Modification of ARTESYN 7001138 for a 13.5 V DC 69 A Power Supply

posted in: Information | 0

A surplus or unused ARTESYN 7001138-Y000 REV H was modified to be used as a 13.5 V DC 69 Ampere power supply. Here are steps in pictures which show the modification process.

Connect a 5 kOhm variable resistor between pin 17 and ground to adjust the output voltage to maximum of 13.6 Volt. If the output voltage increase more than 13.6 Volt, the PS would be shutdown as it is protected from over voltage above 13.6 V DC.
