Inrush current limiters (ICL), also known as inrush current limiters, are devices used to control an electronic system\'s inrush current when powered on. One of the most common models of ICLs is the SL22 60003. This section will explain the application field and working principle of the SL22 60003.

The SL22 60003 is designed to limit inrush current of up to 600mA in current-sensitive equipment operating under normal mains supply conditions. It is suitable for use in a wide variety of electronic devices, such as television sets, video recorders, power supplies, light dimmers, motor controllers, and heating systems. Additionally, the SL22 60003 is ideal for use in a photovoltaic (PV) system that utilizes an unregulated DC-AC power electronic inverter.

The SL22 60003 is equipped with two bidirectional bipolar thyristors. When the device is powered up, the thyristors gradually conduct, allowing a controlled buildup of current, thus preventing the device from drawing an excessively high inrush current. When the voltage on each of the thyristors rises to the turn-on voltage, the current brake turns off automatically. This allows the system to draw an appropriate amount of current, which in turn reduces the risk of failure due to excessive current.

The SL22 60003 also incorporates a temperature-compensated soft-start facility to ensure smooth operation. This soft-start ensures that the current drawn by the device remains within the specified limit regardless of external temperature. The device is designed to reach its final steady-state DC current levels faster than conventional methods, resulting in improved system reliability.

The SL22 60003 is designed for dependable performance with minimum maintenance requirements. It is vibration-resistant and has a long service life, making it ideal for use in SMD (Surface Mount Devices) applications. The device also meets strict safety standards, making it suitable for use in locations exposed to high electrical noise.

The SL22 60003 is robust and reliable, providing versatile protection against inrush current. It is compatible with a wide range of systems, making it suitable for a variety of applications, from household electronics and office equipment to industrial machinery and photovoltaic systems.

In conclusion, the SL22 60003 is an effective and reliable inrush current limiter. It is designed for a wide range of industrial and consumer applications, providing reliable protection against inrush current. Its innovative design ensures smooth operation and improved system reliability.
