These revenue grade meters feature data logging capabilities, True-RMS parameter measurement, digital RS485 communication port, and are compatible with different current transformers.
The Acuvim IIR is a revenue grade multifunction power meter with data logging capabilities for single and three phase circuits. The Acuvim IIR meter features Modbus RS485 communication standard and can be upgraded to include Modbus TCP Ethernet, BACnet, Profibus, and a variety of other communication protocols and I/O expansions for added versatility.
The Acuvim IIR features 0.2% accuracy with ANSI C12.20 standard for revenue grade meters and maintains a historical record of data for users to remotely monitor trends, analysis and reports with the capability to set threshold alarms in such applications as tenant and facility metering. Acuvim IIR offers 3 assignable historical logs where the majority of the metering parameters can be recorded. The onboard memory is up to 8 MB and each log size is adjustable. A real time clock allows for any logged events to be accurately time stamped. With AXM-WEB2, memory size expands to industry-leading 8GB memory with 1-second interval data logging.
The Acuvim II series are high-end multifunction power and energy meters
manufactured by Accuenergy. They are the ideal choice for the monitoring
and controlling of power distribution systems.
The Acuvim II series may be used as data gathering devices for
intelligent power distribution systems or plant automation systems.
All monitored data is available via a digital RS485 communication
port running Modbus RTU protocol. Ethernet and Profibus DP
communication are also options.
With its flexible, modular I/O and communication options, the Acuvim II
series is the most versatile and cost-effective metering solution on the
market.
Those looking for Time of Use (TOU) features should check out the Acuvim-IIE instead.

Monitoring
Alarms
Limits can be set for up to 16 indicated parameters and can be set with
a specified time interval. If any input of the indicated parameters is over
or under its setting limit and persists over the specified time interval,
the event will be recorded with time stamps and trigger the Alarm DO
output. The 16 indicated parameters can be selected from any of the 51
parameters available.
Data Logging
Acuvim IIR offers 3 assignable historical logs where the majority
of the metering parameters can be recorded. The onboard memory is up to 8 MB and each log size is adjustable. A real time clock allows for any logged events to be accurately time stamped.
The Acuvim II Series is available in two mounting options:
The standard model is ANSI C39.1 Standard Compliant with a small size 96x96 outline.
The DIN Rail compatible units are DIN 43700 Standard Compliant. The Acuvim II series also offers an optional Remote LCD display.
