Precision Resistance Tolerance +/-0.1% +/-0.5% +/-1% +/-5% +/-10%
Good for both High Power Continuous Loading and Short Time Overload application
It can customize as High Current Resistors to handle very High Loading Current, up to hundreds Amperes, for even higher current requirement
It can be as Load Resistors for Load Bank
Resistance value can be according to customer’s application need
Support multi-resistances Resistor ( Multi Tab Terminals )
Support very small ( milli ohm ) and high resistance range
For very small resistance application, please tell your maximum Current and loading time.
For High Resistance value, please tell your maximum Voltage
