Chroma A615104 Power Stage Repair and Calibration
The Chroma A615104 is a power-stage / amplifier accessory module used with Chroma AC-source and grid-simulation systems — it provides the high-power output stage that delivers programmable AC under the control of a Chroma mainframe. As a power-output module, its faults concentrate in the output amplifier stage, the regulation/control interface to the host, and cooling — not the hipot/safety faults its category label implies.
June Company repairs and calibrates the Chroma A615104 power stage for AC-source and grid-simulation users.
Common Chroma A615104 problems we fix
- Output-stage failure — no or low power output, the amplifier stage repaired so it delivers full rated output.
- Regulation / control-interface faults — the link to the controlling mainframe not working, restored.
- Output distorted or unstable — regulation degradation, recalibrated.
- Cooling or protection faults — thermal or protection shutdowns, corrected.
- Connection / power faults.
FAQs
My A615104 power stage has no output — fixable? Yes. Output-stage and control-interface faults are repairable, then verified with the host system so it delivers full rated AC, with a NIST-traceable certificate.
Do you test it with the system? Yes — the power stage is verified as part of the working AC source.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
