Acuvim II Series
Intelligent Power Meter (Web Accessible)


The Acuvim II is a high-end multifunction power meter manufactured by Accuenergy. It is the ideal choice for monitoring and controlling of power distribution systems. Some of the features and electric power parameters available on the ultra-compact Acuvim II are:

  • True-RMS Measuring Parameter
  • ANSI C12.20(0.2 Class) and IEC 62053-22(0.2S Class)
  • Power Quality Analysis
  • Over Limit Alarm
  • Multi Communication Ports (Eg: Ethernet, Modbus)
  • Web Server and Email Sending
  • Switch Status Monitoring
  • Remote Switch Controlling
  • Measure Individual Harmonics from 2nd to 63rd(Acuvim IIR)
  • Module Design
  • Data-Logging

Acuvim II may be used as a data gathering device for an intelligent Power Distribution System or Plant Automation System. All monitored data is available via a digital RS485 communication port running Modbus-RTU Protocol. Ethernet and Profibus DP communication are also options and with new wireless technologies and protocols currently under development, the applications for the Acuvim II meter are limitless.

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.

I/O option module
The E-module® technique was adopted for its flexibility and easy expansion of the I/O function of Acuvim II. A maximum of 3 modules can be used for one meter. Digital input, digital output, pulse output, relay output, analog input and analog output are provided by I/O option module.

RS485, Industry standard Modbus™ protocol
Module Option: Ethernet module, Profbus-DP module
Dual communication ports

Clear and large character LCD Screen display with white back light
Wide environmental temperature endurance
Display Load percentage, 4 quadrants power and load nature

Small Size 96×96 DIN or 4’’ ANSI Round

Data_logging New
The Acuvim IIR model offers 4MB of onboard data logging memory to be used for historical trending. There are 3 assignable historical logs where the majority of the metering parameters can be recorded. A real time clock allows for any logged events to be accurately time stamped.
