Roller shutter controller, AC motor STR-3D

Roller shutter controller for comfortable operation

The STR-3D roller shutter controller is a universal device designed to control window roller shutters, blinds, and other 230V electrically driven devices. Mounting on a 35 mm DIN rail simplifies installation in a distribution box. The controller offers both local and central control, making it an ideal solution for both homeowners and installers.

Flexible control and additional functions

The device allows operation in single or dual local button mode, and also enables integration with central control systems. The shutter lock function, activated by pressing and holding the "Central – Down" button, provides additional security – e.g., when arming the alarm or in strong wind. The controller works with external rain and wind sensors (available separately), allowing automatic response to weather conditions. Asynchronous start minimizes inrush current when multiple shutters are started simultaneously.

Product characteristics and application

The STR-3D controller is characterized by low standby power consumption (below 0.15W) and a wide power supply voltage range (100÷265V AC). The ability to program the on-time (from 1 second to 15 minutes) allows you to adapt the operation to individual needs. Made of thermoplastic material with a matte finish, it is resistant to mechanical damage. Designed for 230V AC motors with a maximum power of 320W. The IP20 protection class provides protection against accidental contact, but does not protect against water ingress.

This controller has a number of technical features that affect its performance and safety. It provides compatibility with rain and wind sensors, enabling automated shutter control depending on weather conditions. It offers flexible control options – local (single or dual button) and central – adapting to different user needs. Made of durable thermoplastic and with an IP20 protection class, it guarantees reliable operation and safety.
