Power test systems are made for single-phase and three-phase power quality testing applications. Record and analyze power at any base frequency from milliHertz to 800 Hz, and still add any of the unique DEWETRON capabilities - video, GPS, additional analog sensors, etc. POWER QUALITY is as an add-on to just about any DEWETRON system, so please look at any of our multifunction systems as a platform.

The 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!

This HighDynamic-Range power meter is temperature stabilized, resulting in highly accurate and stable measurements. And, unlike other power meters that slow considerably when switching sensitivity ranges, it incorporates a patent-pending logarithmic conversion circuit that achieves essentially seamless range switching, resulting in a useful dynamic range of >65 dB even at full speeds-about 20-dB better than conventional power meters. We've even provided three user-controllable speed settings so you can further extend the dynamic range if you don't need the speed. The convenient bolt-together modular design and daisy-chained power connections makes it easy to connect multiple units for multi-channel rack-mounted or bench-top systems. The wavelength range for the Model 2101 is 320-1060 nm.
