Overview
Cost-effective Power Meter Providing Digital/Analog Inputs and Outputs
Accura 3500S is an integrated digital power meter that performs power measurements and also
provides digital/analog inputs and outputs. It is cost-effective in that it perfectly suits the needs of
managing various digital and analog inputs and outputs in the field. Thus, Accura 3500S
eliminates the need to buy extra RTU products. It can be widely used in manufacturing plants, IBS,
semiconductor plants, etc, where power measurements and the management of inputs and
outputs are required.
Accurate Measurements/ Power Quality Data Available
Measurement accuracy is a key factor that determines the reliability of energy management
systems. Low measurement accuracy causes inconsistency between the energy of the incoming
feeder and the sum of energy measured on the load side. It makes it difficult to perform reliable
energy management. Accura 3500S provides highly accurate measurements of voltage and
current (
±
0.2% of reading) and meets IEC 62053-22 class 0.5S for power and energy
measurements. It helps to address problems caused by measurement errors and allows for
efficient energy management. Accura 3500S provides power quality data such as voltage/current
THD, harmonics, and K-Factor.
CE/UL Safety and Reliability
The internal and external structures(the product and circuit design) of Accura 3500S meet safety
requirements for CE(IEC 61010) and UL(UL 61010-2, 2nd edition) standards. The busbar
provided with the product allows for easier wiring of CTs when installing the product. The busbar
minimizes fire hazards by ensuring safety under an overcurrent condition. And the optic interface
between the meter and connected modules removes risks of electrical hazards.
