CNDTS309 electronic three-phase four-wire active energy meter (with RS485 interface)
Scope of application
DTS309 electronic three-phase four-wire active energy meter is electronic 1.0 and 2.0 active energy meter, used to measure the reference frequency 50HZ AC circuit in the three-phase active energy, all in line with national standards GB / T17215.321-2008, It is characterized by:
1, two-way metering accurate measurement of the power of positive and negative direction, long-term work does not need to adjust, and in a direction cumulative power, and a tampering function.
2, three-phase power supply, one phase or two-phase power, measurement accuracy is not affected;
3, the use of optical isolation technology output pulse signal energy, light-emitting diodes indicate electricity, with the lack of phase display function.
