SWITCHBOARD INSTRUMENTS
Yo kogawa offers a complete line of switchboard instruments to
meet your every needs.
Model are available 110 mm and 80 mm square size 250° to mea-
sure all electrical quantities.
All switchboard instruments in the series feature rugged, friction
free and shock resistant taut-band suspension elements.
All model of AC instruments except 80 mm size wattmeters and
varmeters are self-contained transducer needless external trans-
ducer boxes.
The built-in transducer system offer many advantages including
low cost, linear scales, greatly reduced volt-ampere loss.
Yo kogawa switchboard instruments offer a variety Models, such
as from single phase to three phase four wire instruments, as well
as model for balanced and unbalanced circuits. All instruments
except synchroscope are complied with JIS C 1102.
Features
■ RMS rectifier type AC instruments
■ Platform scale --- No shadow on scale and readable, even
from sharp angles
■ Interchangeable scales save time
■ Easy to read linear scales and wide deflection angles
■ Taut-Band suspension --- eliminate friction and protects
against shock
■ Unti-framable case and terminal board
■ Provide terminal protect cover for safety
