FEATURES
Remote Dimmer Module
The Remote Dimmer Module (RDMBC) provides remote control dimming for 010-VDC ballast in response to the phase control output of another dimming
device. The RDMBC iscontrolled independently from the controlling device
(120 VDC only), and powered (separately if needed) making it ideal for expanding dimming capacity or mixing lamp voltages on a single system.
• Works with 0-10VDC electronic ballasts
• Low-end trim available for setting the minimum brightness level
• Rated for use in return air plenums
• Electronic soft start of lamps
• Integral air gap relay
• LED indicators for line and control power
• NEMA 1 enclosure
•

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: Suitable for O-10VDC electronic dimming ballast
• 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 227V
• 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.
• Soft Start: Protects cold tungsten filament from inrush current.
• Indicators: Separate LED for input power and control power.
• Termination: Pigtails provided for contractor connections.
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.
