What is peak let through current?
Peak Let-through Current (See Figure 14) – The maximum instantaneous current that passes through an overcurrent protective device during its total clearing time when the available current is within its current-limiting range.
What is the function of a current limiter?
Current limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload. The term “current limiting” is also used to define a type of overcurrent protective device.
Why do power amplifiers only limit the current?
Most power amplifiers only limit output current to the maximum current the amp can supply. This simple measure primarily protects the amplifier itself without much regard to the downstream load circuitry.
What does current limiting mean in electrical circuit?
Current limiting. Current limiting is the practice in electrical and electronic circuits of imposing an upper limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload.
What happens when you put a limiter on your power?
With a limiter, you’ll have enough power to run heat, a few lights and a major appliance such as a fridge. As long as you stay within the limit, your power will stay on. If you use power that exceeds the limit allowed, the limiter will shut off your electricity.
Is the lt1970 op amp variable current limiting?
Snap, crackle and pop are the last sounds you ever want to hear when working with high power circuits, but such disturbing noises can be prevented by the new LT1970 op amp with variable current limiting. Electronics designers do not often celebrate at the sound of components being overdriven to their demise.
