About the Acuvim-BL

Designed for facilities professionals that need a cost-effective and simple single/three phase kWh meter with pulse output. Also includes an on-board LCD display that shows most common electrical and power metering parameters.

The Acuvim-BL includes a digital pulse output for kWh or kvarh. Pulse rate and width can be set. Also comes with an Alarm output (no RS-485 Modbus®).

The Acuvim-L Series

The Acuvim-L series are multifunction power meters manufactured by Accuenergy. It is the ideal choice for monitoring and controlling of power distribution system.

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 Modbus® Protocol (excluding Acuvim AL and BL models).

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.

Alarms

Two (2) parameters 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.

Communication

RS485, industry standard Modbus® RTU protocol; (Only on models CL/DL/EL/KL)
Option the second RS485, Modbus® RTU protocol; or PROFIBUS-DP/V0 (available for the DL/EL Models)
Protocol. (just for Acuvim-DL/EL)

Display

Clear and large character LCD Screen display with white back light; Wide environmental temperature endurance.

Applications

• Metering of distribution feeders, transformers, generators, capacitor banks and motors.
• Medium and low voltage systems.
• Commercial, industrial, utility.
• Power quality analysis.
