The GH AC Watt and Watthour Transducers provide an analog output proportional to time-averaged instantaneous true power and a relay closure or TTL pulse output calibrated in terms of Watthours of energy consumption by the load. Accuracy is ±0.2% of reading over a wide temperature range. Additional features include 1-, 2- or 3-element configurations, and bidirectional watt/watthour output. (read more)

The DMT 1024 and DMT 1042 are programmable, multifunction transducers with an RS-485 bus interface and Modbus^® protocol. These DMT Electrical Multifunction Transducers can measure and supervise several variables of a poly-phase electrical system simultaneously and generate four proportional analog outputs. (read more)

GW5 and GV5 Precision Transducers are designed for measurements within ±0.2% of reading accuracy in single or polyphase systems. The Model GW5 Watt Transducer provides power measurements, while the Model GV5 VAR Transducer imparts reactive power measurements. The electrically-isolated DC output is proportional to the instantaneous power averaged over several cycles. (read more)

GWV5 Precision Transducers provide reading accuracy within 0.2% for AC Watts and VARS over a wide temperature range. Models are available in 1-, 2- or 3-element configurations. Applications include integration into energy management systems and sub-metering systems; measurement using direct connection, current transformers, and/or potential transformers; and sinusoidal waveforms.

The Model P Variable Frequency AC Watt Transducer is accurate from 5 to 500 Hertz and available in both single and three phase configurations with bidirectional output, as well as split-core current sensors. Applications include accurate monitoring of power that contains DC and non-sinusoidal AC components, variable frequency drives, phase-angle-firing circuits or frequency synthesi... (read more)

Model W and W4 watt transducers are available in many models covering 0-600 volts and 0-1000 amperes. One, two and three element transducers are available for all single phase and three phase power systems. All models provide an isolated analog output for instantaneous watts and relay closure or pulse output for watthour consumption. Applications include energy management systems. (read more)
