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.
