RDM-HDC Heavy Duty DC Module
2400 W, 0-12 VDC
The RDM-HDC Heavy Duty DC Module is a heavy-duty 2400 W module for
dimming of fluorescent ballast loads. It uses a 0 to 12 VDC current sinking
or sourcing for use with all 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, 240, and 277 VAC ratings are CE, UL, and
C-UL approved.

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.
