Inrush Current Limiters (ICL) are an important part of the electrical power system, playing a significant role in reducing peak inrush currents during start-up. One widely used ICL is the MS22 30005-B. In this article, we will look at the application field and working principle of this device in more detail.

The MS22 30005-B is an ideal choice for protecting electronic components from the effect of inrush current. It is useful in single-phase and three-phase systems, allowing it to be used in electronic control systems, motor drives, HVAC systems, lighting systems, and other areas. This ICL also has a very wide input voltage range (200-480VDC/400-480VAC) and can accommodate a wide range of 0.5A-60A output currents.

In addition to this, the ICL offers a wide variety of features, including an adjustable current limitation of up to 50x inrush current, wide operating temperatures up to +105°C, high efficiency of up to 95%, and integrated Active ORing for MCU protection. The device also has an integrated bypass circuit for quick recovery time, and it has no power drain when in standby mode.

So, what is the working principle of the MS22 30005-B? Inrush current is caused when a high-impedance load is connected to an AC source. This inrush current can be limited by introducing a time delay to the AC connection. The MS22 30005-B uses a fast-acting thyristor switch to achieve this. When the switch closes, the circuit is connected to the AC source, and the current is limited by the resistor within the switch. This inrush current is then gradually reduced, allowing the circuit to reach its full operating capacity.

The MS22 30005-B also has a number of protective features. The device is current-limited, meaning it will shut off if too much current is drawn or if the temperature of the device reaches an unsafe level. The device also features over-voltage and short-circuit protection, and it can detect an open load and shut itself off.

Overall, the MS22 30005-B is a versatile device, offering wide input voltage ranges, wide operating temperatures, and a wide range of current output options. It is suitable for use in a variety of applications, and its wide range of protective features make it a good choice for those seeking reliable protection against inrush current. Moreover, its fast acting thyristor switch provides an effective means of reducing inrush current, allowing for safe and reliable operation.

It is clear that the MS22 30005-B is a highly effective device for limiting inrush current, and is a logical choice for those looking to secure their electronic components. With its wide range of features, it is a great choice in protecting against inrush current.
