A1700 Meter

The A1700 meter provides the complete solution for complex time of use metering for commercial and industrial consumers. The following versions of the meter are available:

  • Direct Connected meter
  • CT or CT-VT operated meter
  • Multi-utility compatible meter providing data collection from external meters
  • Class 0.2s, CT-VT multi-utility transformer loss compensation meters


The A1700 is of modular design, allowing one module for input or output and one module for communications to be fitted underneath the terminal cover.

The A1700 incorporates 4 levels of security passwords. Passwords can be disabled if required.

The Meter can be programmed or read either locally or remotely. Local communications is established via an optical communications port, using a PC or Hand Held Unit incorporating the IEC 62056-21 (formerly IEC 61107) protocol. 

A Communications Module (RS232 or RS485) provides for remote communications either directly from a PC or via a modem e.g. PSTN, GSM, GPRS, Eternet etc.
The A1700 meter is housed in a polycarbonate polyphase meter case, which allows safe access to the auxiliary terminals.

Elster Metering Systems Power Master Unit Software provides a WindowsTM based platform for ease of programming the A1700 and reading meter data.
