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.
