High power resistor of BZ6D(RT300) type DC comparatorDetailed product description：

The BZ6D (RT300) DC comparator high-power resistor is a DC high-power standard resistor simulated by electronic circuits using DC current comparator technology, which solves the problem of power limitation of physical resistors. It can be used as a standard for circuit resistance testers and transformer rapid testers. It can also be used as a standard meter for DC high current meters. When paired with a DC high current source and a digital voltmeter, it can also be used to calibrate splitters (resistors) and as a range extender for QJ55.
