Three Phase Four Wire Smart Energy Meter
Type: DTSD1311
This energy meter supports bidirectional active energy measurement and multiple instantaneous electrical parameter measurement. Its multi-tariff function can be effectively activated via internal settings, and power consumption can be tracked by means of load profile records. Apart from regular event logs, it records tampering events such as meter cover opening and magnetic interference. Near-infrared local communication is also available. Meter parameters can be freely configured through PC software with high flexibility.
