Meanwell KAA-4R4V-S is a 4-channel dimming actuator equipped with high-quality independent latching relays for switching control, compatible with various Meanwell LED drivers. The product specifications indicate the maximum recommended number of LED drivers per channel, facilitating building planning. Based on the KNX architecture, KNX system engineers may programme it as required during planning or operation via ETS software, or manually control it using physical panel buttons. Each channel features an independently configurable green LED indicator to display switch status.
Beyond basic switching functionality, this actuator provides a DC 0(1)-10V current sink interface for dimming connected LED drivers or ballasts. The dimming curve is adjustable between linear and logarithmic modes, delivering an enhanced dimming experience for end-users. It can also be integrated with motion sensors within buildings to conserve energy. Powered via the EIB/KNX bus without requiring an additional power supply, it offers reliability and versatility to meet diverse requirements in modern buildings. This makes it widely applicable in building automation, lighting switch/dimming control, and blind/curtain control applications.
