Unlike current limiter that uses only a resistor, this current limiting circuit doesn’t drop the voltage, or at least keep the voltage drop at minimum, until a certain current amount is exceeded. This current amount limit is adjustable from 1.4 A to 8.4A using a potentiometer.
The same is true of the current limiters using within regulated power supplies. There are two main types of current limiter circuit: Constant current limiting : Using constant current limiting, the output voltage is maintained as the current rises until a point is reached where a maximum is reached. At this point the current maintained at this level whilst the voltage falls with increasing load.
Here is Current Limiting circuit. This is a 1 amp variable voltage PSU. It adjusts from about 3v to 24v: and has the added feature that you can limit the maximum output current. This is invaluable when (for example) you power up a project for the first time or soak test a piece of equipment. SW3 is the on off switch.
R1 (Limiting Resistor) = Vref current or R1 = 1.25 current. Current may be different for different LEDs and can be calculated by dividing the optimal forward voltage with its wattage, for example for a 1watt LED, the current would be 1 3.3 = 0.3amps or 300 ma, current for other LEDs may be calculated in similar fashion.
The switches allow the load current to increase to a programmed limit but no higher. Typically, the current limit is a function of the voltage across an external resistor, produced by the current from a fixed source internal to the switch IC.

Since the Current Limiter (CL) depends on current to rapidly heat the filament and increase its resistance, you need a bulb with higher filament resistance. ... Also, in my wiring diagram within ...
CLICK ON "Active Current Limiter" RTCA DO 160 can require large capacitors to hold up critical circuits during power interruption testing. DO 160 also requires the device stay under a certain ...
Connect the current limiter in series between the component that you wish to limit its current and the voltage source. If red clip is connected to posive terminal, the black clip must connected to Vcc of the component. Check before apply some voltage. The photo show I dimming a 3W LED with a current limter.
Current limiting is the practice in electrical or electronic circuits of imposing an upper limit on the current that may be delivered to a load with the purpose of protecting the circuit generating or transmitting the current from harmful effects due to a short circuit or similar problem in the load .
1. A simple, widely used current limiter consists of a current sensor (usually a low value sense resistor), a control circuit, and a pass transistor.
