ACI KW320 Power Meters

Automation Components, Inc. (ACI) creates, manufactures, and distributes building automation sensors for the heating, ventilation, and air conditioning (HVAC) Industry. Dpstar is ACI Authorised Distributor in Malaysia. Our product lines include Temperature Sensors, Relative Humidity Sensors, Current Sensors, Pressure Sensors, Gas Sensors, and Wireless Sensors.

The KW320 meter combines high performance with ease of integration to provide a power and energy monitoring solution with 400 metering parameters. The KW320 series multifunction digital power meter is designed using modern MCU and DSP technology and its tamper-proof design is approved for revenue applications. It integrates three-phase energy measuring and displaying, energy accumulating, power quality analysis, malfunction alarming, data logging and network communication. The meter measures bidirectional, four quadrants kWh and kvarh. It provides maximum/minimum records for power usage and power demand parameters. All power and energy parameters can be viewed remotely via Accuview Utility Software to monitor various parameters.

The meter comes standard to be mounted in a 4″ Round or an IEC 92mm DIN Square form or has the flexibility to be mounted to 35mm DIN rail with the AXM-DIN adapter (See Accessories Ordering). In addition, the KW320 also has an optional upgrade that includes a NEMA 4X panel enclosure, pre-wired and labeled terminal for CT’s, terminal blocks for voltage input, and industrial grade fuses. The KW320-P1-D-W-RC-PC and KW320-P1-D-W-SC-PC optional upgrade is an all-in-one Plug n’ play Pre-Wired Panel Enclosure that provides a perfect solution for retrofit projects where metering space is not pre-designed in an electrical distribution panel.

The meter supports user selectable RS-485 serial Modbus-RTU, BACNet™ MS/TP, multiple Ethernet communication protocols, and pulse output communication allows seamless integration with data acquisition systems. This product provides demand measurement of Current, Active Power, Reactive Power and Apparent Power – see table 1 for all parameters monitored and metered. It also provides demand forecasting as well as the peak demand. The KW320 series meter can record the time and event regarding important parameter events such as the run time of the meter and alarm functions. Current input options are compatible with any 333mV CT or Flexible Rogowski Coil. Meters come standard with a three channel CT input to accurately measure neutral current. CTs are sold separately as shown on the ACI Split-Core, Solid-Core and Rogowski Current Transformer product data sheets.

The KW320 Power Meters are covered by ACI’s Five (5) Year Limited Warranty.
