The Vivo VOS KNX dimming actuator is an KNX rail mounting modular device for independent switching and dimming of 2 groups of lighting devices (CFL,
RLC and LED). The device is equipped with an integrated bus communication module and is designed for rail mounting in PDUs. To operate, the device
receives a telegram from the bus, sent by a KNX device (such as a button, a sensor or another switching or control device), which controls the opening or
closing of the corresponding relay or dimming of the light intensity emitted by the lamp of the connected lighting device. The device also allows manual
switching/ dimming of an output channel with the buttons on the front of the device. The device is powered by the KNX bus line with 30 Vdc SELV voltage
and requires auxiliary power supply at 110-230 Vac.
