DDSD666 Single Phase Multifunction Meter
DDSD666 Single Phase Multifunction Meter is used in one phase two wire power network. It can be integrated into AMI system and it complies with IEC and EN standard and uses DLMS/COSEM protocol to communicate with the utility by local communication (RS485 and Optical port) and remote communication modem for energy consumption monitoring/power net quality monitoring/event record monitoring.
◆ DLMS/COSEM protocol ensures an open and secure communicational system and well compatibility performance.
◆ Supporting multi remote communication modem, for example: GPRS/3G/4G/PRIME-PLC/ G3-PLC/ Mesh RF/Ethernet, Easy to replace on site and register automatically.
◆ Unidirectional or Bi-directional energy measurement, including active forward and reverse active energy measurement, Instantaneous value measurement.
◆ Combinational reactive energy and four quadrant reactive energy, apparent energy.
◆ Multi-tariff with 10 switch-time tables, 8 day tables, 12 week tables and 12 season tables.
◆ Maximum demand for total and tariffs active/reactive/apparent power.
◆ At least 6 channel load profile records.
◆ Event log function including multiple tamper event detections/power off event detections /load control detections.
◆ Flexible RTC with accuracy 0.5s /day, and leap year auto switch.
◆ Easy to identify the alarm and error via the LCD display and LED.
◆ Easy to operate by 2 buttons.
◆ Standard BS or DIN bottom convenient for site installation.
◆ Easy to replace the Battery in the field.
◆ LCD backlight can increase readability under low light condition.
