High amperage applications are easily controlled with our "FD" modular systems which incorporate a unique wall mounted, Eclipsis Series, single-point-of-control preset slide unit, with a remote mounted FD power module for controlling up to several hundred T8, T5 or CFL lamps.

In addition, HUNT manufacturers products compatible with the new digital DALI (Digital Addressable Lighting Interface) protocol.

Typical Uses and Applications

Dimming electronic fluorescent ballasts can be accomplished through either 0-10 VDC or Phase-Control analog technologies, or the new digital DALI protocol. Any of these can be used in most dimming situations, but each has its own unique benefits.

Today, the most commonly used technologies are analog. Typically, if the application is energy-management in nature, 0-10 VDC is more likely to be used. This scenario allows the user to tie the lighting together with occupancy or daylight sensors, building management systems or manual dimming controls.

If the applications is part of an architectural lighting scheme, such as dimming a conference room or an individual office, Phase-Control technology may be most appropriate. Here, the stand-alone dimming ballast with only a two wire connection allows for simple, cost-effective retrofits and excellent single location control.

The newest technology, digital DALI, is best suited where a higher degree of individual lamp addressibility is required or the flexibility to easily provide for future lighting changes is desired.

If you have questions about which ballast technology might be best for your particular application, please contact the factory for engineering assistance.

Critical Differences

It is important to understand that not all ballasts are approved to work with HUNT's electronic fluorescent dimmers. Compatible ballasts by technology include:
	0-10 VDC	Phase-Control	DALI
	Advance Mark VII ballasts OSRAM Sylvania dimming ballasts Prescolite Intelect ballasts ESI SuperDim ballasts Universal/Magnetek Ballastar ballasts Motorola Helios ballasts GE Dimming ballasts	Advance Mark X ballasts Philips EcoTron Lutron Tu-Wire ballasts	Advance DALI ballasts OSRAM DALI ballasts Tridonic Excel ballasts
	Note: As they become approved, additional ballasts from different manufacturers are being added to this list. Please contact the factory for updated information.

Caution

The three ballast technologies used in electronic fluorescent dimming (0-10 VDC, Phase-Control and DALI) ARE NOT COMPATIBLE!

• 0-10 VDC ballasts utilize a total of four (4) wires. Two low-voltage leads are for ballast control and two line voltage leads wires are for ON/OFF power control.
• Phase-Control ballasts use the same two (2) wires to power the ballast and to control the light level.
• DALI ballasts utilize a special wiring configuration that typically requires only a single set of shielded, twisted-pair, low-voltage wire.

It is critical that the dimmer and ballast be properly matched to each other... or the dimmer and ballast will not function properly... and component damage may result. If you have any application questions or concerns, please contact the factory for assistance before purchasing your electronic fluorescent dimming system components.
