Power-off reset actuators are mainly divided into three types according to the reset power and structural form: spring return type, capacitor return type, and backup power return type.
The spring return type achieves rapid power-off reset through built-in spring energy storage, with a simple structure and high reliability.
The capacitor return type uses supercapacitors for short-time power supply, featuring stable operation and precise position control.
The backup power return type is equipped with independent batteries or emergency power supplies, offering more flexible reset stroke and time, and can meet the safety reset requirements under long-stroke and high-torque working conditions.
