If you are wondering what the real advantage is of using a constant current versus other methods of energy delivery, then you might be surprised that there are many real-world uses of a constant current source. You might also be surprised that you already regularly use several of them.
LED Lights
These highly popular forms of lighting require a power source that is constant and does not fluctuate to avoid overheating in their casings. The constant power ensures that their brightness does not fluctuate as well as extends their lifespan for as long as possible.
Charging Batteries
When you are either charging batteries for the first time or recharging them after they have been depleted, you will definitely want to make sure that the power source being used is a constant one. Not only does this provide a more reliable and optimized charge, but you will also prolong the lifespan of the physical batteries themselves.
Sensor Devices
When it comes to gadgets that act as sensors, such as those used for temperature or pressure, the electrical current that they are receiving needs to be constant to ensure all measurements are accurate. The sensors cannot function properly if they are not provided a stable source of energy.
Safety Features
Just as with any other type of power source, there are significant safety features built into a constant current source. These act to protect such things as short circuits, and overloads, as well as protection from thermal overheating. You will find out just how valuable these truly are.
