ABB STD-500U :: Universal Power Dimmer - 500 W


  • Product Description
  • Technical information

    • Type
    • Power dimmer

The universal power dimmer is used for dimming loads up to 500 VA. Using extensions from the universal power dimmer system, loads of up to 3 kVA can be dimmed directly via a load line. Connecting multiple universal power dimmers in parallel enables the synchronous dimming of lighting systems of up to 54 kVA. Permitted loads include light bulbs, 230 V halogen lamps and low-voltage halogen lamps with conventional transformers or Busch electronic transformers. Loads are detected automatically; leading edge or trailing edge phase control is selected as the operating mode accordingly. Conventional and electronic transformers cannot be used together on a single device.

Integration into EIB / KNX systems is performed via the EIB / KNX controller with the PWM input.
