What Is a Power Supply?
A power supply is an electrical device that delivers energy to a load by converting input power into the voltage and current required by electronic equipment. Power supplies may provide direct current, alternating current, or both, depending on the application.
Power supplies are commonly used in engineering, production test, quality control, maintenance, validation, research, and regulated manufacturing environments. Because stable voltage and current output can affect test results, equipment performance, product validation, and compliance decisions, regular calibration helps confirm that power supplies remain accurate, traceable, and reliable.
Common Types of Power Supplies
SIMCO supports calibration for common power supply types, including:
- DC power supplies used for direct current testing and equipment operation
- AC power supplies used for alternating current simulation and validation
- Programmable power supplies used in automated test systems and repeatable test workflows
- Bench power supplies used in engineering, troubleshooting, and production test environments
- Linear power supplies used for low-noise and precision applications
- Switching power supplies used in production, validation, and functional testing
- High-voltage power supplies used for specialized test and measurement applications
- Variable frequency power sources used for power simulation and product validation

- Inspection of instrument condition, outputs, displays, controls, and accessories
- DC voltage and current output verification
- AC voltage, current, and frequency verification, when applicable
- Multi-point testing across specified output ranges
- Load regulation and line regulation checks
- Ripple and noise measurement, when required
- Display-versus-output verification
- Calibration using appropriate reference standards and procedures
- Adjustment, when supported by the instrument and service scope
- As-found and as-left results, when required
- Calibration certificates with test points, tolerances, uncertainties, and traceable documentation
Why Power Supply Calibration Matters
Power supplies can drift over time due to component aging, temperature changes, humidity, electrical stress, line voltage variation, environmental conditions, or normal wear. These changes can affect voltage accuracy, current accuracy, ripple, noise, and overall output stability.
Calibration helps support:
- Output accuracy: Confirms voltage, current, frequency, and other output parameters are within required tolerances.
- Reliable testing: Helps ensure power supplies used in validation, troubleshooting, and production test deliver consistent output.
- Compliance and audit readiness: Provides traceable documentation for quality systems, customer requirements, and regulated environments.
- Risk reduction: Helps reduce false test results, equipment performance issues, rework, failed validation, and quality escapes.
