Product Description:
623x series+6220+7721+6905 (transfermoer tester+DC Bias+Impulse/Surge tester+Hipot tester) 4 in 1 comprehensive transformer testing system，Add the DC bias to offer the “DC overlapping current source” function. To obtain the parameter of the coil of the to be measured DUT with overlap current through the DC bias function. To confirm the quality and the high stability of the products delivered from the factory, we have to realize the special features of the coil of the to be measured DUT with additional current.
