RXT_G I Custom ACP MCU PCB

Back in the day, c1992, ACP built its first LongRanger generator trailer. They chose to use a Generac RV - NP72G platform, and modified that unit from an AC to a DC output, among other details. Here is a picture of the custom ACP MCU PCB used in that early prototype unit.

The Beata Collections unit was purchased with a fault that we are working on resolving. Here is a closeup of an overheated and damaged Bridge Rectifier on the custom PCB.

Another angle on the primary damage.

As we found and began assessing the damaged PCB, we decided to simply replace the Bridge Rectifier, a C-RDF005, and use a temporary mounting DIP IC socket adapter to make it a bit easier to test and re-test components. Pictured here with a replacement Bridge Rectifier in place.

The following pictures are up-close high resolution angles on the prototype board.

Note the newly installed Bridge Rectifier, now damaged from our first test run.

Note the 7808C Voltage Regulator, also replaced in round 1 and mounted on a DIP IC socket adapter.

This document shows some of the work necessary to begin diagnosing the PCBs design, in this case the carbon resistor values are noted and the metal film resistor values are being determined.
