switching; It supports kWh pulse output.
System Event Logging
This product runs self-check on systems. When an important operation is performed (such
as reset, energy or demand clear, system parameter changes), it immdediately records
the event timestamp, event type (via event state word), and judges whether relay output
needs to be sent.
Over/Under Limit Alarming
Users can select parameters and set their setpoints.An alarm will be triggered when the
setpoint is reached.At the same time, sound and light signals could be sent out via relay
output. The time and reason of an alarm event will be recorded.
Power Quality Analysis
Power quality parameters such as voltage and current THD, Odd harmonic distortion (Total
Odd HD), even harmonic distortion (Total Even HD), 2 ~ 31 times the harmonic content,
Current K-factor (KF), crest factor (CF), telephone interference factor (THFF), voltage and
current unbalance etc. will be monitored.
I/O Option
Standard output ports provide energy (kWh) pulse output and time pulse output; digital
inputs (DI) provide pulse counting from water, electricity and gas meter, and monitor
switch status; relay outputs (RO) react upon alarming conditions.
Data Logging and Load Trending
With 8MB of onboard memory, AcuRev 2000 series can log real-time metering
parameters, I/O status, and energy measurement. This information can be used for
historical trending and system analysis.
