Product Description:
The Acuvim-L series are the ideal choice for monitoring and controlling power distribution systems. Acuvim-L may be used to gather data from intelligent Power Distribution Systems . All Data can be accessed via 485 communication port running Modbus™ Protocol. Optional Ethernet, Profibus DP communication and wireless transmission add flexibility to all your application needs.The quality of your 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.
