Belimo electronic fail-safe actuators were developed for the HVAC market using several patented technologies to provide reliable operation and new selectable fail-safe positioning. Unique electronics, software and super capacitor technology not only enables user selection of fail position (0-100%), but also delays unnecessary actuator movements during short brown out conditions - avoiding changes in the HVAC and building automation system.

Environmental and climate conditions often result in short power interruptions which can cause damper and valve actuators to begin fail-safe operation and temporarily destabilize the room or building temperature control. This causes unnecessary actuator movements and additional energy usage. The new electronic fail-safe actuator series with the control power-off function and durable, maintenance-free capacitors provide solutions to these climate conditions.

Like all Belimo actuators - the electronic fail-safe actuators are easy to install, commission, inspect and connect to higher level systems and have a complete line of accessories available.
