Diagnostics
Unique to interVOLT, is the self diagnosing electronics. This design provides valuable feedback to installers and operators alike. Twin LED’s display the system status and will indicate standby power, lamp load connected (lights on), over temperature and output short circuit.

Protection
interVOLT dimmers feature a host of devices designed to protect the electronics from various connection and application problems. The dimmers are protected against, short circuit, over temperature and an internal fuse protects the electronics in the event of component failure.

Memory
All interVOLT dimmers have an integrated device which stores data for various functions including the memory feature. The memory function records the current ‘brightness’ setting when the lights are switched off, so that same ‘brightness’ is resumed when turned on again. The DuoDim has the added advantage of memory retention upon power loss as well – truly unique!

Soft Starting
A special feature of interVOLT dimmers is the soft start function. High inrush current diminishes the life of common filament lamps. This feature controls the start up power by limiting the in-rush current, considerably extending the bulb life.

Safety
An innovative feature of our dimmers is the temperature failsafe mode. Most electronic dimmers either fail or shutdown on temperature overload. interVOLT dimmers are programmed to dim the lighting circuit to 50% of full load if the electronics should overheat.

Dual Channel
The DuoDim is a true two channel dimmer in that each channel is capable of controlling and monitoring two separate lighting circuits. In UNGROUP mode the total power output of the DuoDim is equally divided between the two channels. In GROUP mode the two channels can be combined and controlled with one switch only thereby using the total power of the whole dimmer as one. Thus the DuoDim is truly two dimmers in one!
