Our professional expertise in manufacturing Three phase current voltage frequency meter has been honed over the past 10+ years. Three phase current voltage frequency meter supports RS-485 communication, Modbus-RTU protocol.Provide the digital tube display, local data query.Three phase current voltage frequency meter has a variety of shapes, to meet the different requirements of the cabinet body electric circuit.
Application of Three Phase Current Voltage Frequency Meter
√Three phase current voltage frequency meter is used in power grid and automatic control system measuring various electrica parameters such as current, voltage frequencv, power factor, active power and reactive power etc. Based on the additional functions, we divide digital meters in four series: X, K, D, S
√Three phase current voltage frequency meter of series X measure and display electrical parameters such as current, voltage, power, frequency and power factor etc. Can display the parameters directly and accuracy. Three phase current voltage frequency meter is anti-vibration, of high accuracy and stability and able to measure effective AC value. Also can be used in serious harmonic distortion. Current ratio can be displayed by pressing the keys.
√Based on series X, three phase current voltage frequency meter of series K adds three analog quantity transmitting output(4-20mA). Users car hoose to add RS485 communication interface output(Modbus-RTU protocol). Meters can digitally display in three rows as well as to be switched to display in single row.
√Series S of three phase current voltage frequency meter , programable alarm meters are designed for electricity systems and industrial mining enterprises demanding current control and detection. Measure various electricity parameters with high accuracy, such as three phase voltage , three phase current, three phase combined voltaqe¤t and three phase active power etc. Three phase current voltage frequency meter can measure the switching Value in four circuits (capable of telesignalization) and have the function of relay output in two circuits (capable of telesignalization). Achieve telesignalization function by RS-485 port using Modbus-RTU Protocol. Parameters of transformer ratio can be set by pressing the keys on the meter panel
Product Description of Three Phase Current Voltage Frequency Meter
Three phase current voltage frequency meter can accurately measure and display all the common electrical parameters of three phase power grid, such as three phase voltage and current, active power, inactive power, power factor, frequency, active energy, reactive energy, communication interface and energy pulse output function. With MODBUS-BTU communication protocol, the meters can display by LCD and achieve RS-485 remote digital communication. With features of convenient installation, easy wiring and maintenance, programable at site etc. Three phase current voltage frequency meter can also proceed the networking communication between different PLC and industrial control computers among the industry.
