Din-Rail Energy Meter (DRT301)

Product Description

General Descripition
DRT series three phases DIN RAIL kWh meter adopts International technology of surface decoration with high-precision electric elements. It has the functions of high accuracy, stability, small size, light weight, low power consumption and bilateral recording with indication of missing phase, sign of output pulse so that it is easy for extended functions of modernized management. It conforms to the related GB/T17215-2002 and IEC62053-21.

Technical Specification
1 Measuring the active energy of three phase consumption correctly. In case of reverse energy connection;
2 With high performance characteristics of measurement (with flat typical load curves), long working time without readjustment
3 Power supply by three phases, the accuracy of the measurement is not affected by power cut in one or two phases.
4 Indications of phase break or voltage.
5 Two Display Modes:
A Mechanical register driven by stepper motor. (counter6+1=999999.9)
The motor is specially designed with shield for high anti-interfere feature.
B LCD 6+1=999999.9/5+2=99999.99 kWh
6 Low power consumption, less than 1.2W for meter.
7 Wide voltage rage applicable, 0.8Un~1.2Un
8 27 choices of the CT Ratio of watt-hour meters with CT. Measure the original power.
9 35mm standard DIN rail installation, Impulse output, complying with standard DIN43864.
10 The EMC feature complies with IEC62053-21
11 May select infrared communication interface and RS485 communication interface.
