Intelligent Dual Hybrid Power Supply regulator PCB [18107211]
The main regulator PCB for the Hybrid Power Supply.
You will need two if you want to build the dual-channel version as described in the magazine. It is also possible to build a single-channel version. This PCB is also available as part of a complete set for the project.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay.
116 x 133mm.

Intelligent Dual Hybrid Power Supply front panel control PCB [18107212]
The small front panel PCB for the Hybrid Power Supply.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay. This PCB is also available as part of a complete set for the project.
74.5 x 23mm.

 |
DSP Crossover CPU PCB [01106193]
The central processor PCB for the DSP Active Crossover. Also used for the Low-distortion DDS Signal Generator, DIY Reflow Oven Controller and Intelligent Dual Hybrid Power Supply.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay.
60 x 62mm
|
 |
DSP Crossover LCD Adaptor PCB [01106196]
The LCD Adaptor PCB for the DSP Active Crossover. Also used for the Low-distortion DDS Signal Generator, DIY Reflow Oven Controller and Intelligent Dual Hybrid Power Supply.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay.
51 x 13mm.

Intelligent Dual Hybrid Power Supply PCB patterns [18107211/2]
Two PDFs with the PCB designs for the Dual Hybrid Power Supply (both double-sided).
Both layers of each design are in their own PDFs.

 |
DSP Active Crossover/DDS/Reflow Oven PCB patterns (PDF download) [01106191-6]
PDF with the PCB designs for the six boards used in the DSP Active Crossover project (all double-sided).
These same boards (except for the one coded 01106191) were also used in the February 2020 Low-distortion DDS Signal Generator project.
Similarly, the subset of boards coded 01106193, 01106195 and 01106196 were used in the DIY Reflow Oven Controller project from the April 2020 issue.
The boards coded 01106193 & 01106196 were used again in the Intelligent Hybrid Power Supply (February & March 2022).
Both layers of all boards are in a single PDF, one PCB per page.

LCD panel bezel for the Dual Intelligent Hybrid Power Supply
A bezel for the Intelligent Dual Hybrid PSU LCD, laser cut from 3mm-thick clear acrylic.
As per the article, you will need to mask the centre and paint the outer areas to get a good appearance; the edges of the area to mask are laser etched and the mounting holes are pre-cut.
NOTE: The overall dimensions of the bezel have been made slightly larger than the dimensions in the article. New dimensions are 97x74mm.

Hard-to-get parts for the Intelligent Dual Hybrid Power Supply regulator board
A partial set of parts to build one regulator board for this project. See the parts list link below for details on what is included.
The PCB is not included but we can supply it separately or as part of a PCB set. The rest of the parts needed to build the regulator module are readily available.
The LM2575 regulator is not included in this kit; as only one is needed per device, it is included in the CPU board parts set (or get it from Altronics).
Two of these parts sets are needed to build the dual version of the supply.
Note: Image shows assembled regulator board.

Hard-to-get parts for the Intelligent Dual Hybrid Power Supply CPU board
A partial set of parts to build the CPU/control board for this project. See the parts list link below for details on what is included.
The PCB is not included but it is available from us separately or as part of a set. The LM2575 regulator mounts on one of the regulator boards, but as only one is needed per device, it is included in this set of parts.
The rest of the parts needed to build the CPU module are readily available.
Note: Image shows assembled CPU board.
