A1120/40
The A1120/A1140 provides a comprehensive and secure tariff structure and security and is suitable for commercial and light industrial CT or direct connected applications. The A1140 offers additional load profiling.
Communications are provided via the optical (IEC 62056-21) port and are supported by data stream mode, allowing fast reading of meter data. The A1140 permits up to one channel of 90 days load profile data to be collected in less than 30 seconds. An RJ11 socket provides optional serial communications allowing remote access to the same meter data. This port can be multi-dropped, allowing up to 10 meters to be accessed from a single communications device. As a further option, a pulsed output can be transmitted via the meter’s auxiliary terminals.
The meter display has large characters that can be viewed from a wide angle.
Power Master Unit software provides a user friendly WindowsTM graphical interface for programming the meter and reading meter data.
