Compatible Ballast Information
This section contains descriptions and manufacturer information on AC-controlled magnetic
ballasts, AC-controlled electronic ballasts, DC-controlled electronic ballasts, and ballast interfaces
that are compatible with the AMX Lighting Control System.
AC-Controlled Magnetic Ballasts
AC-controlled magnetic ballasts are simple circuits that smooth out the raw AC power to lamps.
They should not be used in presentation dimming applications because they do not perform well in
lower dimming ranges.
AC-Controlled Electronic Ballasts (3-Wire Ballasts)
AC-controlled electronic ballasts deliver smooth flicker-free operation down to 1% brightness at
low light levels for some models (under ideal conditions). The ballast receives an AC dimming
signal and interprets the appropriate response to the lamps. AMX Lighting can control AC-style
ballasts using the RDM-FDB satellite module. The following table lists compatible AC-controlled
electronic ballasts.
DC-Controlled Electronic Ballasts (4-Wire Ballasts)
The DC-controlled Electronic Ballasts track a 0-10 or 0-12 VDC channel for dimming and an AC
switch channel for on/off. This ballast design is better than magnetic, but many stop dimming at
about 20% brightness. That's fine for energy management and secondary lighting zones, but not for
primary lighting that requires precision, low-level dimming control. The following table lists
compatible DC-controlled electronic ballasts.
The ballasts listed in this section have been reported to AMX by other parties to be
compatible with AMX Lighting dimming systems. AMX has not tested every ballast/
dimmer combination, and cannot verify either compatibility or correct operation. AMX
does not specifically recommend any particular ballast make or model. Contact AMX
for information regarding ballasts not listed.
AC-controlled magnetic ballasts are not recommended for critical lighting control.
