BGX701-014-R03, User Manual for PT3 Transducers
4 Introduction to three-phase transducers
The PT3 transducer is suitable for measuring, monitoring and analysing three-phase industrial and supply
applications. It is available with up to four analogue outputs and can accurately measure electrical quantities
such as current, voltage, active power, reactive power and power factor by converting them into proportional DC
current or voltage analogue signals (For e.g. 0-10 V, 0-2mA, 4-20 mA etc.). The output signal that is generated
is proportional to the true RMS value of the input signal.
Salient features
• Available in single-function and multi-function variants
• Available with high or low auxiliary power supply options
• Has two or four, galvanically isolated, load independent analogue outputs
• Has a loop impedance support of ≤750 Ω for current and ≥2 kΩ for voltage outputs (independent of
analogue outputs used)
• Provides a full-scale accuracy class of 0.2, 0.5 or 1.0
• Offers a response time of < 220 ms
• Offers fast sampling rates and accurate RMS measurements over a long range
• Measures V, I, PF, active and reactive power, load PF, apparent power and frequency
• Can be configured onsite for required input measurement range, output type (either mA or V) and curves
• Multiple functions can be configured as input for multi-function transducers. Different input functions can be
assigned for measurement to each of the four output channels or a single input function can be assigned to
all channels.
• Easily configurable through micro USB port without the need for power supply
• LEDs for signalling Power ON and diagnostics
• Top hat DIN Rail mountable as per EN50022
