| The Acuvim series Intelligent Power Meter are an ideal choice when
continuous monitoring of a power system is required.
Programmable setpoints and two assignable outputs allow control
functions to be added for specific applications. This includes basic
alarm on over/under current, voltage, power, power factor, frequency,
unbalance factor or demand and pulse output based on Energy or
Reactive Energy. Status monitoring is possible using the 4 switch inputs.
It combines high accuracy measurement with intelligent multi-function
and simple HMI interface.
The Acuvim 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.
Power quality is important with increasing use of
electronic loads such as computers, ballasts or variable frequency
drives. Any phase current or voltage can be displayed and harmonic content calculated by
knowing the harmonic distribution. Action can be taken to prevent
overheated transformers, motors, capacitors, neutral wires and
annoying breaker trips. |
