Power Metal Strip® Meter Shunt Resistor Power Electronics
The WSMS3124 meter shunt resistor features a proprietary processing technique that produces extremely low resistance values from 100 µΩ to 750 µΩ. These values allow for increased accuracy in current meter shunt applications for industrial and consumer single- or multiphase energy meters.
resistors - What is the role of shunt in a Power Meter
Power is the product of the voltage applied to a load and the current consumed by it. The shunt is low value resistor that may only be a small fraction of an ohm (depending upon the load current). This example is designed for currents up to 100A and so the value of the shunt may be just 500 micro-ohms.
it is a precision resistor having very low resistance.shunt resistor are low resistance connected in parallel with ampere meter whose rating is to be extended. shunt bypass the maximum amount of current and power rating of shhunt must be large enough to desipate the power.these are used with DC and AC both meters.it is an electrical conductor which is used with Analog /Permenant magnetic moving coil meters.
Apr 08, 2014 · Fig. 1Measuring current with a shunt resistor and a volt meter. Shunt resistors are often used in cases where currents need to be measured. They can be found in multimeters, as terminating resistors on current transformer or as a separate measurement accessories.
Measuring current with shunt resistors - Power Electronic
Measuring current with shunt resistors. February 26, A shunt is a low-value resistor used to measure current – it is therefore also referred to as a current-sense resistor. The shunt typically connects in series so it carries the current of interest. The Power Electronic eNewsletter delivers breaking electronic and power component
The PSB ultra-precision power shunt resistor series from Alpha Electronics offers 4-terminal (Kelvin) connections for current sensing and a power rating of up to 40W on a heat sink or 12W in free air (at +25°C) all with a low ohmic resistance range from 0.001ω to 1ω.
What is a meter shunt? A meter shunt is a useful means of extending the current range of an ammeter. As current divides between two resistors in parallel it is possible to increase the range of a DC microammeter or milliammeter by paralleling an additional resistance with the inherent DC resistance of the meter itself. This is called a meter shunt.
Shunt Resistor Delivers Values Down to 100 μΩ Power
Vishay Intertechnology’s WSMS5515 is a power metal strip meter-shunt resistor that uses a proprietary processing technique to achieve values as low as 100 μΩ with values extending up to 500 μΩ. This low-resistance capability enables increased accuracy in current meter shunt applications for industrial and residential electronic power meters.

How to make a shunt current resistor from Electroboom
HH2002 Multimeter and AC clamp meter. Parts you would need to make a low-voltage shunt resistor. Solid 22 AWG Wire. Wire Stripper & Cutter. If you want to measure the current from your circuit using your shunt current resistor using a low cost PC-based oscilloscope you can find a great option for a two channel 20 MHz pc oscilloscope here
What is Ammeter Shunt? - Definition & Shunt Resistance
As the shunt connects in parallel with the ammeter, thus the same voltage drop occurs between them. The shunt current is Therefore the equation of shunt resistance is given as, The ratio of the total current to the current requires the movement of the ammeter coil is called the multiplying power of the shunt.
The shunt usually has markings on the device itself stating what voltage will be created to achieve a full scale reading. As an example it may say 50 millivolts for 75 amps. This means if 75 amps of current travels through the shunt terminals, there will be 50 millivolts measured across the meter terminals.
Home-Made Current Shunts for Measuring Motor Current
Feb 25, 2006 · If the meter says 15.3, then you are drawing 15.3 amps. How cool is that! The other shunt works the same way, but since it is a 10mV per Amp shunt, you have to divide the value in the display by 10. In the above example, the meter will read 153, which you would divide by 10 to get 15.3 amps.
Ammeter Design DC Metering Circuits Electronics Textbook
The shunt resistor providing this high current range is enclosed within the metal housing of the meter. Note also with this particular meter that the needle centers at zero amps and can indicate either a “positive” current or a “negative” current. Connected to the battery charging circuit of an automobile,
What is a Shunt Resistor? - Definition & Formula - Circuit
Shunt Resistor DefinitionA resistor having a very low value of resistance such type of resistor is called shunt resistance. The shunt resistor is mainly made of the material having the low-temperature coefficient of resistance. It is connected in parallel with the ammeter whose range is to be extended.
