Aci KW350-P1-D-S-RC Power Meter 3 Circuit Bacnet Modbus Rtu

Product Description

The ACI KW350-P1-D-S-RC is a bi-directional power meter designed for three-circuit electrical energy monitoring in commercial and light industrial applications. It delivers ANSI 0.5 Class measurement accuracy and accepts Rogowski coil inputs, supporting monitored current up to 5,000 amps and voltage up to 690 VAC. The meter communicates over both BACnet MS/TP and Modbus RTU serial protocols, making it suitable for integration into building automation systems and energy management platforms. An onboard LCD display provides local readout without requiring a connected device. Licensed electricians and building automation technicians are the primary installers.

This meter is used in commercial buildings, industrial facilities, and multi-tenant applications where submetering or energy cost allocation is required. Its bi-directional capability supports installations with on-site generation or grid-tied renewable sources, where both import and export power flows must be tracked. The three CT inputs allow simultaneous monitoring of multiple circuits from a single device, reducing hardware overhead in panel-level metering installations.

Key Features

• ANSI 0.5 Class accuracy for revenue-grade or near-revenue-grade energy measurement
• Bi-directional metering supports import and export power flow tracking
• Three Rogowski coil inputs allow flexible, non-invasive current sensing up to 5,000 amps
• Dual serial communication: BACnet MS/TP and Modbus RTU on a single device
• Monitors voltage up to 690 VAC for compatibility with low-voltage distribution systems
• Onboard LCD display enables local readings without external software or tools

Compatibility

Designed for use with Rogowski coil current sensors in three-circuit metering applications supporting BACnet MS/TP or Modbus RTU building automation and energy management networks.

Installation Notes

Installation should be performed by a licensed electrician familiar with metering equipment and applicable NEC requirements. De-energize the circuits under measurement before connecting current sensors or signal wiring. Rogowski coil inputs must be oriented correctly relative to current flow direction to ensure accurate bi-directional readings. Serial communication wiring should follow the network topology requirements of the connected BACnet or Modbus system, including proper termination and addressing.
