The EAE UD106 KNX Universal Dimmer Actuator provides phase dimming control for up to six independent channels at 300 VA per channel. It is designed for incandescent, halogen, and phase-dimmable LED loads where trailing- or leading-edge control is required — complementing the 1–10 V approach of the SD110.

Each channel is programmed in ETS5 and can be operated manually via push buttons on the enclosure. The UD106 includes comprehensive fault detection (short-circuit, over-current, over/under-voltage, over-heating, load error) and voltage measurement reported on the KNX bus. Three channel grouping options allow merging outputs for higher-power loads.

Key Features — 6 × 300 VA Phase Dimming

Dimming Outputs

• 6 channels: Independent phase-dimming outputs.
• 300 VA per channel: Suitable for higher-power incandescent, halogen, and dimmable LED circuits.
• Phase dimming only: Leading/trailing edge — not 1–10 V or DALI.
• Channel grouping: 3 grouping features to merge outputs for higher VA loads.
• Manual control: Push buttons on the device enclosure for testing and override.

Monitoring and Safety

• Error detection: Load error, short-circuit, over-current, over-voltage, under-voltage, over-heating.
• Voltage measurement: Mains voltage reported on KNX.
• Recovery behaviour: Configurable state after bus voltage failure and return via ETS.
• Feature priority: Channel functions processed according to ETS-defined priority order.

Per-Channel Functions (ETS)

• Staircase lighting: Timed auto-off.
• Scene function: Integration into KNX lighting scenes.
• Forced operation: Override mode with priority over other functions.
• Channel grouping: Merge outputs for higher-power circuits.

Applications and KNX Integration

• Residential and hospitality: Phase-dim incandescent, halogen, or dimmable LED circuits from KNX switches and sensors.
• High-power circuits: Channel grouping merges outputs when a single channel's 300 VA is insufficient.
• Maintenance diagnostics: Fault and voltage feedback on KNX for remote monitoring.
• 1–10 V alternative: For analogue dimming of fluorescent/LED drivers, use the EAE SD110 1–10 V Dim Actuator.
• On/off switching: For non-dimmed circuits, use the EAE SW108 Switch Actuator.

Choosing EAE Dim Actuators

The UD106 is the phase-dimming choice with advanced fault detection and 300 VA channels. The SD110 suits 1–10 V gear with 10 channels and integrated 16 A relays. For DALI luminaires, use an EAE DA100 or DA110 DALI Gateway.
