Product Description

Doug Fleenor Design LED300 Power Supply for Color Kinetics CB6/CB12 - 6 Outputs

The LED300 power supply distributes DMX512 data and 24 Volt power to lighting fixtures and accessories. Primarily designed to power and control Color Kinetics ColorBlast 12 LED fixtures, the LED300 can also drive Color Kinetics iColor Cove, Altman Spectra PAR, and similar products, as well as color scrollers, gobo rotators, and other powered DMX512 controlled accessories.

Power and data are provided on six 4-Pin female XLR connectors. Power appears on pins 1 and 4, Data is provided on pins 2 and 3. Polarity and data levels are field adjustable by the factory or a qualified service technician.

The LED300 features our DownShifter technology that shifts incoming DMX512 data and outputs the desired channels as channels 1, 2 and 3. This allows all fixtures to be set to address "001" with the power supply routing the proper signals to the proper outputs. To enable DownShifter mode the address switch is set to a valid DMX512 address (1 through 512). The system then operates similar to a dimmer pack with the first fixture being controlled by the selected channel (and the two successive channels), the second fixture being controlled by the selected channel plus three, the third fixture being controlled by the selected channel plus six, and so forth.

DownShifter mode is disabled (so DMX512 data passes through to every output unmodified) by setting the address switch to 000.

The LED300 can provide 5 volt differential or single ended 24 volt data. The majority of DMX512 controlled accessories that operate on 24 volt power use 5 volt differential data. Original Color Kinetics ColorBlast and iColor Cove products also used 5 volt differential data. Newer Color Kinetics ColorBlast 6 and ColorBlast 12 require 24 volt single ended data (3-wire protocol). Control data is placed on pins 2 and 3. Differential data uses pin 2 for data- and pin 3 for data+. Single ended data places the same signal on both pin 2 and pin 3 so either pin can be used for control.

The LED300 is convection cooled (no fan) for silent operation. The supply is provided with a North American Parallel Blade with Ground (PBG) mains connection.

Operating modes:

Below is a list of start address and their corresponding outcome.

• 000 = Standard power supply operation. Connected devices must be addressed as needed.
• 1 - 512 = Enables DownShifter power supply operation. Connected devices are to be addressed to start address 1.

Standalone modes:

Below is a list of start address and their corresponding outcome.

• 6nn = Fixed colors where nn selects approximate Roscolux gel color.
• 7nn = Fading effects. The tens place selects an effect and the ones place adjusts the fade time.
• 8nn = Strobe effects. The tens place selects an effect and ones place adjusts flash rate.
• 900 = Random selection of fading and strobing effects.
