37 / 58 page  Preview Current shunt resistors are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create across the resistance. Sometimes called an ammeter shunt, it is a type of current sensor. A wide range of precision shunts, designed for use with kilowatt-hour meters and other high-current applications where a high level of accuracy is required, is now available from Token Electronics. The interchangeable shunts (FL) are used to multiply the measuring range of measuring instruments and designed for PCB and busbar mounting, are manufactured from electron beam welded copper and manganin, and have low temperature coefficients. Featuring low inductance values, shunts FL series can handle permanent currents of up to 10000A at voltage 75 mV. FLQ-54 type shunt is made of precision alloy board. It’s copper terminals spot welded by silver alloy ensure extremely high electric capability. The construction provides a kind of excellent stability and high overloaded ability non-inductive resistor, applied widely as current limited, current balance or sampling sense in communication system, electric equipment and auto-controlling electrical circuit. The FL Series is available in bulk packaging and is RoHS compliant and lead free. For non-standard technical requirements and special applications, please contact us with your specific needs. FL Current Shunt Resistors Token’s Shunt Resistors (FL) for high-current applications aid precision measurement. Current Shunt Resistors Power Rating : Watts (W) = Current (I2) x Resistance Value (R) - The heat produced is power measured in Watts (W). - In practice current shunts are often rated to be used continuously at only 2/3 of their “rated current”. - Because current shunts are resistors and dissipate heat from the current flowing through them, they get hot. - Since that heat can change their resistance and even permanently damage the shunt, current shunts are often given a power rating or a derating factor. Calculate Current : Current (I) = Voltage (V) / Resistance Value (R) - Then knowing the resistance of the current shunt you can calculate the current using Ohm’s law. - By inserting a current shunt into a circuit whose current you want to measure your can find the current by measuring the voltage drop across the shunt. 35 of 56 Version 2010 http://www.token.com.tw/ rfq token.com.tw TOKEN |
