STJH-HVAC-DAMPER-ACTUATOR-10NM-SPRING
HVAC Damper Actuator 10 Nm 24 V Spring-Return
Proportional control with mechanical return when power is lost.
- The stored spring energy provides a defined power-loss movement.
- Manual crank operation supports local adjustment without a live drive command.
Product Introduction
A spring pack stores energy during powered operation and drives the shaft to its return position after supply loss. The deeper housing accommodates that mechanism, while the analog input controls normal positioning.
