Description
Haefely AXOS5 Compact Immunity Test System Repair
The Haefely AXOS5 is a compact EMC immunity test system — it combines surge, EFT/burst, and (configuration-dependent) ring-wave and dips/interrupts generators with a coupling/decoupling network in one unit, for testing products to IEC 61000-4 immunity standards. As a multi-generator EMC system, its faults span the impulse/power stages, the waveform generation, the CDN, and the protection/control electronics.
June Company repairs and calibrates the Haefely AXOS5 for EMC test labs and product-compliance teams.
Common Haefely AXOS5 problems we fix
- Power-stage rebuilds — a surge or EFT generator not producing its waveform, the impulse/power stage repaired for correct output.
- Waveform-generator repair — distorted or out-of-tolerance waveforms, corrected to the IEC standard’s parameters.
- Protection-circuit reset / faults — the unit locking out or tripping, repaired.
- CDN / coupling faults — the coupling-decoupling network not coupling correctly to the EUT, restored.
- Control or interface faults.
FAQs
My AXOS5 surge or EFT waveform is out of spec — fixable? Yes. Waveform and power-stage faults are repairable, then verified against the IEC 61000-4 tolerances, with NIST-traceable calibration.
Are all generators verified? Yes — each installed test function is checked against the standard.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
