Universal Dimmer DIM02SA/500U - Qbus

The DIM02SA/500U can dim up to 2 circuits of each 10-500VA and can handle halogen spots, electronic & magnetic transfo's, incandescent lamps, dimmable CFL's and 230V LEDs. The Universal Dimmer DIM02SA/500U from Qbus has an internal protection against short circuits, overload and overheating and has a built-in CRC-filter. This module can also be used Stand-Alone (without Qbus Controller) as it contains 3 inputs to connect standard pushbuttons (including All Off and Panic button).

The DIM02SA/500U module also has 3 potential-free inputs to connect standard push buttons. Input 1 to 2 control respectively output 1 to 2, input 3 (A) is a scene input which executes an ALL-OFF-scene when pushing for 0,7 seconds (and then releasing the button), or a panic-scene (all outputs on) when pushing the button for 3 seconds. The inputs are set standard in push button mode. When the module is connected to a controller, the input mode of the DIM02SA/500U can be changed to Normal Open, Normal Closed or toggle.

The dimmer outputs can only be used as a one-button dimmer. As a one-button dimmer the dimming cycle must always be completed: starting from zero to maximum and back to zero. A short pulse (< 0,3 sec.) will take the dimmer to zero or to the maximum value in 2,5 sec.
