ACI KW1850 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 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. Key functions include multi-tariff time-of-use (TOU), billing mode feature, and power quality analysis- see table 1 for additional measurement functions and parameters.

The meter has either 8MB (KW1850-P1-D-S) or 8GB (KW1850-P1-D-W) memory for data logging, recording system events, and over/under limit alarming information that can be retrieved via a serial connection or remotely by Ethernet, depending on the model selected. The KW1850 Series incorporates Snap-On CT technology which reduces polarity errors, installation time, and eliminate CT wiring configuration. For CT connection, the CTs are terminated and plugged directly into the meter using the provided connectors. The meter features a built-in LCD display and a five-button keypad designed to simplify setup and provide local readings of all measurements of meter data. Many of the advanced meter functions are accessed via the Accuview Software which requires an RS-485 to USB converter for the KW1850-P1-D-S to connect to a PC or laptop, or the KW1850-P1-D-W which utilizes either Ethernet or Wi-Fi.

The meter supports multiple user-selectable communication protocols, pulse output communication, 18 digital inputs, 6 digital outputs, and 2 alarm relays which allows seamless integration with data acquisition systems. The tamper-proof design is approved for revenue applications. The KW1850 Series is compatible with multiple Current Transformer input options, however, 333mV CT or Flexible Rogowski Coil CTs should not be intermixed within a specific meter. Current Transformers are sold separately as shown on the Hinged, Split Core, Solid Core, or Rogowski Coils CT product data sheets.

The KW1850 Power Meters are covered by ACI’s Five (5) Year Limited Warranty.
