STL: Ensuring system protection when the power goes off

STL Power & Process Controls have been the official Chanel Partner for RTK in the UK and Ireland for over 27 years.

The RTK PoP (Power off Position) is a series of electric actuators with a FAIL-SAFE FUNCTION.  They are uniquely designed to keep your system safe in any situation. 

Unlike other actuators, the PoP series offer 2 system-saving features in one actuator, that allow the actuator to reach a predefined safety end position (open/close), reducing the risk of system damage if the power is lost or a system failure occurs and to regain its full capacity in less than 60 seconds when power is restored.

Emergency Closing Unit

Allows the actuator to reach a predefined safety end position (open/close) if a system failure occurs.

Fail-safe function provided by super capacitors

Allows the actuator to reach a predefined safety end position (open/close) if the energy supply is lost, and to regain its full capacity in less than 60 seconds when power is restored.

With over 500,000 charging cycles, making it maintenance free, the PoP actuator combines system-protecting functions with convenient features and efficient performance.
