Doug Fleenor Designs DMX12DIM-ELV-JBOX Data Sheet

Wall Mounted, Low Power, 12 Channel, ELV DMX512 Dimmer

model: DMX12DIM ELV-JBOX

technical data sheet

The DMX12DIM ELV-JBOX is a twelve output dimmer designed for high efficacy
loads, and minimal losses. This dimmer uses “reverse phase” (aka: “trailing

edge”) dimming techniques and MOSFET power devices. This type of control is

required for proper dimming of many LED fixtures. Each output can drive loads
up to 100 Watts. Each channel may be configured for reverse phase dimming
(default), forward phase dimming, or non-dim operation.

The dimmer is a wall mounted unit. All connections are made by terminal blocks
for easy contractor installation. The NEMA1 electrical enclosure is provided with
standard conduit knockouts on two surfaces.

The DMX12DIM ELV-JBOX is ETL Listed to the UL508 standard.

SPECIFICATIONS: All specifications meet or exceed DMX512 requirements.

Input circuit: Protected EIA-485 receiver (LT1785)

Input protection: Undamaged by up to 60 Volts continuous, 15KV transients
Input signal: 0.2 volts minimum, DMX512, DMX512/1990, or DMX512-A
Input/thru connector: One 3 position terminal block

Termination: None, a 120 Ohm termination resistor is required if the dimmer is the last device on the

line
Power input: 120 VAC 60 Hz 10 Amps at full load, actual current draw is 0.07A plus connected load
Power input connector: 3 position terminal block (Line, Neutral, Ground) suitable for up to #12 AWG wire
Idle power: 7 Watts
Power output: 120 VAC 60 Hz 0.83 Amps (100W) maximum per output
Minimum load: No minimum load requirement
Output protection: 1.5A internal fuse on each output channel
Output connectors: 2 position terminal block (Line, Neutral) on each output suitable for up to #12 AWG wire
Dimming circuit: Digitally fired, optically-isolated, MOSFET power devices that allow for forward or reverse

phase dimmer control

SPECIFICATIONS: (Continued)

Rise/fall time: 2 uS (10% to 90% at 90 degree firing angle) at rated load
Dimming curve: Square law, visually appealing on LED lamps (120V), halogen lamps, magnetic low-

voltage (MLV) and electronic low-voltage (ELV)

Non-dim curve: Each channel can be configured as a non-dim which turns on at 60%, off at 40%
Outputs switch on at zero crossing. Other non-dim trip point options include 50% and 1%

(globally settable).

DMX footprint: Twelve consecutive DMX slots beginning with the selected DMX starting address
DMX starting address: Three digit front panel thumbwheel switch, address changes are immediate (no power

cycling required)

Local control: An “address switch” setting of 601 turns on output 1, 602 turns on output 2, etc. A setting

of 699 turns on all outputs. A setting of 698 turns on all outputs when DMX is present. A

setting of 697 turns on all outputs if any DMX level is above zero.

Status indicators: Red POWER indicator
Green MIMIC 1 indicator mimics the intensity of output 1 (useful in troubleshooting)

Green SIGNAL indicator illuminates when DMX512 is present, flashes when local control

is active (address switch settings of 601 thru 612 and 697 thru 699)

Cooling: Convection cooling, no fan required
Isolation: DMX512 input is optically isolated from AC power circuits to 600 Volts
Color: Gray
Safety listing: ETL Listed to UL 508
Size and weight: 18" high x 12” wide x 4" deep, 10 pounds
Warranty: Five years parts and labor. Dimmer must be returned to Doug Fleenor Design for

warranty repair. Shipping to Doug Fleenor Design is to be paid by the customer. Return

ground freight is paid by Doug Fleenor Design. Warranty covers manufacturing defects.
