I. Introduction  

1-1 Summary

This instrument can measure the iron loss of electrical steel sheet. The Epstein Test is used extensively as the standard method for measuring iron loss. it requires, however, the preparation of special test samples and considerable time to make the required measurements.

The DAC-IR-2C is a Yoke Type Iron Loss Tester and has a great advantage compared to the Epstein method in that it provides a direct reading of iron loss scaled in watts per kilogram or watts per pound from a single sheet sample. It has been designed compact in size and simple to operate, thus is greatly helpful for quality management of steel sheets on various job sites.

Superceding the former portable type Iron Loss Tester DAC-IR-2 made in Japan SOKEN, DAC-IR-2C provides convenient and fast measurement of the core loss of Electrical Steel Sheet individual pieces and laminations of all sizes and shapes, simply by placing the probe. It measures the Iron Loss in W/kg indicating it on a large LED readout Display.

DAC-IR-2C can test the Min 5 mm of Width and the Max 0.99 mm of Thickness for any shapes of Electrical Steel Sheet.

1-2 Application

Acceptance testing by user and supplier of electrical steel for stamping，annealing and final assembly of laminated cores. The Tester can be used for identification of Electrical Steel Iron Loss grade or finished lamination cores refer to Fig 1.

1-3 Features

Portable, Light Tester with good reproducibility. Direct large LED readout of W/kg 50Hz. Simple front panel controls. Operation has been made more consistent with new Probe and Repeat Fixture. Magnetic flux density can be set at 1.5 or 1.7 Tesla selectable separately for Non Oriented or Oriented Grain Steel Sheet. The Power Supply AC Voltage is 100V or 220V/50Hz.
