The Practical Electronic Automatic Current Limiter (Model: HY01-B-220/35-100) is an intelligent protection device specially designed to solve the problem of huge inrush current generated during equipment startup. Through advanced automatic voltage regulation technology, it steadily raises the voltage during equipment startup, effectively suppressing the startup inrush current of up to 5-10 times the rated value, and providing reliable protection for your valuable equipment and power supply network.
The core of this product lies in its built-in automatic voltage regulation circuit board, which is connected in series with the load. Its working principle is as follows: At the moment the load is powered on and started, an automatic phase-shifting circuit controls the conduction angle of the thyristor, making the voltage across the load increase gradually and smoothly from a low value. After the preset startup time (3 to 3.5 minutes), the voltage reaches the rated value of the power grid, and the load enters the normal full-voltage operation state. This process is fully automated without manual intervention, and is especially suitable for load equipment with high startup current but whose current drops rapidly and stabilizes during normal operation. It effectively avoids circuit breaker tripping, equipment damage, and power grid voltage fluctuations caused by frequent high-current impacts.

It is mainly used to solve the problem of huge inrush current generated at the moment of startup of equipment (such as high-power motors). This current is usually 5 to 10 times the normal operating current, and although it only lasts for tens of seconds, it is easy to cause switch tripping, equipment damage and power grid interference. This product completely eliminates the impact of startup current by smoothly raising the voltage to full voltage through the "soft start" method.
