|FJA4313OTU 15A NPN transistor|
One 230V, 15A, 130W 30MHz NPN transistor in a TO-247 package.
As used in the SC200 audio amplifier and 45V, 8A High-power Linear Bench Supply (four required).
|45V/8A Linear Bench Supply PCB |
The main board for the 45V 8A Linear Power Supply.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay.
150 x 120mm.
Note: some constructors have found it difficult to fit diodes D5 & D6. We believe this is due to a variation in lead thickness and body size between compatible parts. The next revision of the PCB will have larger holes spaced further apart to solve this. In the meantime, try to avoid diodes with particularly large bodies for these positions.
|High Power Linear Bench Supply PCB pattern (PDF download) |
A PDF with the PCB design for the High-power Linear Bench Supply (double-sided).
Both layers are in a single PDF.
|High Power Linear Bench Supply panel artwork and drilling/cutting diagrams (PDF download)|
A PDF of the front panel artwork for the 45V, 8A High-power Linear Bench Supply.
A separate PDF is included with all the drilling & cutting diagrams at actual size.
Note that both diagrams are 303mm wide, so neither can be printed on an A4 page at full size.
These diagrams have both been updated o 10/12/2019 to fix some things which weren't in the right place or didn't line up correctly, especially on the panel artwork.
|3mm acrylic heatsink spacer for High-power Linear Bench Supply|
A 3mm thick plastic spacer, designed to go under the Bench Supply heatsink and insulate it from the case, while still providing secure mounting and also allowing good airflow through the bottom of the fins.
