2039 Portable Power Factor Meters
Model 2039 is a revolutionary series of portable wattmeters 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: 20~200% of rated current (short time period)
Wide range of applicable voltages: 60~300 V AC
Phase angle scale included
Taut-band suspension system eliminates friction and provides strong resistance to shock impact.

Notes
1. For measurements exceeding the rated current (25 A), externally connect a current transformer
2241-2243 (page 9) to the 5 A terminal.
2. For measurement with a voltage exceeding 300 V, externally connect a voltage transformer 2261
or 2262 to the 120 V terminal. (page 9)
3. 2039 is not JIS-approved.
