Description

Technical Specification

● .Measuring the active energy of three phase consumption correctly. In case of reverse energy connection;

● With high performance characteristics of measurement (with flat typical load curves) ,long working time without readjustment

● Power supply by three phases, the accuracy of the measurement is not affected by power cut in one or two phases.

● Indications of phase break or voltage.

● Two Display Modes:

A、Mechanical register driven by stepper motor。(counter6+1=999999.9)

B、 LCD（6+1=999999.9/5+2=99999.99 kWh）

● Low power consumption, less than 1.2W for meter.

● Wide voltage rage applicable,0.8Un～1.2Un

● 27 choices of the CT Ratio of watt-hour meters with CT. Measure the original power.
