Acuvim-L Series
Multifunction Power Meter



The Acuvim-L series are multifunction power meters manufactured by Accuenergy. It is the ideal choice for monitoring and controlling of power distribution system. Some of the features and electric power parameters available on the ultra-compact Acuvim-L are:

  • True-RMS measuring parameter
  • 4-quadrant Energy
  • Power Quality Analysis
  • Over limit alarm
  • Energy pulse output
  • TOU, 4 Tariffs, 12 Seasons, 14 Schedules

Acuvim-L may be used as a data gathering device for an intelligent Power Distribution System or a Plant Automation System. All monitoring data is available via digital RS485 communication port running ModbusTM Protocol.

The quality of the power system is important with increasing use of electronic loads such as computers, ballasts or variable frequency drives. With the Acuvim-L power analysis option, any phase current or voltage can be displayed and the harmonic content calculated. By knowing the harmonic distribution, action can be taken to prevent overheated transformers, motors, capacitors, neutral wires and nuisance breaker trips. Redistribution of the system loading can also be determined.

One (1) alarm parameter may be set within a specified time interval. If indicated parameter 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 indicated parameter can be selected from any of the 35 parameters available.

Pulse Output option
Two Digital outputs can be configured as pulse output for kWh and kVarh. The pulse rate and width can be set.

RS485, Industry standard ModbusTM RTU protocol
