DMX


Question: Could you please introduce more about Phase-cutting dimming?

Answer:

Forward Phase Control

Use thyristor as a switching device

Cost-effective

Reverse Phase Control

Use MOSFET as a switching device

Good compatibility

Question: How to choose the right LED dimmable drivers?

Answer:

1. Inrush current

Large inrush current, bad for dimmer;

Small inrush current, the more lights.

2. PF(Power Factor)

High power factor makes the device more efficient.

3. EMI(Electromagnetic Interface)

Strong EMI may cause malfunction or even damage of electronic equipment.

Mixed Systems of DALI & DALI-2
Questions Answers
Is it OK to use DALI-2 control gear in DALI version-1 systems? No problem. DALI-2 is designed for backward compatibility.
Is it OK to use DALI version-1 control gear with DALI-2 application controllers? No problem. But the DALI version-1 control gear with not have the new DALI-2 features.
Is it OK to use bus power supplies that are not DALI-2 certified? There is no standard specification and tests for bus power supplies before DALI-2.
