FEATURES
The Remote Dimmer Module (RDMI) provides remote control dimming and
switching for a variety of lamp sources in response to the phase control output of another dimming device. The RDMI is powered independently from the
controlling device, making it ideal for expanding dimming capacity or mixing
lamp voltages on a single system.
• Dimmer controls incandescent, magnetic low voltage, halogen and neon/cold cathode lighting
• 1920 watt capacity at 120 volts
• Mounts to standard 4" J-box
• Electronic soft start of lamps
• LED indicators for line and control power
• Convection cooled
• Square law dimming

SPECIFICATIONS
FUNCTIONAL
• Provides dimming of up to one full circuit of lighting in response to a control
signal from the output of a compatible dimmer channel.
• Dimmer: Universal type, suitable for incandescent, magnetic low voltage,
neon, cold cathode and tungsten halogen sources.
• Control Input: Dimmed output (phase control) from a SQIDC or ISD I dimmer.
• Output: Linear with respect to control input within 10%.
ELECTRICAL
• Dimmer Capacity:
1920VA at 120V incandescent, tungsten halogen;
1920VA at 120V neon, cold cathode and magnetic low voltage dimming ballasts;
• Input Power: May be a separate branch circuit or shared with the controlling
dimmer circuit.
• Phasing: No phase relationship required between RDM and the controlling
dimmer.
• Relay: Air gap for positive on/off operation.
• Indicators: Separate LED for input power and control power.
• Termination: Terminal Blocks
MECHANICAL
• Enclosure: NEMA 1; CRS with extruded aluminum heat sink; rated for use in
return air plenum.
• Mounting: Any orientation; replace cover on standard 4" J-box.
