ACI Power Meter Current Transformers (Revenue Grade)

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 Revenue Grade Solid and Split Core Current Transformers are designed to convert an AC operating current into a low-voltage AC signal for use with microprocessor-based circuits that require maximum accuracy and precision. All of the Revenue Grade CTs come standard unterminated with ferrules for easy connection to any of the Single or 3 Phase power meters. The Revenue Grade CTs should only be used with the Powerscout™ PS3037, PS24, PS12HD, PS48HD Power Meters in Revenue Grade or Tenant Billing Applications. For best accuracy, the CTs should be selected based on the actual Window Size and the minimum and maximum operating currents for the circuits being monitored. Rocoils™ should be used in applications in
which the operating currents are in the 400A or greater range since using more of the output scale on the Rocoil™ will provide increased resolution than when used to monitor low current circuits.

The CT-RGT12 Series solid core current transformers should be used in applications where exceptionally accurate signal transformation, low phase shift while exposed to harsh environmental operating conditions since it is epoxy encapsulated. The CT-SRS and CT-SRL Series current transformers include a split-core design and superior performance with a robust, easy-to-use shrouded snap, lock, and tilt top for easy installation in retrofit applications. The CT-Rxx-A4-U Series otherwise known as the flexible Rocoil™ CTs are designed for use in typical applications up to 5000 amps maximum dependent on the Model number of the power meter in which they will be used with. The Rocoil™ CTs have been designed for accurate and non-intrusive installation of AC current, pulsed DC or distorted waveforms where conventional rigid core CTs are unsuitable. The Rocoils™ provides excellent frequency response over a dynamic range and do not require the use of an external VDC power source due to the onboard signal integrator/amplifier in each of the power meters. Extending the leads on all of the Flexible Rocoils and Revenue Grade CTs can be done in the field as discussed in the Current Transformer Lead Extension technical whitepaper or ordered from the factory for an additional cost and lead time.

The Revenue Grade Current Transformers are covered by ACI’s One (1) Year Limited Warranty.
