Electronic Adjustable Electric Actuator 220V Power Supply 361LSA-20

361/381 SeriesElectric Actuators are fully electronic actuators that use AC220V single-phase power as the driving source. They directly accept control signals (DC4–20mA, DC0–10mA, or DC1–5V) from DCS, PLC systems, or regulating instruments to operate, performing angular displacement (0–90°).

361LSA-20 Electric Actuator Product Features

1. The actuator is designed with a built-in servo system (no additional servo amplifier required). It operates simply by connecting a DC4–20mA (or DC1–5V) signal and AC220V single-phase power. Internal terminal blocks make wiring extremely simple and convenient.
2. The controller, a key component of the actuator, uses advanced hybrid integrated circuits, sealed with resin casting. It features a compact box-shaped design with high reliability.
3. Feedback detection of the driving quantity uses a high-performance conductive plastic potentiometer with a resolution of <0.4%.
4. Equipped with self-diagnostic function; in case of failure, the indicator on the controller immediately signals an alert.
5. A status selection switch allows configuration for loss of signal (valve fully open, fully closed, or self-locking).
6. A status selection switch allows configuration for (direct or reverse action).
7. A status selection switch allows configuration of input signal (DC4–20mA or DC1–5V).
8. Easy adjustment of the working zero point (start) and travel (end point).
9. Ensures valve self-locking in case of sudden power loss.
10. Uses synchronous belt drive, effectively reducing noise.
11. Delay protection function: under rated load, the actuator can self-lock; in case of failure, protection is activated immediately, and reverse operation can cancel the delay protection.
