Bộ điều khiển Ballasts - 472 1–10 V / DSI Converter

472 1–10 V / DSI Converter


472 DIGIDIM 1–10 V & DSI® Converter

 The DIGIDIM 1–10 V & DSI® Converter has been designed to control electronic ballasts that comply with IEC 60929 and ballasts that comply with the DSI® standards. This ensures that DIGIDIM systems are compatible with, and easily integrated into, existing systems.

The Converter can switch a maximum of 15 Helvar electronic ballasts/drivers.

The analogue 1–10 V signal and the digital DSI® signal can control 50 electronic ballasts.          

 Key Features

  • Out-of-box operation provides control using DALI standard broadcast commands.
  • For 1–10 V control, the Converter can switch a maximum of 15 ballasts/drivers. An external contactor should be used for more ballasts.
  • Converter complies with DSI® 1 and DSI® 2 standards.
  • Default light output at initial power up is 100 %.
  • Universal supply voltage operation.
  • DIN-rail mounted and only 70 mm wide.
  • Easy programming by using the group selection switch.


Additional Functions

  • Controller status report.
  • System failure level/Ignore.
  • Power on to last level.
  • Sink or source mode.
  • /Min. levels, Fade times*, Scenes* and Groups*.


* These functions are programmable using a Helvar infrared remote control.
