We Verify Your Drives and Electronic Components for Authenticity
Authenticity Check for Drives & Electronic Components: Confidence Before You Invest
Prevent failures caused by hidden counterfeits.
With our professional authenticity verification, you ensure
that your drives and system components truly meet original manufacturer quality before being installed in critical processes.
Why Authenticity Check Is Essential Today
The market for industrial drives, motors, and control components is globally interconnected. Components are traded through various channels, new, used, refurbished, or from warehouse stock.
As shown in our article Solutions Against Counterfeit Drive Components, products with unclear origin or altered substance repeatedly enter industrial supply chains.
For buyers, it is often not clearly recognizable:
- Whether it is an original product from the manufacturer
- Whether the device has been opened or technically modified
- Whether serial numbers and nameplates are authentic
- Whether all components correspond to the original condition
Especially in production-critical systems, unverified components can lead to downtime or consequential damage.
Professional authenticity verification provides clarity before the component is installed or resold.
What Exactly Is Checked During Authenticity Check?
Inspection of Nameplate and Serial Number
We compare serial numbers, production markings, and device designations with our technical reference data and manufacturer standards, checking them for plausibility and irregularities.
Visual and Mechanical Inspection
Our technicians professionally open the device and examine housing, screws, seals, connectors, and internal assemblies for signs of manipulation, replacement traces, or deviations from the original condition.
Electrical Measurements and Functional Testing
We test power and control units on our test benches under realistic conditions and verify whether the technical parameters comply with manufacturer specifications.
Software and Parameter Analysis
By reading firmware versions, parameters, and internal device data, we identify modifications, non-original configurations, or inconsistent software versions.
Comprehensive Technical Evaluation
Based on all inspections, we prepare a well-founded overall assessment, transparently document the device condition, and provide you with a clear recommendation for further use, repair, or replacement.
Who Our Authenticity Check Is the Right Choice For
Maintenance Personnel and Technicians
Safety before installation: verification of drives and motors to prevent unplanned downtime.
Purchasing and Procurement
Protection against incorrect purchases through technical inspection of serial numbers, condition, and authenticity.
Quality Management
Documented test results for internal quality assurance and audit purposes.
Machine and Plant Manufacturers
Reliable verification of components to safeguard customer projects and contractual commitments.
Distributors and Resellers
Transparent evaluation of device condition to enable trustworthy resale.
