Acuvim II 5A (DIN Mount - No Display)
Model- Acuvim II Series
(UL, cUL, and CE Certified)

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

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.
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.
Communication
RS485, Industry standard Modbus protocol. Module Option: Ethernet module, Profbus-DP module. Dual RS485 communication ports.
Display
Clear and large character LCD Screen display with white back light. Wide environmental temperature endurance. Display Load percentage, 4 quadrants power and load nature.
Outline
Small Size 96X96 DIN or 4" ANSI Round.
Data_logging
The Acuvim IIR, Acuvim IIE, 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.
Time of use
User 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 meter will calculate and accumulate energy to different tariffs according to the meters internal clock timing and TOU settings.
