Every now and then — in any hacker’s lab — the necessity to measure massive currents comes up. Most multimeters have a 10A vary, which is okay, but it surely typically has a big burden voltage and accuracy isn’t nice except you have got a reasonably high-end meter. And 10A may be limiting — generally the necessity to measure 50A @ 0.7V comes up. Effectively, this beefy, heavy-duty 200A present shunt is a good addition to any lab.
With a 10A per V output, any first rate multimeter can get exact present measurements. Energy this shunt with 24V and you’ll simply measure proper as much as the 200A restrict! Now that’s a whole lot of
The bandwidth of the measured sign may be essential, and this shunt has a bandwidth of about 7.5kHz — sufficient to do some low-frequency measurements, however principally helpful for big, power-hungry DC hundreds.
It was initially developed to assist measure an enormous DC energy provide, and this might simply be built-in right into a take a look at/measure setup for testing high-output energy provides, equivalent to widespread ATX PC energy provides. Many trendy ATX provides can simply output a whole lot of amps on the 12V rail, and this shunt can be very helpful in characterizing the output of those provides below heavy hundreds.
So should you want a dependable, well-built DC present shunt for below $25, test it out! Repowered Electronics additionally produce other merchandise designed for working with heavy-duty DC energy.
