TCS2, TCS3, TCS14 CURRENT SENSING RESISTORS

Download PDF File

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 (0.1mR & 2W) and 350A (0.1mR & 14W) are standard.  Applications include:
Current detection in precise power sources, constant current sources, industrial power conversion circuits,
HEVs, fuel cells and constant electronic loads.

DERATING AND FREQUENCY CHARACTERISTICS FOR TCS2 & TCS3

RECOMMENDED INSTALLATION

Notes:

1.  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.
