5WG1525-2AB03 UP 525/03 KNX Universal Dimmer 250VA 230V Mounting Frame BTI Interface

The UP 525/03 is a flush-mounted universal dimmer in the pocket-sized range, supplied complete with its mounting frame and BTI interface. This integrated solution eliminates the need for separate carriers or adapters, making it ideal for projects requiring local dimmers behind standard wall plates in guest rooms, offices, or apartments. The device draws power from the KNX bus and automatically adapts to connected loads when installed in 60 mm outlets.

• Protocol and Power: KNX dimmer with integrated bus coupling unit; bus connection through KNX bus terminal; electronics supplied by bus line at SELV level
• Output: One dimming output for switching and dimming resistive, inductive, and capacitive loads; rated power 10 to 250 VA at ambient temperature of +35°C
• Dimming Method: Automatic adaptation to trailing-edge or leading-edge phase control based on connected load; no lamp type declaration required during engineering
• Mains Data: Rated operational voltage AC 230 V; rated frequency 50 to 60 Hz; electronic protection against overload, short circuit, and temperature rise with fault reporting over bus
• Installation: For insertion into flush-mounting switch/socket box of 60 mm diameter and 60 mm depth; screwless terminals for 0.5 to 2.5 mm² conductors; includes mounting frame and BTI interface; housing dimensions 71 × 71 × 42 mm
• Operating Modes: Selectable normal mode, one-level and two-level timer mode, blinking; adjustable on/off delay; separate dimming time adjustment from 0 to 100%
• Value Handling: Definable switch-on brightness; immediate jump or soft transition to new dimming values; brighter/darker commands; status objects for switching state and dimming value
• Failure Behavior: Adjustable dimming values for bus voltage failure/recovery and mains voltage recovery; night mode for time-limited switching; warning before switch-off
• Advanced Features: Integrated 8-bit scene control for up to 8 scenes; operating-hour and load-cycle counters with threshold monitoring

This universal dimmer is ideally suited for local lighting control in hotel guest rooms and suites, apartments, single offices, medical consulting rooms, museum side rooms, and restaurants where dimmers must be installed behind existing button plates. The inclusion of mounting frame and BTI interface makes it particularly convenient for projects with multiple identical rooms. Built-in timer, night mode, and scene functions enable autonomous operation of corridors or bathrooms without requiring additional controllers.
