About the Acuvim-CL

A highly capable but lower cost series of multi-functional single/three phase MODBUS RS485 power meters that measures most common electrical parameters. Available with LCD display or DIN Rail mount transducer (no display). All versions include MODBUS RS485 output.

The Acuvim-CL includes a digital pulse output for kWh or kvarh. Pulse rate and width can be set. Also comes with an Alarm output. Communications through MODBUS RTU via a built-in RS485 serial port.

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.

Those looking for Time of Use (TOU) features should look at the Acuvim-EL instead.
