Modular Single Phase Smart Energy Meter Multi Communication Remote AMI Management

Product Type:
135A is modular-design direct-connect single-phase AMI smart prepaid meter.
Application:
Accurately measure electric energy for residential customers, complying with international energy meter standards.
Billing Mode:
Switchable prepaid / postpaid mode; prepaid function complies with STS standard.
Communication:

Plug-and-play replaceable modules: WIFI, RF, GPRS, 3G, 4G, NB-IoT, Wi-SUN, PLC for remote management.
Multi-protocol support: DLMS/COSEM, ANSI, DL645-2007, Modbus-RTU.

Detects: load unbalance, voltage missing, current bypass, phase reversal, neutral disturbance/cut, magnetic tamper, 35kV ESD disturbance, cover-open.
Maintains measurement accuracy, logs events and performs punitive measurement to protect utility assets and revenue.

Mode Selection:
Prepaid / postpaid can be selected via local tools (CMRI, HHU, CIU) or remote communication by utility company.

Please read this manual fully before installation, operation, testing and usage.
The meter can tolerate rough field handling. Proper care ensures long-term trouble-free operation.
Manufacturer shall not be liable for consequential damage caused by wrong application, misuse or incorrect installation.

Product nature: 135A is an all-electronic, solid-state single-phase energy meter.
Measurement capacity: Accurately measures supply voltage, current, power factor and other parameters; measures active, reactive and apparent energy as applicable.
Hardware core: Built around ASIC-based micro-controller with dedicated programming language.
Programmability: High programmability to support diverse applications and tariff schemes.

Adopt analog-to-digital converter to sample voltage and current of input waveform.
High sampling rate delivers outstanding measurement accuracy.
Available accuracy class: 1.0 class, 0.5S class.
