AC/DC power supply calibration plays a critical role in industries where electrical precision matters. From electronics manufacturing to aerospace and medical device testing, a calibrated power supply ensures stable, safe, and compliant operation. At Techmaster Electronics, we offer ISO 17025-accredited services to help you meet quality standards with confidence. Here’s what you need to know.
What Is an AC/DC Power Supply and Where Is It Used?
AC/DC power supply produce controlled alternating (AC) or direct (DC) current at set voltage and current levels. They are widely used in:
-
Electronics Manufacturing: Circuit and component testing
-
Aerospace & Defense: Avionics simulation and verification
-
Automotive: ADAS validation and sensor testing
-
Medical Devices: Safety-critical diagnostics and QA
-
Laboratories: R&D, calibration, and precision testing
Because output can drift over time, regular calibration ensures that power supply remain accurate and traceable.
Why Regular Calibration Is Essential
Power supply degrade over time due to component aging, electrical stress, or temperature fluctuations. Without calibration, you risk:
-
Inaccurate Test Results: Leading to defective products or non-compliance with standards like FDA or AS9100.
-
Costly Recalls: Critical in regulated industries like healthcare and aerospace.
-
Audit Failures: Jeopardizing ISO 9001, ISO 13485, or IATF 16949 certifications.
-
Downtime: Undetected faults can halt production.
Techmaster’s calibration service provides NIST-traceable results, early issue detection, and peace of mind for audit scenarios.
What Does the AC/DC Power Supply Calibration Process Involve?
Our calibration process uses high-precision reference standards, such as Fluke 5700A multifunction calibrators, to verify and adjust your power source’s output. Key steps include:
-
Functional Testing: Checking voltage (DC up to 1.1 kV, AC up to 1 MHz), current (up to 20 A), and frequency accuracy.
-
Verification: Comparing outputs to NIST-traceable standards, using a Test Uncertainty Ratio (TUR) of at least 4:1 for reliability.
-
Adjustment: Correcting measurement errors or drift to meet manufacturer specifications.
-
Documentation: Providing certificates linked to national standards, including test data and measurement uncertainty (ISO 17025 level)
-
Labeling: Applying calibration labels and security seals that show signs of tampering if disturbed.
Our ISO 17025-accredited labs ensure low calibration uncertainty (CMC level), such as 3.2 µV/V for DC voltage within the 2.2–11 V range.

In-House vs. Professional Calibration: A Clear Comparison
| Factor | In-House Calibration | Professional Calibration |
|---|---|---|
| Equipment Costs | High investment | Included in service |
| Expertise | Requires in-house staff | Certified metrology professionals |
| Standards | Often limited | ISO 17025, NIST traceability included |
| Audit Readiness | Risk of missing compliance | Audit-proof documentation |
| Speed | Variable | Fast turnaround, on-site available |
Outsourcing calibration isn’t just easier—it’s smarter. For SMEs and regulated industries, Techmaster offers scalable, cost-efficient, and fully accredited services, including on-site calibration to minimize downtime.
How Often Should You Calibrate Your AC/DC Power Supply?
The ideal calibration interval depends on your usage and environment:
-
Annually: Suitable for most production and lab settings
-
Every 6 months or quarterly: For high-use or critical operations
-
After repairs or environmental stress: If exposed to shocks, relocation, humidity, or surges
