Function Summarization

It can measure the single-phase/three-phase active/reactive power value of electric circuit and display in figure direct reading way. It supports the signal input ways of single-phase, three-phase three-wire, three-phase four-wire. There is programmable keyboard on the panel. It can set the multiplying power of the mutual inductor.

Model & Specification & Selection Table

Basic Parameter

★Rated input voltage: AC 100V, 220V, 380V (multiplying power of the mutual inductor can be set freely) 
★Rated input current: AC 1A, 5A (multiplying power of the mutual inductor can be set freely) 
★Measure and display range: 0~999W~999kW~9999MW (unit can be switched automatically) or 0~999var~999kvar~9999Mvar (unit can be switched automatically) 
★Accuracy of measurement: ±0.5% range ±1 character (active power); ±1% range ±1 character (reactive power)
★Resolving ability: maximum is 1W (or 1 var), decimal point will shift automatically
★Measuring rate: about 3 times / s
★Power consumption of input loop: <0.5VA
★Polarity indication: it can display the reverse power, negative signal will automatically display ” -”
★Auxiliary power supply: AC 220V ± 10%
★Power consumption of auxiliary power supply: <3VA
★Working environment: temperature is -10~+50°C,humidity<85% RH,without any corrosive gas
★Safety withstand voltage: using the AC 2kV withstand voltage test to measure between the input terminal and the power supply terminal
