If the power supply output does not appear to meet specifications, please check the following points to isolate the cause:
- Inspect the Load Condition: Disconnect the load to measure the output in an open-circuit state (or with a known dummy load). This helps determine if the issue is caused by load fluctuations or the power supply itself.
- Review the Measurement Setup: Ensure measurement cables are short and routed away from noise sources. Long leads can introduce voltage drops or pick up environmental noise, leading to measurement errors.
- Verify the Operating Environment: Confirm that the ambient temperature is stable and within the specified operating range. Extreme temperatures can cause performance drift.
- Ensure Proper Warm-Up: Allow the power supply to warm up for the required time (typically 30 minutes). Specifications are generally guaranteed only after the unit reaches thermal equilibrium.
- Confirm the Guaranteed Specification Range: Ensure the operating point is within the guaranteed range. Some specifications, such as linearity or ripple, may not be guaranteed at very low settings (e.g., below 10% of the rated output).
