3 Phase Din Rail Energy Meter DTSU2788-7P

Introduction:

• Our 3 Phase Din Rail Energy Meter DTSU2788 and DSSU2788 both adopt microelectronics technology and are used to measure the active electrical energy of three-phase AC with a rated frequency of 50/60HZ.
• They measure the electricity consumption in both forward and reverse directions equally. There are two connection methods for this series of electronic three-phase watt-hour meters: direct connection type or connection via mutual inductor type.
• This 3 Phase Din Rail Energy Meter all the technical requirements for din-rail three-phase electric energy meters specified in the national standard GB/T17215.321-2008 《Class 1 and Class 2 Static AC Active Watt-Hour Meters》
• Measures three – phase active electrical energy, no need for calibration during long – term operation.
• Powered by three – phase power supply. If one wire (any one of the three wires of a three – phase three – wire electric energy meter) or two wires (any two of the four wires of a three – phase four – wire electric energy meter) is disconnected, the measurement accuracy is not affected.
• Wide operating temperature range.
• Has phase – failure indication function or voltage indication function
• Display methods: counter, liquid crystal.
• Has remote power – off function.
• Output interface: RS485.
