4W+4W 24V Tunable White LED Spot Module

TILLUME Expert Series | Model 81061M04 | 2200K–6500K | 24V DC PWM

Document Datasheet Body
Version V1.0
Manufacturer TILLUME

Engineering summary: 81061M04 is a compact 24V constant-voltage tunable white LED spot module with separate warm-white and cool-white PWM channels. The final LED-side output, not only the upstream KNX/DALI/Loxone protocol, must match the channel count, load capacity, PWM behaviour, voltage drop and controller configuration.

4. Planning Notes for KNX / DALI / Loxone Systems

PWM output

Use a final 24V PWM output. The protocol side may be KNX, DALI or Loxone, but the LED-side electrical output is the compatibility point.

PWM frequency

For most projects, plan around 1–4kHz where controller behaviour and EMC conditions are suitable.

Power reserve

Check total load, per-channel load and approximately 20% power-supply reserve for the complete lighting zone.

Controller mode

Different modes such as max brightness and constant output brightness can change practical output behaviour.
