250Nm, 12rpm 1-phase with hand crank & digital limits
The self-braking worm gear makes the Sidone irreversible. No need for an electric brake
Duty rating
There is a relation between the weight of the door and the number of movements per hour so the motor duty rating varies according to the door weight.
Overload safety factor
Motor overload safety factor = 4 x the nominal motor amperage because the starting current of the Sidone can reach these levels for short periods.
Output speed
The maximum admissible speed depends on the construction and type of door. The admissible closing speed shall be tuned so to let the operating forces comply with the EN 12453.
Manual operation
The manual override devices (handle or hand chain override) when power cuts-off, are based on a max strength of the end user of almost 40kg. In big or extremely heavy shutters the manual override is only intended in down direction.
