DESCRIPTION

Acuvim II Advanced Power & Energy Meter Datasheet

FEATURES

+ Revenue Grade: ANSI C12.20 class 0.1 & IEC 62053-22 class 0.1s.

+ 4th CT input to measure neutral current.

+ Dual Ethernet ports with both RSTP bridge daisy-chain mode and separately configurable network.

+ High-resolution frequency measurement utilizes a custom moving average filter with 0.001Hz and 10mHz accuracy. Window size ranges from 1 - 50 cycles, and update rate varies from 1 - 2 cycles.

+ Data logging available with 8MB onboard memory and expandable to 8GB with WEB2 module.

+ IEC 61000-4-30 Class S compliant power quality event measurements for Acuvim IIW.

+ High-speed update rate.

Fast Read mode offers a 20ms Modbus refresh rate, Fast Log is available at 100ms and 50ms intervals via Modbus RTU and TCP/IP.

+ Compatible with multiple CT output options including 5A mA, Accuenergy Rogowski coil, or 333mV.

+ Modbus-RTU & BACnet MS/ TP ready. Optional modules add support for multiple industrial protocols & interfaces such as Modbus- TCP/IP, BACnet-IP, IEC 61850 2nd Ed., Wi-Fi, & EtherNet/IP.

The Acuvim II Series advanced power and energy meter is a robust solution for power monitoring, kWh metering, power quality analysis, and more. This multifunction meter is engineered for easy integration into any project environment and is compatible with a wide array of plug-in expansion modules to facilitate communication on over 15 different industry-standard protocols.

Its two available form factors include a panel mount meter with a digital display and a DIN rail transducer configuration.

With IEC 61000-4-30 Class S compliant power quality analysis, Acuvim IIW can monitor key PQ events such as harmonics, voltage swells and more.

KEY FEATURES

Communication

+ Modbus RTU protocol and BACnet MS/TP via RS485 + Wi-Fi and Ethernet Communication Channels (Modbus TCP, BACnet IP, HTTP, SMTP, SNTP, HTTPs, Post, FTP)

+ PROFIBUS DP

+ Dual RJ45 ports with RSTP daisy-chain and two individually configurable Ethernet ports

Data Logging

+ Acuvim II meters offer three assignable historical logs and a real-time clock to record many metering parameters with accurate timestamping. Add the AXM WEB2 module to expand the memory to 8GB with an adjustable log size.

+ WEB2 module offers additional granularity to data logging such as 1 second interval timing and max/ min/average and instantaneous reading for real time parameters.

Fast Response

+ 512 samples per cycle for measurement, 100ms and 20ms Modbus refresh rate, and 100ms and 50ms options Fast Logging for real time parameters including Frequency and Active Power.

Flexible Current Transformer Options

+ The Acuvim II is directly compatible with Rogowski coils plus a variety of other current transformer outputs, including 5A, 1A, 80mA, 100mA, 200mA, and 333mV. All CTs are available from Accuenergy.

Power Quality Measurements

+ Acuvim IIW offers IEC 61000-4-30 Class S compliant power quality event measurements. It is designed for monitoring and diagnosing power quality issues to improve efficiency and reliability, and enhance overall system performance. Perfect for energy management systems, building automation systems, and more.

Time of Use

+ Users can assign up to four tariffs (sharp, peak, valley, & normal) to different time periods within a day. The Acuvim II meter will calculate and accumulate energy to different tariffs according to the meter’s internal clock and TOU settings.

Optional I/O Module

+ Expand Acuvim II I/O functionality by connecting an optional I/O module. A maximum of three modules can be used per meter. Digital input, digital output, pulse output, relay output, analog input, and analogue output I/O modules are available.

Alarms

+ Limits can be set for up to 16 indicated parameters with a specified time interval. Parameters that are over or under the setting limit and persist longer than the specified time interval will be recorded and trigger the Alarm DO. Choose from 80 available parameters.

ACCESSORIES

DIN Rail Adapter

The AXM-DIN Rail Adapter is the easy way to mount the Acuvim II Series energy meter on either horizontal or vertical DIN rail. The adapter quickly secures to the meter and is compatible with all AXM communication modules as well as I/O options.

Protective Display Cover

The Protective Display Cover is designed for Acuvim II Series energy meters and other 96mm by 96mm display panel meters. Crucial in harsh environments, it increases the IP environmental rating of the meter's display to IP66 or NEMA 4X.

USB RS485 Converter

This plug-and-play USB to Serial RS485 Converter is designed to provide a convenient, reliable USB connection to the Acuvim II Series power meters and other serial devices.

ORDERING INFORMATION

Note:

Note:

1. Refer to the Communication table and I/O Module table.

2. A maximum of 3 modules may be attached to the meter. If a communication module is used (e.g. AXM-WEB2), it must be installed on the back FIRST before the other I/O modules are attached.

3. No more than 2 of the same I/O modules may be attached to the meter (e.g. two AXM-IO2). The same two I/O modules must have different logic numbers.

Logic numbers can be configured as either 1 or 2 through Acuview 2 or AXM-WEB2.

4. If Acuvim IIW uses DI to trigger a waveform capture, the I/O module logic number must be Module 1.

1. Accuenergy suggests using a USB-RS485 converter for configuration, and 3 CTs per three phase circuits.

2. All fields must be completed to create a part number.

3. Add “-S” after power supply for anti-tampering seal option.
