Discontinued!
This product has been discontinued and is no longer available.
This is the direct replacement:
The Acuvim IIE is an intelligent multifunction power meter that is TOU enabled for single and three phase circuits. The Acuvim IIE 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.
Users of the Acuvim IIE can assign up to 4 different tariffs (sharp, peak, valley and normal) to different time periods within a day according
to the billing requirements. The Acuvim IIE meter will calculate and accumulate energy to different tariffs according to the meter's internal clock timing and TOU settings. The TOU feature allows you to configure up to 4 tariffs, 12 seasons and 14 schedules.
Since the Acuvim IIE features 0.2% accuracy and meets the ANSI C12.20 standard for revenue grade meters so it can also be used for tenant sub-metering applications.
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 a Revenue Grade Power Meter should look at the Acuvim-IIR instead.
Metering
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 IIE 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.
