Most AC-DC power supplies and DC-DC converters have internal current-limiting circuits to protect the power device, and to some degree its load. The majority of over-current-protections include an ...

In Figure 1, a dc-dc boost converter with a built-in, possibly even adjustable, current limiter could also be used. In this case, the additional current - limiter block may be omitted.

If for example the LED is destined for 14 V, this device will not only show how the LED looks at the chosen current, but will calculate the required resistor to get the same results on a 14 V system.

The ARC family of non-inductive, high-voltage, thick-film resistors from Arcol is designed for demanding applications such as high-voltage power supplies and medical systems, test and measurement ...
