Proven Performance In Regulated Industries
Millspaw Electronics has grown into a trusted provider of specialized electronic services for highly regulated sectors—including Commercial, Nuclear, Department of Energy (DOE), and Department of Defense (DOD). Since 2023, we’ve completed numerous projects that demand precision, quality, and compliance. Our operations align with critical industry standards, including NIST 800-171, CMMC Level 2 Audited, NQA-1, IPC610 compliant and 10CFR50 Appendix B (NUPIC checklist audited), reflecting our commitment to technical excellence and rigorous quality assurance.
Past Performances
Products that demonstrate our precision, compliance, and mission-critical reliability.
Reconfigure and Refurbished Power Supply
Challenge:
When the plant converted from 50 Hz to 60 Hz, three legacy GE 9T66Y988 power‑supply modules lost regulation; one unit also suffered a broken winding.
Solution:
We retuned each supply for 60 Hz, refreshed key capacitors, repaired the damaged coil, and completed a 100‑hour nuclear‑grade burn‑in—all in close coordination with the plant’s engineering team.
Outcome:
All three modules now operate flawlessly at 60 Hz, restoring uptime and pushing service life to 2032—saving the client a costly OEM replacement.
Cyberex DC Repair
Challenge:
Shelf‑life‑limited electrolytic capacitors on two legacy converters were nearing expiration, risking future failure—even though the units still passed functional tests.
Solution:
We replaced all six critical capacitors with new high‑reliability Vishay parts, secured them with RTV, cleaned the boards to IPC‑A‑610 Class 2, and completed a 100‑hour burn‑in.
Outcome:
Shelf life reset to 2033, converters fully compliant and ready for another decade of service—eliminating the need for expensive new units.
Transfer Switch Refurbish
Challenge:
A severe electrical fire inside the ASCO E7ATS3400N5 automatic-transfer switch destroyed the main control PCB, charred the LCD PCB, burned the solenoid and several wiring harnesses, cracked the switch back-plane, and carbon-scored one of the main contact pads. The root cause was traced to a limit-switch on the “Normal” position that failed to trigger; the control logic kept driving the solenoid, overheated the assembly, and ignited the board.
How we brought it back to life:
- Replaced the entire back-plane, main switch assembly, LCD panel/PCB, control PCB, solenoid, and four wiring harnesses with parts harvested from an identical donor unit.
- Refreshed all shelf-life-limited parts: eight aluminum electrolytic capacitors and the coin-cell backup battery were swapped for new, date-code-current equivalents.
- Installed a new three-position transfer-control switch and two new indicator LEDs on the operator panel.
- Removed unneeded option wires, re-pinned harnesses to match the original configuration, cleaned and re-lubricated all mechanical linkages, and secured hardware with thread-locker.
- Performed a 100-hour loaded burn-in, workmanship inspection per IPC-A-610 Class 2, and full functional testing—unit passed with no deviations.
Outcome:
The transfer switch now functions exactly as it did when new, with form, fit, and function fully restored and shelf life extended to April 2033—avoiding an expensive replacement unit.
Relay Repair
Challenge:
A legacy ABB KD-11 distance relay arrived with a shattered front cover and a broken rear finger-guard—mechanical damage that threatened long-term reliability despite passing functional tests.
Solution:
We sourced like-for-like surplus parts, refurbished and installed a replacement cover and terminal-block frame, then ran a 24-hour burn-in and final functional/ workmanship inspections.
Outcome:
The relay now meets its original form, fit, and function, ready for service without the cost or lead-time of an OEM replacement.
