12-channel stairwell and cascade controller 9-30V DC AS-225D

Staircase and cascade controller – an intelligent solution for your home

This 12-channel staircase and cascade controller AS-225D is a versatile device designed for building staircase lighting systems with a wave effect. Thanks to the ability to control up to 12 lighting points, it is ideal for both single-family homes and multi-story buildings. The device is compatible with various types of lighting, including LED, and offers flexible configuration options, adapting to the individual needs of the user.

Functionality and application

The AS-225D controller allows you to create a "follow-me" light effect on the stairs, which increases comfort and safety. The ability to connect controllers in series allows you to expand the system and control a larger number of lighting circuits. The device works with various types of activators – doorbell buttons, motion sensors, optical barriers or pressure sensors – which provides convenience and flexibility in use. Additional functions, such as permanent light switching or lock-out (e.g. from a brightness sensor signal), expand the possibilities of using the controller.

Construction features and parameters

The AS-225D controller is characterized by a compact design for mounting on a DIN rail (35 mm) or in a flush-mounted box (diameter 60 mm). The device is powered by a voltage range of 9-30 V DC, and each channel can handle a current of up to 4 A. A built-in thermal protection protects the device from overheating. The standby power consumption is 1 W, and during operation – 4 W. The device operates at a temperature of -15°C to +50°C and has an IP20 protection class. Screw terminals with a cross-section of 2.5 mm² ensure safe and durable wire connections. The tightening torque is 0.4 Nm.

The AS-225D controller offers a supply voltage in the range of 9 to 30 V DC and supports up to 12 channels. The maximum load current per channel is 4 A, giving a total system load of up to 24 A. Mounting is possible on a DIN rail with a width of 35 mm or in a flush-mounted box with a diameter of 60 mm. The device has an IP20 protection class and operates at a temperature of -15°C to +50°C, consuming 1 W in standby mode and 4 W during operation.

Advantages for installers and end users

For installers, the AS-225D controller means easy installation thanks to its compact size and intuitive parameter configuration. The ability to connect controllers in series simplifies the design of complex lighting systems. For end users, the advantage is increased safety and comfort when using the stairs thanks to the "follow-me" light effect and the ability to adjust settings to individual preferences. The "night light" function provides gentle lighting of the stairs at night, minimizing the risk of falling. The device is reliable and energy-saving, which translates into long-term savings. It should be remembered that the controller does not work with backlit buttons due to the low supply voltage.
