MQ21-4G Edge Processing Gateway
MQ21-4G Edge Processing Gateway
Product Description:
MQ21 supports both single-phase and three-phase systems.
It measures various electrical parameters, including voltage, current, harmonic, energy, power factor, and active power on phase A, B, C, and N of the power grid. It features RJ45 and RS485 communication interfaces with Modbus TCP and Modbus RTU protocols for compatibility with different systems.
The device supports multiple types of current sensors, such as Rogowski coils and voltage-output current clamps.
It has a 1.3-inch color OLED display screen and weighs approximately 400g.
The MQ21 has various input current and voltage ranges, as well as overload capacity specifications.
It can be powered from the main electrical loop or an external 18650 lithium battery.
The maximum power consumption of the device is 2.5W.
Functionality:
Measurement capabilities include voltage, current, power (active, reactive, apparent), energy, line voltage, angle between line voltages, angle between currents, power factor (including harmonic and fundamental), and more.
It can record data with customizable intervals and store it in CSV format on a 16GB micro SD card.
The device can measure and record power quality parameters such as voltage swell, voltage dip, voltage harmonic values, current harmonic values, and more. It can also record event data in CSV format.
Accuracy and Certification:
Measurement accuracy for current using Rogowski coils ranges from 0.5% to 1% (1% to 120% rated current) with specific current gear

MQ-21 Power Quality Analyser & Event Recorder.
DIN Rail Mounting
MQ-21 Power Quality Analyser & Event Recorder. DIN Rail Mounting
Application
Power Quality Analysis and Consumption. Solar Grid-Connected PV Generation System, Consumption, Event Recorder and Multifunction Fault Recorder.
Event Recording
Acts as an Event recorder to log Dips, Surges and other events. Event recordings include Event type, Start time, Duration, Amplitude, Voltage RMS half value and Voltage waveform.
Features
Supports systems of single-phase and three-phase.
Measures multiple electrical parameters voltage, current, harmonic, energy, power factor and active power on the power grid of phase A, B, C and phase N.
Equipment Temperature
Note that even the equipment temperature can be monitored via three thermocouple inputs (MQ-21 Pro).
Auxiliary supply
MQ21 requires power which can be obtained from the major loop between 90 and 526 volts AC, or from an optional external Lithium 18650 battery set charged from 230Vac.
Communication
Standard communication configurations such as of RJ45 and RS485 interfaces.
Standard Modbus TCP and Modbus RTU protocols.
MQ21 is compatible with various configuration systems and transmits the electrical parameters collected by the front end to a selected point in real time via Modbus.
Data can be stored onto a 16 G Micro SD card and downloaded by USB.
Optional: It can also be connected to the internet via optional MQ-21-4G Gateway.
Connections
Two models are offered:
1. Type C which uses Standard CT s.
2. Type R which uses open ended Rogowski clip on coils (available in 3 sizes: 600Amp. 3000Amp and 6000Amp). These clip coils are very accurate (0.5% full scale) and extremely convenient as there is no disconnection of the main power supply, and often there is no need to do plant shut-downs.
