Helios Fans STM 20 24V 2P

The Helios STM 20 24V 2P is a robust electric servomotor designed for operating JVK volume control dampers. With a maximum torque of 20 Nm and powered by a 24V connection, this actuator ensures reliable damper positioning for ventilation and HVAC systems.

Equipped with spring return functionality, the STM 20 24V 2P automatically returns to its default position during power loss, enhancing safety and system reliability. It features two potential-free auxiliary switches that provide feedback on both open and closed positions, configurable to suit application needs.

Designed for direct mounting via a plug-in system on the damper shaft, this actuator also includes a mechanical position indicator, enclosed rotation limiter, anti-rotation lock, and two built-in auxiliary switches. Manual adjustment is possible using a hand crank and locking switch.

Built to be overload-proof and maintenance-free, the STM 20 24V 2P is ideal for demanding applications that require dependable, automatic damper control.
