Description Features: This module is mainly used for the measurement of AC voltage, current, active power, frequency, power factor and active energy. This module has no display function, and the data is read through a specific interface. We provide software to connect it to a computer If you want to connect with other terminal devices, prepare the appropriate cable and write your own program. Notice: Objects may have Logo, if you want to know, please contact us. Otherwise, please do not bid. Specification: Voltage Measurement range: 80-260V Resolution: 0.1V Measurement accuracy: 0.5% Current Measuring range: 0-10A Initial measurement current: 0.01A Resolution: 0.001A Measurement accuracy: 0.5% Active power Measuring range: 0-23kW Initial measurement power: 0.4W Resolution: 0.1W Display format: When the data is less than 1000W, one digit after the decimal point is displayed, for example: 999.9W When the data is greater than 1000W, only integers are displayed, for example: 1000W Measurement accuracy: 0.5% Power factor Measurement range: 0.00-1.00 Resolution: 0.01 Measurement accuracy: 1% Frequency Measurement range: 45Hz-65Hz Resolution: 0.1Hz Measurement accuracy: 0.5% Active Energy Measuring range: 0-9999.99kWh Resolution: 1Wh Measurement accuracy: 0.5% Display format: When the data is less than 10kWh, the display unit is Wh, for example: 9999Wh When the data is 10kWh, the display unit is kWh, for example: 9999.99kWh Reset energy: Use software reset.
