9330/9350 Advanced Power Meters
Features and Benefits
Metering
The 9300 series provide fully bi-directional,
4-quadrant, revenue accurate or revenue-
certified energy metering. They can
replace discrete energy meters, demand
meters and pulse initiators and perform
a wide range of other metering and
instrumentation functions.
4-Quadrant Energy
The units are fully bi-directional and
meter energy in all four quadrants.
They provide all traditional active,
reactive and apparent energy para-
meters and can provide measurements
like Volt-Hours, Amp-Hours, etc.

Integration of any instantaneous
measurement
Demand
The 9300 series support block,
sliding window (rolling interval),
thermal, and predicted demand.
The meters calculate demand on
any instantaneous measurement
and records peak (maximum) and
minimum demand. Peak demand
registers can be reset manually
(password protected) from the front
panel or via communications.
Default setup:
kW demand and min/max
kVAR demand and min/max
kVA demand and min/max
Amps demand and min/max
Volts demand and min/max
Demand on any instantaneous
measurement
Instantaneous
The 9300 series offer the most
comprehensive array of instantaneous
(real-time) measurements available in
the industry. Measurements include
true RMS, per phase and total for:
Voltage and current
kW, kVAR and kVA
Power factor
Frequency
Voltage and current unbalance
Time-of-Use
The 9330 and 9350 provide:
2 year internal calendar
Up to 15 daily tariff profiles
Programmable triggers
Separate energy and demand
accumulators
Harmonics
The 9300 series meters feature
harmonic distortion metering.
Total Harmonic Distortion and
individual harmonics up to the 15th
in the 9330 and to the 31st in the
9350 for voltage and current inputs
K-factor for current inputs
Universal Metering
The 9300 series meters can be equipped
with a variety of digital and analog I/O
combinations, for universal metering.
You can replace PLCs and RTUs
(monitoring pressure, temperature,
and power transducers), as well as
traditional power transducers. The
9330 and 9350 can accept input
pulses from gas, water, steam, or
other metering equipment and convert
pulses into actual consumption values.
Residual Current
When set to 4-Wire Wye, any of
the meters can calculate neutral or
ground current based on three phase
current measurements.
Logging and Recording
The 9330 and 9350 provide data and
event logs. Non-volatile memory ensures
that valuable information can be
preserved between intervals when the
logs are retrieved via communications.
Historical Logging
Any combination of measurements
can be recorded at scheduled intervals
or by setpoints, logic conditions or
manually. Standard 30 days of recording
capacity at 15 minute interval data.
Defaults: all basic power parameters
and total harmonic distortion every
15 minutes
The 9350 offers 6 data logs, each
recording up to 16 user defined
parameters concurrently, for a
total of 96 parameters
The 9330 offers 2 data logs, each
recording up to 16 user defined
parameters concurrently, for a
total of 32 parameters
Min/Max Logging
Perform min/max logging on any
parameter, over any time interval
(e.g., daily, monthly)
Easily record other values coinciding
with the new minimum or maximum
Defaults: min and max for all basic
power parameters. Voltage (l-l/l-n)
per phase, Current per phase, kW,
kVAR, kVA, Power Factor, Frequency,
and Sliding Window Demand for kW,
kVAR and kVA
Event Logging and Alarming
Configurable event priorities allow
you to define alarm conditions.
Sequence-of-events time-stamped
to ± 10 ms accuracy and 1 ms
resolution
Time-stamped record of all
configuration changes, setpoint
and min/max events
Waveform Recording
The 9350 simultaneously captures
events on all channels, up to 48
cycles each
Resolution: 64 samples per cycle
Sag/Swell Monitoring
Detect sags or swells on any voltage
channel and record instantaneous
values and waveforms with the 9350
