STA 1 FU/I series

STA 1 FU/I series

Our opener with a frequency converter for 230 V single-phase mains. The frequency converter generates the three-phase power supply required. Compared to STA 1 openers without a frequency converter, it opens doors twice as quickly. In conjunction with the soft start and soft stop function, the opener brakes the door gently, however, in the end positions, to ensure smooth, door-friendly operation. Speeds can be variably set for opening and closing the doors.

Standard hollow shaft and splined cog system

We offer systems with two different shafts. Both our inexpensive universal solution, the 25.4 mm standard hollow shaft and the hollow shaft splined cog are high-quality solutions. 

25.4 mm standard hollow shaft: Universal and economical. Our standard hollow shaft in 25.4 mm is a compact and economical all-round solution for most doors. The opener can simply be slipped onto the spring shaft of the door. The hollow shaft of the opener is made of steel. 

Hollow shaft with splined cog: The retrofit solution. The splined cog system is the optimal solution for retrofits. With the various shaft adapters, one opener fits a variety of spring shafts. That’s why this system offers minimum storage with maximum flexibility. The shaft adapters are made of aluminium. This ensures that they will not seize up due to rust. For hollow shafts with splined cog, existing adapters from the Dynamic xs. systems can still be used as well. 

Mains voltage 230 V FU

Mains voltage 230 V FU

Door opener 230 V, single-phase with a frequency converter: Quiet and powerful without high voltage. These openers are more powerful than the available mains power would suggest. It’s the frequency converter that gives it that extra boost. It generates the strong 3-phase mains voltage where only 230 V is available. This gives the motor the power it needs for large, heavy doors. It runs at twice the speed but still uses the door-saving soft-start and soft-stop function. We offer it exclusively in combination with our CS 310 external comfort control unit. 

External CS 310 comfort control unit

External CS 310 comfort control unit

The CS 310 is our external comfort control unit, which leaves nothing to be desired. It offers four output relays for additional functions. Use this, for example, for signal lamps, traffic lights, electrical door locking or the end position alarm. Other elements can be supplied with 24 V or 230 V power. Accessories are connected directly to the control unit. Multi-Bit radio is possible with the CS 310, and the slot for the standard antenna is already included.

Expand as needed: The control unit can be expanded through MS-Bus modules, for example, for oncoming traffic regulation or draw-in protection.

Even more safety: Safety equipment, such as photocells or a closing edge safety device can be connected via terminals.

Easy and comfortable: Easy, plug-in cable sets ensure comfortable installation. 

Length of use 60 % or 80 %

When choosing the right door opener, the load, or the length of use, is decisive in addition to the power. Here, we can provide you solutions with 400 V openers for average use doors or heavily frequented doors. 

60 % duty cycle: Normal duty cycle for 400 V openers. Designed for doors with average opening frequency. This corresponds to a maximum of 20 door cycles per hour. 

80 % duty cycle: Increased duty cycle for 400 V openers. Designed for doors with high opening frequency. This corresponds to a maximum of 30 doors cycles per hour. 

One cycle corresponds to opening and closing the door one single time.

Emergency operation of spring balanced doors (KE, E/KE)

Emergency operation facilities provide safety. They guarantee that a door can be opened and closed during a power outage.

KE (emergency hand chain): It provides standard emergency operation for openers with a standard hollow shaft of 25.4 mm. The emergency hand chain makes it possible to comfortably operate the door from the ground. 

E/KE (emergency hand chain with maintenance release system): The best and most comfortable solution: This is the standard emergency operation facility for openers with splined cog system. The emergency hand chain offers comfortable operation of the door from the ground. At the same time, the maintenance release system makes quick and inexpensive service possible, since there is no need for time-consuming disassembly of the motor or for detaching the opener from the shaft. 

Digital limit switch

An absolute value encoder guarantees precise travel cut-out. The end position of the control unit is not only conveniently set using the digital limit switch, it also keeps it correct.
