Lighting control for perfect spaces

The new switch/dim actuator is used

anywhere complex DALI light control

systems need to be operated energy-

efficiently and with low maintenance

costs. The new device has a multitude

of functions to increase comfort such

as the control of several electrical

ballasts.

With Tunable White and up to seven

adjustable dimming curves, lighting

can be adapted to any situation.

Moreover, the devices offer the option

of saving light scenarios, sending status

and error notifications, and counting

of switching cycles and operating

hours. Especially in combination with

presence detectors, which control

brightness fully automatically, the

new switch/dim actuators offer the

best foundation for optimal light

conditions in the room.

Individual light customization

with Tunable White

The new switch/dim actuator serves

as an interface between the KNX

installation and the DALI lighting

system. The device also supports

Tunable White, a variable and seam-

less color temperature control from

warm to cold white light.

Dynamic color temperatures do not

only favor a good atmosphere in the

room, but contribute to human well-

being. This follows the concept of

Human Centric Lighting, a way to

plan lighting based on human needs.

Whereas cold white light promotes

concentration, warm white light has

a calming effect. This way, the light

in a room can be positively adjusted

to individual demands and situations.

Adapted color temperature can ensure

perfect visual and working conditions,

which are indispensable especially

in educational facilities and offices.

Highlights

• Tunable White

• Higher light comfort due to

energy-saving switching and

dimming of up to 20 DALI ECGs

per channel in broadcast mode

• Optimal lighting for high comfort

thanks to adjustable dimming

• Easy installation and low

maintenance expenses
