Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

Because these voltages are equal, we see in Equation 2:,. The entire circuit acts like a resistance between the IN+ and IN- terminals. Equivalent resistances looking into the IN+ and IN– terminals are ...

This constant resistance dummy load has not yet been tested in the real world. [YS] was inspired to come up with the circuit after reading Wednesday’s Re:load dummy load post. That was a cons… ...

But to test a 300-A, 0.8-V power supply, at least four 63640-80-80 load modules must be combined in parallel—both to achieve an effective on-resistance below 2.7 mΩ and to handle the total current.

Negative-Resistance Load Canceller Helps Drive Heavy Loads March 19, 2001 Though not difficult, driving a load from a voltage reference IC requires some attention.
