Inrush Current Limiters (ICL) - SL05-5R003 Application Field and Working Principle

Inrush current limiters (ICL) are electronic components designed to limit the maximum amount of current delivered when a power supply is connected. The SL05-5R003 is a type of inrush current limiter developed by Master Instrument Corporation, which is specifically designed to protect power supplies from inrush currents. The SL05-5R003 is designed specifically for AC power sources, and features a wide voltage range and adjustable current limits. This article will discuss the application field, functional principle and features of the SL05-5R003 inrush current limiter.

Application Field:

The SL05-5R003 inrush current limiter is designed for protection of a variety of AC power sources. It is commonly used in:-Home appliances-Professional Electronics-Lighting Control systems-Industrial Equipment-Computer Systems-Power SuppliesThe SL05-5R003 is ideal for these applications due to its wide voltage range, adjustable current limits and small form factor.

Functional Principle:

The SL05-5R003 is based on traditional inrush current limiter design, which consists of two components; a resistive element and a semiconductor switch. When the power supply is first connected, the resistor acts as an interface to the power supply, with the semiconductor switch remaining closed. This keeps the inrush current to a minimum and allows time for the power supply to reach its operating state. When the power supply reaches the optimal voltage, the semiconductor switch is opened, the inrush current is instantly limited and the power supply is protected from possible damage.

Features:

The SL05-5R003 is designed to be used in AC power systems and features a wide voltage range (85-277VAC). The maximum voltage of the SL05-5R003 is 277VAC while the minimum voltage is 85VAC, and the current limit is adjustable from 150mA to 8A.The SL05-5R003 is designed to have a fast response time of 15µs, making it ideal for use in rapidly changing circuits. It is easy to install, with a small form factor to save space, and can be installed horizontally or vertically. The SL05-5R003 also features an LED indicator to easily show the state of the inrush current limiter.In addition, the SL05-5R003 has an industry-leading 10-year warranty, showing Master Instrument Corporation’s commitment to product quality and satisfaction.

Conclusion:

The SL05-5R003 inrush current limiter is a reliable and cost-effective solution for AC power system protection. Its wide voltage range, adjustable current limit, small form factor, fast response time and long-term warranty make the SL05-5R003 an ideal choice for a variety of AC power systems, including home appliances, professional electronics, lighting control systems, industrial equipment, computer systems and power supplies.
