 93-606-62  REV: A 
The RDM-3DC Triple DC Module (FG606-62) is a 1920 W module used for the 
dimming of fluorescent ballast loads. It uses a 0 to 10 VDC current sinking for 
use with four-wire ballasts. It is designed for use with the  RDA series of 
enclosures, in an AMX Lighting™ modular digital dimming system. The module’s 
120 and 277 VAC ratings are CE, UL, and C-UL approved.  
RDM-3DC UL and C-UL Ratings
• 120 VAC, 50/60 Hz, 1920 W
• 277 VAC, 50/60 Hz, 1920 W
• Control Out: 50 mA, 12 VDC sinking
Suggested Dimmed Loads
• Four-wire dimmable ballasts, like Advance Transformer Mark VII™ or the 
Energy Savings SuperDim™ series
Specifications
• Dimensions (HW): 10" x 2.75" (25.4 cm x 6.99 cm)
• Non-phase dependant
• Use wires rated at 75°C (167°F)
• Torque terminals to 20 in-lbs. (2.3 N/M)
• Max. wire size: 10 AWG (4 mm²)

Caution: Pre-Installation Notes
• All Class 1 wiring must be connected to proper terminals.
• All control wiring must be connected to proper terminals.
• Disconnect power while installing or connecting the unit.
• Keep top and bottom air vents clear at all times.
• Use low-voltage wires with a 300 volt rating or greater.
• Use field installed copper conductors.
• All electrical ratings are for continuous duty.
• For indoor use only.
• Test loads for shorts before connecting.
• This module may require extra power from the AXlink connection or an 
external power supply connected to the control card.

The fuses protect the dimming 
circuit from a low impedance load.
• The fuse will blow if it were 
incorrectly wired
• Catastrophic ballast failure
• Reversing switched and
dimmed circuits
• Reversing dimmed and
line circuits.
The dimmed output must be
connected to a high impedance 
load.
