| Model：DAC-IR-3
DAC-IR-3 is designed to measure electromagnetic steel sheet
for Core Loss. Compared with a conventional Epstein Testing
Method, DAC-IR-3 is easier and also saves time.
DAC-IR-3 provides a Direct Reading of Core Loss in W/kg or
W/lb from a single sheet sample.
RS232C Interface is equipped as standard and can be controlled
by Personal Computer. Besides, measured results can be printed
with an optional thermal printer.
Features：
By placing a U-shaped yoke, which is wound with an exciting
coil and a magnetic flux detection coil, on a test sample,
a magnetic path is formed. When the sectional area of the
U-shaped yoke’s magnetic path is sufficiently larger than
that of the sample, and impressing a voltage to the exciting
coil effects excitation, the loss calculated by multiplying
the current flowing in the exciting coil by the voltage generated
in the flux detection coil can be considered the loss within
the sample.
This tester adjusts the flux density of the sample automatically
for measurement and gives a direct readout of iron loss value,
simply by using selector switches to set the sheet thickness
and flux density measurement desired.
Core Loss=Loss in the test sample
The effective weight of the magnetic path in the test sample
is the product of the sample thickness, and the magnetic path
width, length and density in the sample.
In this tester the width and length of the magnetic path are
constant, so that the core loss can be obtained by simply setting
the sheet thickness and flux density.

How to use：
① Setup parameters, Core Type, Flux Density, Thickness
and Frequency to print out automatically.
Example： S, 1.0T, 0.50mm, 50Hz
② Press MEAS ON Button after the measured value is stable
and test result is printed out.
