Mean Well KAA-4R4V-10S KNX/DALI 4-kanavainen himmenninmoduuli

The KAA-4R4V-10S bridges KNX TP1 and DALI, controlling four independent DALI channels with up to ten slaves each. Unlike single-protocol dimmers, it combines a KNX bus interface with a 100-240V AC auxiliary supply and 16V DC DALI output, enabling group, scene, and broadcast dimming from 0-100% without additional gateways.

Highlights

• 4 independent DALI channels, max. 10 DALI slaves per channel
• Supports 16 groups and 16 scenes per channel
• KNX TP1 input, DALI output per IEC 62386
• DIN rail mounting, 4 module width
• Configuration via ETS software

In daily use

Mount the actuator on a DIN rail and connect the KNX bus and DALI lines. The auxiliary power input accepts 100-240V AC, while the DALI outputs deliver 16V DC at up to 250mA per channel. Use ETS to assign individual, group, scene, or broadcast addresses. The operating temperature range is -20 to +50°C.
