Bộ DIMMER Helvar - DIGIDIM 500 W Thyristor Dimmer (455)

 

 DIGIDIM 500 W Thyristor Dimmer (455)

 

 

 The DIGIDIM 500 W Thyristor Dimmer (leading edge) is a DALI-compatible lamp interface unit for use in a DIGIDIM lighting control system.

The dimmer is a DIN-rail mounted unit that can control a maximum load of 500 W. It can be connected to mains voltage lamps directly, or to low voltage lamps via a wire-wound transformer. The dimmer is provided with a status LED and a physical selection switch.

The LED provides status and fault indications, the physical selection switch is used to identify the device during system configuration.

Note: This unit does not contain a DALI power supply. Therefore, one must be incorporated elsewhere in the system.

 

 

 Key Features

  • Out-of-box operation. No programming required when using DIGIDIM slider, rotary or push button panels.
  • Input voltage and frequency fluctuation compensation ensures stable output levels with fluctuating incoming mains levels.
  • Over current and over temperature protection.
  • DIN-rail mounted and only 35 mm wide.

 

Additional Functions

The following functions may be programmed using the DIGIDIM Toolbox software:

  • Maximum/minimum levels, fade times*, scenes* and groups*
  • Dimmer status report
  • System failure level/ignore
  • Power on level
  • Power on to last level

 

* These functions are also programmable using a Helvar infrared remote handset.
