Chapter 1 Introduction
Overview
Power Measurements, Digital/Analog Input and Output Integration
Accura 3500S is a high accuracy digital power meter, suited to power measurements
and digital/analog input and output. This enables customers to easily meet a variety of
digital/analog requirements in the field, remarkably cutting down expenses of customers
to additionally purchase separate RTU products in existing management system. The
device is applied to applications, such as electrical facilities, intelligent building system,
factory and etc.
Accuracy, Power Quality
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 3500S 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. Furthermore the device 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 3500S conforms to safety standard,
CE[IEC61010], UL[UL61010-1, 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. And optic interface between meter and module
essentially disturbs danger of the existing electrical contacts.
Easy Adding of Modules
Easy adding of modules to rear side of meter provides customized extension of function
to flexibly meet a variety of applications. Accura 3500S has a basic module, called
DIO module, and an extension module, one of digital input, digital output, analog input,
and analog output modules. the extension module is selected as an option when

ordering.

Applications
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 3500S makes high accuracy True RMS measurements
for voltage and current distorted with harmonics.
Power Quality Analysis
Accura 3500S provides k factor, analysis of voltage and current up to 31st harmonic, and
realtime waveform of voltage and current.
Module Structure to adapt to different requirements in the field
Easy adding of modules to rear side of meter provides customized extension capability
to flexibly meet a variety of applications. In the case of the existing IBS, DDC panel
concentrates all of input/output wiring, decreasing economical efficiency and reliability
of the overall system. Accura 3500S easily replaces the existing DDC panel, building the
optimal IBS system.
Compatibility with Analog Meters
Accura 3500S 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 3500S 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.

Chapter 2 Mounting
Environmental Conditions
The Accura 3500S should be mounted in a dry, dirt free location away from heat sources
and very high electric fields. To operate properly and effectively, environmental
conditions should range within the following guidelines
Items Acceptable Range
Position Indoor use
Operating Temp -20 ~ 70°C[-4 ~ 158]
Storage Temp -40 ~ 85°C[-40 ~ 185]
Operating Humidity 5 ~ 95% Non condensing
Enclosure Considerations
The enclosure the Accura 3500S is mounted in (typically a switchgear cabinet) should
protect the device from atmospheric contaminants such as oil, moisture, dust, and
corrosive vapors, or other harmful airborne substances. The mounting enclosure should
be positioned such that the doors may be opened fully for easy access to the Accura
3500S wiring and related components to allow for convenient troubleshooting.
Warning
The meter s
hould be installed in a switchgear cabinet or similar enclosure to ensure the
terminal strips on the meter base are not user accessible after installation.
Mount the meter in a dry location free from dirt and corrosive vapors. Once installed, no
cleaning of the device is necessary.
