CL-120AB

Inrush Current Limiters (ICLs) are electrical components used to limit the start-up current of an electrical circuit, or to limit the inrush current upon energizing a circuit. CL-120AB is an Inrush Current Limiter that is widely used in many electronic devices such as computers and office appliances. This article explains the CL-120AB application field and working principle.

The CL-120AB Inrush Current Limiter has been designed to protect against a large electrical current surge during the power-on or off-on switching process of an AC power source. The current limiter prevents the current from exceeding a pre-defined limited value, allowing a slow start-up of the electronic device and prolonging its service life. The CL-120AB is able to limit the maximum current to 1000A and the maximum peak voltage to 110V.

The CL-120AB application field is mainly used for a wide range of AC/DC medical power supplies, household appliances, computer systems, industrial products and power products. It is also a suitable for use in all electronic products that require inrush current limitation. Such products include surveillance systems, digital signage systems, antennas, 3C products, and household appliances.

The working principle of the CL-120AB inrush current limiter is mostly related to electric circuit principles. The current limiter utilizes the principle of energy dissipation and electromagnetic induction to limit the peak inrush current of a power supply circuit. The CL-120AB current limiter comprises three parts: an inductance coil, a capacitor and a resistance. It works in the following way: when an AC source is powered on the inductance coil of the current limiter is energized. This energy induces a magnetic field, which creates a high voltage across the capacitor. The resistance controls the current, thus limiting the peak current that flows into the circuit. In this way, the start-up current surge is minimized.

In conclusion, CL-120AB Inrush Current Limiter is a widely used component for limiting the inrush current of AC/DC power sources. It is designed to provide a slow start-up of the electronic device and to protect the device from any damage caused by high peak current surges and voltages. It works by utilizing the magnetic field energy generated by the inductance coil to limit the maximum current to 1000A and the maximum peak voltage to 110V.
