9330/9350 Advanced Power Meters
Features and Benefits
Advanced Power Meters
Used in diverse applications from
metering equipment and buildings,
through monitoring the status of
feeders and key interchange points,
the 9330/9350 series offers unmatched
value, functionality, and ease of use.
The 9330 offers hundreds of
3-phase power, energy, demand,
and harmonics measurements, digital
outputs, an optional Ethernet port,
Internet connectivity and many
space-saving configurations.
The 9330 meter also provides on-board
data on-board data storage, setpoints,
digital I/O, an optional Ethernet port
and optional built-in modem, either of
which can be used as a gateway to as
many as 31 serial devices.
The 9350 meter is further augmented
by a sampling rate of 64 sample/cycle,
waveform recording, sag/swell,
enhanced harmonics and a call-back
function for prompt response to
critical alarms.
Integrate any of the 9300 Series
products with our WinPM.Net™
software or other automation systems
for information-sharing among many
departments and user groups.
Patented technology lets you customize
metering or analysis functions at your
workstation, without any hard-wiring.
Just graphically link a few drag-and-drop
icons, or select default setups, and
you're ready to go.
Not all features listed are available with every
model. Please refer to the detailed descriptions
within for a complete list of feature availability.
Applications Summary
Power and Energy Metering
Each meter in the versatile 9300
series gives you hundreds of high-
accuracy power, energy, demand
and harmonics measurements. Use
the revenue-certified models for
billing, bill verification, and sub-
metering applications.
Power Quality Analysis
Discover the sources of harmonics and
voltage sags/swells. Analyze problems
and avoid repeat interruptions.
Cost Allocation and Billing
Determine cost centers, identify
opportunities for demand control and
check energy consumption patterns.
Demand and Power Factor Control
Avoid penalties with automated load
shedding, scheduling, peak shaving
or capacitor bank control.
Load Studies and Circuit Optimization
Determine the capacity of your electric
network and run at peak efficiency.
Perform load trending.
Equipment Monitoring and Control
Improve process yields and extend
equipment life. Meter all your utilities
including gas, steam, water and more.
Preventative Maintenance
Set up alarms to warn of pending
problems. Log events and alarms for
all critical conditions.
