Is your industrial power supply exhibiting intermittent output voltage, causing equipment to shut down, restart, or operate erratically? ROC Industrial specializes in diagnosing and repairing power supplies with intermittent output problems. These issues can be particularly challenging to troubleshoot, but our experienced technicians have the skills and tools to identify the root cause and provide a reliable repair.
Understanding Intermittent Output Problems
Intermittent output voltage means that the power supply's output fluctuates, drops out completely for short periods, or otherwise behaves unpredictably. This is often more difficult to diagnose than a complete failure, as the problem may not be present all the time.
Common Causes of Intermittent Output
Loose Connections: Internal or external loose connections are a very common cause of intermittent problems. Vibration, thermal cycling, or poor initial connections can lead to this.
Failing Components: Components that are starting to fail, but haven't failed completely, can cause intermittent issues. This is common with capacitors, but can occur with other components as well.
Thermal Issues: Overheating components can cause intermittent operation. A component might work fine when cold, but fail as it heats up.
Cracked Solder Joints: Cracked or "cold" solder joints can create intermittent connections.
Damaged Traces: Fine cracks in the circuit board traces can cause intermittent breaks in the circuit.

Our Intermittent Output Repair Process
Free Evaluation & Quote: Describe the problem in detail, including how often the intermittency occurs, any triggering events, and the power supply model. The more information you can provide, the better. We provide a free quote.
Shipping: Ship the power supply to our facility.
Diagnosis: This is the most critical step for intermittent problems. Our technicians use a combination of techniques, which may include:Visual Inspection: Carefully examining the circuit board for any signs of damage, loose components, or cold solder joints.
Thermal Testing: Using a thermal camera to identify components that are overheating.
Oscilloscope Monitoring: Monitoring the output voltage over time to capture intermittent drops or fluctuations.
Component Testing: Testing individual components (capacitors, resistors, etc.) to see if they are operating within specifications.
"Tap Testing": Gently tapping on components and the circuit board to see if this triggers the intermittent fault (this can help identify loose connections or cracked solder joints).Repair/Replacement: Once the cause is identified, we perform the necessary repairs, which may involve:Resoldering connections.
Replacing failing components.
Repairing damaged traces.
Tightening loose connections.Testing & Quality Assurance: We thoroughly test the repaired power supply under load, often for an extended period, to ensure the intermittent problem is completely resolved.
Fast Turnaround: Minimize downtime.
Warranty: We offer a comprehensive warranty.
