Prepayment Intelligent Electric Meter , Single Phase Watt Hour
Meter High Accuracy
DDZY150 single phase smart prepayment meter is the smart
measurement and load control unit which can be used in one phase
two wire power network. It can be integrated into AMI vending
system and it complies with IECENSTS standard and uses DLMS/COSEM
and STS 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/load limited monitoring/event record monitoring/credit
- DLMS/COSEM HDLC and IPV4 protocol ensures an open and secure
communicational system and well compatibility performance.
- STS standard protocol ensures an open and secure prepayment vending
system, the numeric token is transferred into the meter via local
and remote communication.
- Prepayment and postpaid mode switchable according to customers’
- 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
- Combinational reactive energy and four quadrant reactive 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
- Internal switch relay for load control by configuring, load limited
control and at least 6 channel load profile records.
- Event log function including multiple tamper event detections/power
net 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 and 3x4 number function keypad.
- Standard BS or DIN bottom convenient for site installation.
- Easy to replace the Battery, without uninstalling.
