Inrush current limiters, or ICLs, are electronic devices that are designed to limit surge currents that flow into an electrical circuit when the circuit is turned on. These devices can be used for a variety of applications, including motor starting, inrush current protection, and controlling power spikes. The SG314 is a type of ICL that is ideal for use in applications where space is a premium, such as tight installations. It can also be used in laboratories, industrial settings, and other high-power environments.

The SG314 is a low-temperature, non-inductive, phase-controlling inrush current limiter. The device is designed to limit inrush current by gradually increasing the resistance of the device to the flow of current. This is achieved by an internal variable resistor that is controlled by an on/off switch. When the switch is in the “on” position, the variable resistor starts to reduce the resistance, allowing more current to flow through the device until the desired amount of current is reached. The SG314 is designed to operate at temperatures ranging from -40℃ to +60℃ and can handle voltage ratings of up to 1000V. It also has a maximum rated current of 200A.

The SG314 can be used in a variety of applications, including motor starting and inrush current protection. It is ideal for electronic motor applications, such as electric pumps, heating, and ventilation systems, that require precise control of the inrush current. It can also be used in other applications, such as laboratory settings, where it can protect sensitive equipment from power surges. The SG314 can also be used in medical equipment and other high-power environments.

The working principle of the SG314 involves the use of a thermistor that is connected to the inrush current limiter. When the voltage across the thermistor reaches a certain level, or threshold, it shortens the resistance of the limiter, allowing current to flow. This type of inrush current limiter is designed to be self-regulating and self-limiting, meaning that it will regulate itself and limit the amount of current that flows through the device.

The SG314 is a reliable and cost-effective solution for applications that require precise control of inrush current. It is also designed for use in a variety of environments, from motor starting to laboratory settings, and is capable of limiting up to 200A of current. This makes it an ideal choice for applications where space is a premium, as well as those that require additional protection against power surges. Overall, the SG314 is an excellent choice for applications where precise control of inrush current is required.
