KW Series Power Meters


ACI has proudly supported the Heating, Ventilation, and Air Conditioning (HVAC) Industry since 1991. We are committed to providing high quality, Revenue Grade Meter to meet your power monitoring requirements. Our newest line of Meters and Current Transformers will provide your Building Automation System (BAS) with the power and energy usage data required to make informed decisions.

ACI Meters can target key areas to lower your energy costs. They provide additional value by reducing maintenance costs through predictive maintenance, identifying outdated and underperforming equipment, and calculating project Return of Investment (ROI). Power monitoring solutions are also available for use without a traditional BAS type monitoring system through the on-board data logging capabilities, enabling the data to be downloaded into an excel (.csv) spread sheet.


3 Different Meters to Choose From:

KW320

3 Channel Power Meter, 0.2 Class, Multi Communication Protocol

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.

  • Large, multi-function LCD
  • Single-circuit meter
  • BACnet MS/TP or IP, Modbus RTU or TCP
  • Programmable over WiFi

KW350

3 Channel Power Meter, 0.5 Class Accuracy, Serial Communication Protocols

The KW350 meter combines high performance with ease of integration to provide a cost effective power and energy monitoring solution. The meter comes standard to be mounted DIN rail mounted but is also available in a panel upgrade version that comes with NEMA 4X panel enclosure, pre-wired and labeled terminal for CT’s, terminal blocks for voltage input, and industrial grade fuses (see ordering grid). The meter can monitor both uni-directional and bi-directional current and features a built-in LCD display designed to simplify setup and local reading of all measurements of meter data. The user interface enables access to configure the meter set-up options. Many of the advanced meter functions connect with the Utility Software which requires an RS-485 to USB converter to connect to a PC or laptop

  • Lost cost, single-circuit meter
  • BACnet MS/TP or Modbus RTU
  • Built-in din rail bracket
  • Small footprint maximizes panel space
  • Programmable over WiFi

KW1850

18 Channel Power Meter, 0.5 Class Accuracy

The KW1850 Series DIN rail mounted meters combine high performance with ease of integration to provide an energy measurement and monitoring solution. The meter supports unidirectional monitoring up to 18 single-phase or 6 three-phase circuits simultaneously for multi-point energy measurement. The compact design is suited for high-density applications to be used in conjunction with commercial, industrial, and residential multi-tenant energy management systems.

  • Multi-circuit meter (Up to 6 three-phase circuits)
  • Built-in Din Rail Bracket
  • Class 0.5% accuracy
  • BACnet IP or Modbus RTU/TCP
