- Model PowerBullet - Power / Energy Transducers



Line Powered 100/115/208/230V or 277/347/480/600V. AC Demand and Consumption Measurement. The PowerBullet™ comes as a power or energy transducer designed for monitoring demand and consumption in residential, commercial and industrial applications. It is a line-powered, phase-to-phase unit with outputs compatible with the Voltage or Pulse inputs of most measurement systems. The transducer outputs are directly proportional to kW/kVA for demand and kWh/kVAh for consumption. It takes into account Power Factor and True RMS Values and includes built-in Arc Flash protection.


  • Equipment Level Optimization - motors, compressed air and cooling compressors
  • Branch Circuit Mixed Load Types - lighting and computer equipment

Power Demand Models (Voltage Outputs)

  • kW and kVA – proportional voltage outputs (compatible with standard 5VDC Analog Inputs)
  • PF (Cos phi) and kVAR for Energy Audits – Calculated from resultant data (compound line)
  • Peak Demand – Resolution down to 1sec logging interval

Power Demand models are compatible with SmartReader 3 (single phase only) and SmartReader Plus 3 data loggers.

Energy Consumption Models (Pulse Outputs)

  • kW and kWh – Pulse accumulation outputs (compatible with 5VDC Counter Inputs)
  • Mixed and Balanced Load Types – Use where submetering does not exist
  • Revenue Grade Measurement – High accuracy over 15min logging interval

(Energy Consumption models are compatible with SmartReader 9 and SmartReader Plus 9 data loggers.)

The PowerBullet uses a miniature Rogowski flexible split-core current transducer which makes it small enough to fit inside disconnect enclosures, breaker panels or distribution boxes. Wide Mouth Alligator clips make it easy to connect to the line voltage terminals without tools.
