Silvair CCT 2CH: WW/CW dual-channel LED control via Bluetooth Mesh

Advanced Tunable White management with NLC profiles, visual comfort and efficiency

Standard

The Silvair CCT 2-channel controllers and drivers enable wireless adjustment of correlated color temperature (CCT) and light intensity for dual-channel LED loads WW/CW (warm/cool) via Bluetooth Mesh (SIG) with Bluetooth NLC (Networked Lighting Control) profiles. Control is managed through the Silvair app (iOS/Android) and software, with full support for scenes, timers, profiles, automations and local/offline operation. Some Silvair devices can be configured via NFC. Versions are available with input 12/24/36/48 V DC and 110/220 VAC, with outputs in constant voltage (CV) or constant current (CC).

System architecture

• Silvair CCT 2CH: compact/in-wall modules for independent variation of WW/CW LED channels and dynamic white mixing (Tunable White).
• Compatible drivers: CV/CC versions with DC or AC input.
• Gateway: for remote access, time synchronization and cloud integrations; BACnet/BMS bridge for building automation.
• Wireless controls: Silvair mobile app, wall panels, battery-powered buttons or remotes.
• Silvair Push Button Coupler: enables traditional push-button use for local dimming and scene control.
• Sensors: occupancy and lux for automation; NLC subscription by third-party devices (e.g., HVAC/thermostats).
• Multiprotocol integration: through bridges/converters to interface existing networks/protocols (DALI, 0–10V, DMX).
• Mesh topology: routing between nodes with typical indoor coverage of ~10–30 m per hop.

Advanced features

• Precise dynamic white control: continuous mixing of warm/cool channels for any intermediate tone (Tunable White).
• Dim-to-Warm curves: warm fading simulating halogen sources (warmer light at lower brightness).
• Channel calibration: WW/CW balancing with configurable min/max limits and customizable power-on state.
• Security: authenticated provisioning, role/permission management and end-to-end mesh encryption.
• Fast pairing/commissioning: guided setup via app with automatic node, group/zone and profile detection.
• System modularity: easy expansion by adding drivers and control devices.
• Deep dimming <1%: smooth flicker-free CCT dimming (with quality drivers).
• Scenes and automations: schedules, fade, ramp, sunrise/sunset and sensor-based programs.
• Reliable network: BLE mesh with self-healing paths and local operation without data network.
• High-frequency PWM: typically 250–500 Hz (entry), 1–4 kHz (mid), 8–16 kHz (high-end), suitable for photo/video.
• OTA: firmware/parameter updates and backup/restore via app.
• NLC & HVAC integration: NLC profiles with occupancy/lux subscription for lighting + climate automation.
• BMS/BACnet: integration into Building Management Systems via dedicated gateway.
• Emergency lighting testing: support for automated periodic tests and reporting (where hardware-enabled).
• NFC programming: quick and customizable setup for compatible drivers/dimmers.
• Visual comfort & wellbeing: CCT adjustment supporting circadian rhythms; brightness adaptable for work, relaxation or accent lighting.
• Energy efficiency: optimized consumption, reduced thermal stress and extended LED lifespan.

Typical applications

• Circadian cycles: wellness-oriented clinics/spas, offices, medical practices and wellness centers with adaptive light.
• Smart residential: bedrooms, living rooms and kitchens with “activity/relax” scenes.
• Hospitality: hotels/B&Bs with customized scenes and simple local control.
• Retail: shop windows and corners with dynamic white for color rendering and atmosphere.
• Offices and studios: workstations and meeting rooms with dynamic CCT for comfort and productivity.
• Exhibitions: CCT modulation to enhance materials and artworks.
• Small/medium installations: wireless retrofit without proprietary bus; hybrid projects with BMS/DALI.

Available types

• Silvair CCT 2CH: two-channel control for warm/cool white LEDs via Silvair BLE/NLC protocol.
