These Power Driver boards were developed late 2023,
as the original boards had a few design flaws with older obsolete components,
my boards have been up-dated with modern SMD components but still use through hole transistors,
a lot of research / development was done i improve on the original design,
i have used a TO-3 type switching 5 volt regulator, for ease of replacement if the need should ever arise.
Back in 2023 i had only manufactured a small batch run for full testing in the machines at the arcade i work at,
now having many requests for a power driver board, i have put these into full production ..
OEM style diodes to protect the IC's from surge currents
3 LED's to show +5v (red) , 11.9v (yellow) & 48v (blue)
Heavy duty Relay with green LED to show activated
Modern components having a higher rating
Original style lay out for troubleshooting
Through hole components for service
Test points to check all voltages
No custom chips !

Please Note :- Does NOT have High voltage section on these boards as they are designed to suit LED displays.
