Gomelong is a professional manufactures of Three Phase Multifunction Digital Power Meter.Our professional expertise in manufacturing Three Phase Multifunction Digital Power Meter has been honed over the past 10+ years. Three Phase Multifunction Digital Power Meter is able to measure various electricity parameters with high accuracy, such as three phase voltage , three phase current, three phase combined voltaqet and three phase active power etc. They can measure the switching Value in four circuits (capable of telesignalization) and have the function of relay output in two circuits (capable of telesignalization).
Application of Three Phase Multifunction Digital Power Meter
√Three phase multifunction digital power 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 multifunction digital power meter of series X measure and display electrical parameters such as current, voltage, power, frequency and power factor etc. It can display the parameters directly and accuracy. It is anti-vibration, of high accuracy and stability and able to measure effective AC value. It can also be used in serious harmonic distortion. Current ratio can be displayed by pressing the keys.
√Based on series X, three phase multifunction digital power meter of series K add 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 multifunction digital power meter, programable alarm meters are designed for electricity systems and industrial mining enterprises demanding current control and detection. They are able to 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. They can measure the switching Value in four circuits (capable of telesignalization) and have the function of relay output in two circuits (capable of telesignalization). Three phase multifunction digital power meter can also 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
