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 adjust-

able dimming

• Easy installation and low

maintenance expenses

Lighting control for perfect spaces

The new switch/dim actuator is used any-

where 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 noti-

fications, and counting of switching cycles

and operating hours. Especially in combina-

tion 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

seamless 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.

The switch/dim actuator N 525D11

is a DALI-2 certified device.

It has successfully completed

the DALI-2 certification process

operated by DiiA, ensuring

even more the interoperability

to other certified devices.
