The DMX8DIM is an eight output 'green' dimmer designed for minimal losses, low idle power (less than 1Watt), and low maintenance (no fans or air filters). Housed in a 12" x 12" x 4" NEMA Type 1 enclosure, the electronics are removable until drywall is complete. The electronics are then reinstalled using only four screws. Wiring is by compression type screw terminal blocks.

Features includeRated at 240 Watts per output, the dimmer has self resetting overload protection and is powered by a single 20A branch circuit.

The DMX8DIM is DMX512-A compliant and ETL listed to UL508.

Doug Fleenor Designs 8 Channel DMX Dimmer Features:

  • Local control for load testing
  • Dim/non-dim per output
  • Toroidal filtering
  • 16 Amp 120V input
  • Eight 2 Amp outputs
  • Troubleshooting LED
  • Optically isolated DMX input
  • Operates high efficacy loads (LED, CFL, and Neon)
  • Operates capacitive loads (electronic low voltage andlong cable runs)
  • Operates inductive loads (magnetic low voltage and ceiling fans)

Doug Fleenor Designs 8 Channel DMX Dimmer Specifications:

  • Input circuit: Protected EIA-485 receiver (LT1785).Transient protected to 15 KV, Continuous to 60 V.
  • Input signal: 0.2 volts minimum, 12 volts maximum,DMX512, DMX512/1990, or DMX512-A.
  • Signal Connectors: Phoenix Contact Combi-Con Pluggableterminal blocks. Two provided: In and Through.
  • Termination: Removable 120 Ohm termination provided onfeed through.
  • Power Input: 120 VAC 60 Hz 16 Amps at full load (Uses20 Amp branch circuit at 80% capacity. Actual current draw is connected loadplus 50 mA (max).
  • Idle Power: Less than 1 Watt.
  • Input Power Connector: Three position screw terminalblock accepts up to 12 AWG solid or stranded wire (Line, Neutral, Ground).
  • Power Output: 120 VAC 60 Hz 2 Amps per output.
  • Output Protection: 2 Amp self resetting over currentdevice on output, 100 Ohm PTC thermistor on driver.
  • Output Connectors: One three position screw terminalblock per output accepts up to 12 AWG solid or stranded wire (Line, Neutral,Ground).
  • Dimming Circuit: Digitally fired, phase controlled 16Amp snubberless triac (Alternistor) with high dv/dt driver. Triacs arescrewdriver replaceable. One spare triac provided. A leakage control circuiton each output prevents ghosting of moderate loads.
  • Rise Time: 12 uS (10% to 90% at 90 degree firingangle) at rated load.
  • Dimming Curve: Square law. Visually appealing on LEDlamps (120V), halogen lamps, magnetic lowvoltage (MLV) and electroniclow-voltage (ELV).
  • Non-dim Curve: Outputs set to non-dim turn on at 60%,off at 40%. Outputs switch at zero crossing.
  • DMX Footprint: Eight consecutive DMX slots beginningwith the selected DMX Starting Address.
  • DMX Starting Address: Nine position internal DIPswitch. Must be set at time of install. Not user accessible.
  • Non Dim Switch: Nine position internal DIP switch. Oneswitch per output plus ‘local’. Not user accessible.
  • Local Control Switch: When local switch is ON, Non-dimswitches function as on/off switches for load testing.
  • Chase Mode: Factory programmable chase sequence(default is 8-step chase 1/8 seconds per step).
  • Status Indicators: One multi function LED: Blinking Red: power with nosignal.
      -  Solid Red: local control switch on.
     -  Blinking Green: DMX control signal present.
      -  Solid Green:Output 1 on.
  • Cooling: Maintenance free convection with front panelventilation. No fan.
  • Isolation: Double isolated: DMX512 input is isolatedfrom control electronics to 1500 Volts. Control electronics are isolated fromAC power circuits to 600 Volts.
  • Color: Gray rear and sides, Green front.
