PQT90, SPT90 Power Quality Transducers

In applications where power quality information must be obtained and no local display is required, a Carlo Gavazzi smart transducer is the ideal solution. Information can be transferred to a PLC or a PC via 4-20 mA signal or through RS485. Alternately, our transducers can be used stand alone by using the digital outputs as alarms.
