Product Description Technical consultant Susan 1 Product descriptionMQ21, the power quality analyzer externally connected with open type Rogowski coil or voltage CT, it can realize no dismantling wire test, facilitate engineering test, simplify test steps, save construction cost, and is also more convenient for the inspection and maintenance of distribution system. MQ21 supports systems of single-phase and three-phase: it can measure multiple electrical parameters such as voltage, current, harmonic, energy, power factor and active power on the power grid of phase A, B, C and phase N. With standard configuration of RJ45 and RS485 communication interfaces, through standard Modbus TCP and Modbus RTU protocols, it can be compatible with various configuration systems and transmit the electrical parameters collected by the front end to the system data center in real time.

The power supply voltage range: 90~528VAC, 45~60Hz, Mam power consumption 2.5W.Do not connect the analyzer when the cable is live;Before connecting the power supply, be sure to confirm whether the power supply voltage is within the required range, otherwise the analyzer cannot work normally.5.2 Voltage current inputThe analyzer supports 5 wiring modes: 3ф_WYE_4CT, 3ф_WYE_3CT, 3ф_DELTA_3CT, 3ф_DELTA_2CT, Single phase. The actual wiring mode of the analyzer must be consistent with the one configured inside the analyzer.3ф_WYE_4CT need 4pcs current sensor, and N-phase current can be measured.3ф_WYE_3CT need 3pcs current sensor, N-phase current cannot be measured.3ф_DELTA_3CT need 3pcs current sensor, phase B current is acquired by sensor actual measurement.3ф_DELTA_2CT need 2pcs current sensor, phase B current is acquired by calculating.The phase sequence of voltage and current must correspond one by one, otherwise the measured data of the analyzer is incorrect.When using the current sensor, note that the direction of the current arrow on the sensor must be consistent with the actual current flow, that is, the sensor current arrow points to the load end.
