Alarms
- 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 31 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.
Display
- Clear and large character LCD Screen display with orange back light

| 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. |
