Brief Introduction

KAA-4R4V-S

The KAA - 4RV - S dimming actuator has 4 independent channels built - in, and each channel output uses high - quality bistable (locked) relays, which is suitable for matching with various LED driver power supplies of MEAN WELL brand. The product specifications clearly indicate the maximum recommended number of LED driver power supplies for each channel, facilitating system designers to configure and plan LED luminaires for building projects. Based on the KNX architecture, KNX system engineers can easily perform programming and configuration according to users' needs or system specifications when planning and using the system. The KAA - 4RV - S dimming actuator has 4 green LED indicators on its front - panel buttons to show the on/off status. With a miniaturized module design of only 4SU (72mm) in width, it greatly reduces the installation space requirements and can be quickly installed on a 35mm standard rail. This device is connected to the KNX bus through dedicated bus connection terminals. The new version meets the KNX regulation "KNX Data Secure". "KNX Data Secure" can prevent building automation from being remotely manipulated and can be enabled and configured in ETS. Each channel of this product has a built - in "KNX Dimming Curve 0(1)" - 10V digital dimming control function, and the dimming curve can be selected as linear or logarithmic, providing users with an excellent dimming experience. Similarly, it is also very suitable for matching with various motion sensors in building control applications to achieve full - function control. This dimming actuator is powered by the EIB/KNX bus, without the need for additional power supply, and has multiple functions and high reliability, which can meet the current needs of modern building design in various aspects.
