• Patented AutoPhase technology actually corrects common wiring errors.
• Analogue and network models available..
• AutoPhase Advantage
• AutoPhase makes power transducer installation simple.
• There are over 40 ways to wire up a 3 phase, 4 wire kW transducer. For example, reversing the orientation of a CT flips the output waveform, tricking ordinary watt transducers into thinking there is a 180 degree phase shift. Or if CT and voltage inputs are mismatched, the transducer thinks there is a 120 degree phase shift. Either way, you have a problem.
• AutoPhase identifies the phases and polarity automatically and corrects for the error in software. This eliminates flashing "ERROR" lights, tedious and dangerous reconnecting of inputs. AutoPhase even tells you which CTs are reversed and which phases are mismatched!

AutoPhase is protected by US Patent 5,652,505

Accepts ProteCT Current Transformers with 0.333 V safe output that eliminates need for costly shorting blocks. Also accepts traditional 5 Amp out CTs

Available as a bare circuit board (OEM Applications), Transducer Module for mounting in your panel or pre-mounted in a NEMA-1 panel. Get exactly what you need.
