dali dimming switch are different from thyristor dimmers and 0-10v led dimmer and cannot be mixed. DALI system will be equipped with bus power when wiring, (bus power can be added to the bus alone, or it may be that the DALI system has built-in bus power, no need to add on the line), so how many dali dimmer 220v can be equipped on the DALI line , How many DALI power supplies, there will be bus line loss, these all depend on the DALI bus power supply.

The DALI wire power supply will provide enough current to support the DALI dimmer on the bus, the DALI power supply and the line loss of the bus. Therefore, the DALI dimmer of the DALI system has no load limit.

But at present, almost all DALI projects, if they are large-scale projects, will be separated into main control and main control.

The main control wiring control is composed of a main control system (usually with built-in bus power) + several DALI dimmers + several DALI power supply. This kind of master control DALI dimming is generally suitable for local lighting control (such as a certain floor or a certain area). The line will not be stretched too long, and the dimmer and dimming power supply will not be too much. The controlled bus power supply can provide enough current for the dimmer on the main line, DALI power supply and the line loss of the main line. (The main control can be regarded as a small DALI system, which can be controlled by buttons on the main control module or the part of the light controlled by software) So if a building uses DALI system to control the lights, there will be Many masters control local lights.

Finally, all main control systems are also connected to the main line of the main control, and the main control will uniformly control the lighting of the entire building

Therefore, the DALI dimming system is a very powerful lighting control system, which is often used in large buildings, and the consumption of dali dimmer 220v and DALI power supply are large.
