AS35 20010

Inrush current limiters (ICLs) are devices used to hold the instantaneous inrush current to a safe level in most power systems and electronic circuits. The AS35 20010 is an ICL designed to provide a safe current limit suitable for many applications such as vehicle power supplies, USB/battery chargers, and electronic lighting systems.

The AS35 20010 is an SCR-based ICL with a current limit of 10A. It is a two-terminal device, meaning that it can be easily inserted into existing systems without the need for additional circuitry. The device is composed of an SCR-controlled resistive element and a capacitor and an operational amplifier used to time constant the inrush current. The maximum peak limiting current is set by selecting the value of resistor connected in series with the gate of SCR.

The working principle of the AS35 20010 ICL is based on the same principle as that of other ICLs. When the supply voltage is applied, it charges the capacitor to a voltage near the supply voltage. At the same time, the voltage across the SCR gate is also increased, causing the SCR to conduct. The current then is limited by the resistance of the resistor.

When the supply voltage is below the peak current limit, the SCR remains in a non-conducting state. However, when the supply voltage increases above the peak current limit, the SCR conducts and holds the current within a safe level. This ensures that the current remains within a safe level of current even at high voltages.

The AS35 20010 ICL provides reliable protection from transient overcurrents for a variety of applications. This includes protection for motor stalls, surge protection for vehicle power supplies, battery charging, and electronic lighting systems. It is also suitable for other high power applications such as solar inverters and substation control systems.

In addition, the AS35 20010 ICL is designed with a low power loss and low temperature coefficient, providing excellent thermal stability. It is also resistant to vibrations and shocks, ensuring a reliable operation in harsh and extreme environments. These features make the AS35 20010 an ideal choice for use in various applications.

In summary, the AS35 20010 is an efficient ICL providing reliable protection from transient overcurrents for a wide variety of applications. It can handle high currents without the need for additional circuitry and its low power loss and temperature coefficient provides excellent thermal stability. Additionally, the device is resistant to vibrations and shocks, making it an ideal choice for use in various applications.
