Description

The KAA-4R4V-S dimming actuator is a 4 channels device with high quality independent latching relay to
turn on or off ,which is suitable for MEANWELL all kinds of LED drivers. The product specification indicate
the maximum number of recommended LED drivers per channel which is easy for building planning.Based
on the KNX architecture, KNX system engineers can easily program through the ETS systemas needed
during planning or use, or manually through the physical buttons on the panel. KAA-4R4V-S is independently
configured with a green LED on each channels to indicate the status of the switch. The compact design
with 4 units(72mm) wide modular makes it suitable for installation in the distributionboard on 35mm
mounting rails in the EIB/KNX application. The connection to the KNX bus is implemented via a bus
connection terminal. The new version also supports KNX Data Secure function. KNX Data Secure offers
protection against manipulation in building automation and can be configured in the ETS project.In
addition to the basic switch function, a DC 0(1)-10V interface by current sinking is provided for dimming
the connected LED driver or ballast. The dimming curve can be adjusted to linear or logarithmic mode,
so that the end user has excellent dimming experience. It can also be used with motion sensors in the
buildings to save energy. The dimmer are powered viathe EIB/KNX and do not require any additional
power supply. As result, KAA-4R4V-S is featuring both reliability and multi functionality to meet various
needs in a modern building.
