Description

Chroma 6490 AC Source Repair and Calibration

The Chroma 6490 is a programmable AC power source — it generates clean, programmable AC voltage, frequency, and waveform (including harmonics and 400 Hz) with built-in power measurement, for testing products against varying line conditions. As an AC-generation instrument, its faults concentrate in the output amplifier stage, waveform/regulation circuitry, and measurement — not the hipot/ground-fault faults its category label implies.

June Company repairs and calibrates the Chroma 6490 for product-test and production teams.

Common Chroma 6490 problems we fix

No output or won’t reach setpoint — AC output-amplifier failure, repaired so it sources full programmed voltage and current.
Waveform distorted or frequency off — waveform-generation or regulation degradation, recalibrated for clean AC at the set frequency.
Power measurement off — the built-in metering drifting, recalibrated.
Won’t program or communicate — remote-interface faults, restored.
Fan or protection-shutdown faults.

FAQs

My 6490 output is distorted — fixable? Yes. Waveform and regulation faults are repairable, then verified so it delivers a clean AC output at the programmed voltage and frequency, with a NIST-traceable certificate.

Is the power measurement verified? Yes — the metering is recalibrated against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.

Shipping & Returns

Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.

Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
