Power Measurement
|
|
Accura
3300 is a high accuracy digital power meter, suited to power measurements. The device is applied to a variety of applications, electrical
facilities, intelligent building system, factory, generator and etc, making
measurements of voltage, current, power, frequency, power factor, and demand.

|
|
|
Accuracy
|
|
The
measuring accuracy is the most important criterion to evaluate the reliability
of energy management system. Actually low accuracy makes it hard for customers
to precisely manage energy, causing inequality of energy between incoming
feeder and sum of load sides. Accura 3300 makes ±0.2% high accuracy measurements for voltage and current, and conforms to IEC62053-22 class
0.5S for power and energy. This makes it possible to solve the problem with
energy inequality.

Accura
3300 provides the information of power qualities, such as voltage/current THD,
harmonic analysis, and k factor.

CE/UL Safety and Reliability
|
|
The structure-
framework, circuit, fire - of Accura 3300 conforms to safety standard,
CE[IEC61010], UL[UL61010-2, 2nd edition]. Particularly the device
provides pass-through busbar, allowing CT leads to be terminated on the device.
This eliminates any possible point of failure at the device.

|
|
Communication[IrDA and RS485]
|
|
Accura
3300 provides two independent communication ports. One port provides RS485
communication which supports a variety of applications, such as energy management,
IBS, and SCADA. The Accura also has an optical IrDA port, allowing the device
to be set up and programmed using a UMPC. Just point at the meter with
IrDA-equipped UMPC, so customers can monitor measurements, harmonic graph,
vector diagram, demand trend, and oscilloscope.

True RMS Measurements robust to harmonics
|
|
Most
of energy environments consist of nonlinear loads, such as industrial load,
rectifier, power electronic device, electric furnace and etc. this causes fatal
distortion of voltage and current waveforms. Accura 3300 makes high accuracy
True RMS measurements for voltage and current distorted with harmonics.
|
|
|
|
Power Quality Analysis
|
|
Accura
3300 provides k factor, analysis of voltage and current up to 31st
harmonic, and realtime waveform of voltage and current.
|
|
|
|
Compatibility with Analog Meters
|
|
Accura
3300 mounts directly in ANSI C39.1[4” Round] or DIN 96. this is perfect for new
installations and for existing panels. In new installations, simply use
existing DIN or ANSI punches. For existing panels, pull out old analog meters
and fit the device in its cutout.

|
|
High Reliability Energy Management
|
|
The
most important point to evaluate the overall data reliability of energy management
is the accuracy of meters. Accura 3300 makes ±0.2% high accuracy measurements for voltage and current, and conforms to IEC62053-22 class
0.5S for power and energy. Energy management gives customers various services,
monitoring, cost curtailment, demand, energy planning, and etc.
