5WG1525-2AB23 RS 525/23 KNX Universal Dimmer 10-250VA 230V AP118 AP641 Room Box Module

The RS 525/23 is a single-channel universal dimmer designed as a modular device for installation within AP 118 automation module boxes or AP 641 room control boxes. As part of the room-side module family, which includes switching, blind, and heating actuators, this dimmer enables precise room function customization. The dimming output supports 10 to 250 VA and automatically adapts phase control to the load type, while integrated bus coupling ensures module independence from room controller electronics.

• Protocol: KNX dimmer module with integrated bus coupling unit; bus connection via terminal block with bus-powered electronics
• Output: Single dimming output for resistive, inductive, or capacitive loads (10-250 VA at +35°C ambient); 230V AC operating voltage; 50-60 Hz frequency; 1A rated current
• Dimming Principle: Automatic leading-edge or trailing-edge phase control adaptation; electronic protection against overload, short circuit, and temperature rise; IP 20 protection rating
• Installation: Modular design for AP 118 or AP 641 boxes (sold separately); dimensions: 50.2 × 48.8 × 35.5 mm (single slot occupancy)
• Terminals: Screwless terminals accept 0.5-2.5 mm² conductors; through-wiring capability for mains feed looping
• Operating Modes: Normal, one-level, two-level timer, and blinking modes; adjustable on/off delays; separate dimming time adjustment (0-100%) for switching and relative dimming
• Value & Status Handling: Definable switch-on brightness; immediate or soft dimming transitions; optional status objects; configurable responses to voltage events
• Comfort & Energy Functions: Night mode with adjustable period; pre-switch-off warning; 8-bit scene control (8 scenes); operating-hour and load-cycle counters with monitoring

Ideal for room-scale dimming within room control boxes, this module serves diverse environments including hotel guest rooms and suites, office spaces, serviced apartments, clinical and laboratory settings, and premium residential projects utilizing room automation box concepts. The integrated design minimizes cable runs to luminaires and simplifies future modifications through module replacement rather than extensive rewiring.
