DDS38 Measuring AC single-phase bi-directional Ene

energy meter,electric energy meter,electronic energy meter energy meter: GENERAL The DDS38 single phase electronic meter is designed for measurement of electric energy flowing in one or two directions in households and at commercial customers in single phase 2 wire networks. It complies with IEC61036 standard and is manufactured in compliance with the ISO9001 standard. METERING SYSTEM The meter is composes of several parts including input sensors, the high quality measuring IC, the register and the indicators. The metering element is shielded against external magnetic fields and is protected against over voltages and high frequency disturbance. energy meter Register energy meterThe meter is equipped with one 6-digit register. The figure size is 5×3mm. The decimal drum can be coded or covered on request and has 100-division marking on its circumference. The register is driven with a step motor that is shielded against external magnetic fields. MAIN FEATURES Measuring AC single-p hase bi-directional energy.Anti tamper.Wide measurement range, low power consumption and high reliability.Small volume, light weight and good appearance. ANTI TAMPER FEATURES Theenergy meter can record energy correctly at the following common ways of tamper: 1) The input and output terminals are interchanged. 2) The phase and neutral are interchanged at the input terminal. 3) The influence of external D.C/A.C magnetic field of high intensity.
