    Voltage Input:     100 ~ 132 (or 240) VAC

    Current Output:  1A or 2A depending on unit/options

    Polarization:     Positive Center

    Output Conn.:     12V unit - Locking Barrel Plug, 2.1mm I.D. x 5.5mm O.D. x 9.5mm

            5V unit - Locking Barrel Plug, 2.5mm I.D. x 5.5mm O.D. x 9.5mm

  • 3 or 5 pin XLR or Ethercon connectors - 1, 2, or 3 Universes per EtherCon (See: EtherCon Pinouts) 
  • Mounting flanges - allows the unit to be counter top, under counter, or wall mounted


    • Ground Drive: a higher current drive that can be used to drive SSRs (solid state relays) or LEDs. The connected equipment can use the 12 volt unit output or an external power supply can be used up to 30VDC
    • 3.4V Control Voltage: is a set voltage with up to 5mA per output, providing a control voltage only for PWM controlled drivers such as PWM LED Drivers

    The DPM8 is a next generation new design DMX to 8 channel PWM (Pulse Width Modulation) controller driver with a wide range of tunable frequencies that can be user programmed. Need PWM to vary the frequency of LED's to eliminate TV strobing? The DPM8 will allow up to 4 different frequencies to be tuned (2 independent PWM outputs per frequency). The standard frequency range is from 123hz - 31.25Khz or in the Hi Speed option the range is tunable from 980hz to 250Khz. Each ground drive output can drive up to 150mA at 12VDC (30VDC Max). Designed to control SSR (Solid State Relays) that could then directly power high power LED fixtures, or any PWM circuits that need DMX to PWM control. OR 

    choose the positive control voltage version that can provide a low current control voltage output. 


    • 4 programmable tunable frequency settings
    • 8 Independent outputs
    • Choose either ground drive OR control voltage functionality
    • Programmable stand alone (no DMX) outputs
    • Compatible with all ELM Video Technology's DMX products
    • Drive solid state relays or any PWM controlled input
    • LED indicators for: Power, Data/Status, and 8 Outputs
