2039 Portable Power Factor Meter
Brand: Yokogawa Electric CorporationModel 2039 is a revolutionary series of portable watt meters in which a power factor is used to operate the DC indicator.
This is done using a transducer which provides a DC current proportionate to the voltage-current phase by means of a circuit. Model 2039 can be used in single-phase and balanced threephase circuits.
The Electronic Transducer, combined with a high sensitivity moving coil type indicator based on YOKOGAWA's proprietary taut-band suspension system, provides a level of performance not possible with conventional power factor meters.
Features- For Both Single-Phase and Three-Phase (Balanced Circuit)
- Excellent Current Characteristic: 20 to 200% of Rated Current (Short Time Period)
- Wide Range of Applicable Voltages: 60-300 Vac
- Phase Angle Scale Included
- Taut-band Suspension System Eliminates Friction and Provides Strong Resistance to Shock Impact
