Product Range

DDS7171 Single-Phase Meter

DDS7171 adopts a dedicated measurement LSI and a simplified electronic structure for high reliability, low power consumption and long service life. It is suitable for single-phase AC active energy measurement and conforms to GB/T17215-2002 class 1 and class 2 static AC active watt-hour meter requirements.

• Measures active electric energy without long-term calibration.
• Uses ADE7755 special measurement chip.
• Wide dynamic working range with overload capability over 10 times.
• Good error linearity in the range of 5% Ib to Imax.
• Low component count, low power consumption and long-life electronic components.

DTS7171 Three-Phase Meter

DTS7171 uses microelectronic technology to measure active electric energy in three-phase AC systems. It supports direct connection and mutual-inductance connection modes, and conforms to GB/T17215-2002 class 1 and class 2 static AC active watt-hour meter requirements.

• Measures three-phase active electric energy without long-term calibration.
• Three-phase power supply design keeps measurement active when one or two phases are missing.
• Wide service temperature range.
• Defect phase indication or voltage indication function.
• Display options include register, LCD and digital tube.
• Remote power supply interruption function and RS485 output interface.
