Tiger DMX DC Controllers
TigerDMX48HC DC Controller.
The TigerDMX48HC DC controller is designed for use with DC Low voltage Christmas lights.
The TigerDMX48HC DC controller can work from 12v to 55v DC and is powered by the same voltage
as lights and can switch up to 2.5A per channel with a max load for each 24 channels of 30 Amps.
Features
- 48 channels
- 12v DC to 55v DC
- DMX512A input - RJ45 Connectors
- 2.5A Max per channel limited to 30A per 24ch
- Output via screw terminal blocks
- 1Mb Onboard memory for hardware dimming curves (dimming curves not implemented in firmware yet)
- Onboard 5v Switched Mode Power
- Dual Power input - different voltage levels supported
- Header for Wireless DMX Receiver outputing serial data
TigerDMX48HC Version 4x
Progress updates can be found over on the support forum TigerDMX48 Board The feature set remains the same with a move to more surface mount components.Cost
Preliminary costing will be around US$115 as a kit with all components. Kits will have all surface mount components reflow soldered onto the board. This will leave only the thru hole components to be soldered and firmware loaded to the PIC. Completed and tested units will be available in limited quantities for US$145 Packing and Shipping Charges not includedPlease email me if you would like to know more
TigerDMX48HC Version 1
This board was the one I used for Christmas 2009 and is shown in the picture below. Though this board quite succesfully run 350 channels of my Christmas lightshow in 2009 the board had a couple of issues with trace and component layout that stopped it being released to the community. The issues were easy to work around and have been fully corrected for the version 4 boards. The picture below shows two boards, the one on the left is being powered by dual 27v feeds, whilst the one on the right has a single 48v feed. The boards allow two different voltages to be used if needed and one of my controllers had one side 27v and the other 48v.
What! - you actually scrolled all the way down here. Well then i can tell you what happened to v2 and v3 designs. Version 2 was an attempt to narrow the board down, it was more painful than i thought and dropped. Version 3 was a component shuffle to space the mosfets correctly so a heatsink could be used. This went as far as component placement and was stopped in favour of using SMD mosfets. Version numbers have been incremented just to keep track in the PCB software more than any other reason.
