement upper \/ lower limit levels can be set, allowing for alarms if there are unexpected deviations in."
