CURRENT SENSING RESISTORS

Using advanced welding techniques and nickel alloys these resistors have a long term stability of less than 50ppm/C. The simple four port Kelvin design ensures easy installation on large current busbars. Currents of 170A (0.1mR & 3W), 100A/C 0-50ppm/C Overload 2KW for 0.1 sec. 2KW for 0.1 sec. 2KW for 0.1 sec.

When TCS2, 3 is attached to a current bus, mechanical strain should be avoided. 2. Resistance is calculated using DC voltage on detecting terminal at application of current through current terminals. 3. Voltage out copper pins should be attached to the copper terminals of the resistor. ORDERING PROCEDURE EXAMPLE
