AC/DC Measurement Power Measurement

Accura 3550 is a high accuracy digital power meter dedicated to rectifier, suited to power measurements and DC measurements. In rectifier, the existing customers obtain dc voltage and current from analog inputs of RTU after converting signals using separate tranducer. The signal conversion several times deteriorates the overall data reliability, and causes the rising of costs. The device simply replaces the existing RTU using Tranducer, solving the above two problems.

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 3550 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 3550 conforms to safety standard, CE[IEC61010], UL[UL61010-2, 2^nd 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.

Communication[IrDA and RS485]

Accura 3550 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 PDA. Just point at the meter with IrDA-equipped PDA, so customers can monitor measurements, harmonic graph, vector diagram, demand trend, and oscilloscope.

Measurement dedicated to Rectifier

Rectifier panel guarantees reliability of control power in energy system during the interruption of power. Accura 3550 is a high accuracy digital power meter dedicated to rectifier, suited to power measurements, DC measurements, and rectifier status.

True RMS Measurement 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 3550 makes high accuracy True RMS measurements for voltage and current distorted with harmonics.

Power Quality Analysis

Accura 3550 provides k factor, analysis of voltage and current up to 31^st harmonic, and realtime waveform of voltage and current.

Compatibility with Analog Meters

Accura 3550 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 3550 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, rectifier management and etc.
