Description

Sorensen SGI800-37.5 Power Supply Repair and Calibration

The Sorensen SGI800-37.5 is a high-power programmable DC power supply — 800 V / 37.5 A, ~30 kW, from the SGI series built for high-power test and industrial applications. At this power level the output stage, the high-current/high-voltage sections, and cooling carry serious stress, which is where faults appear.

June Company repairs and calibrates the Sorensen SGI800-37.5 for high-power test and industrial users.

Common Sorensen SGI800-37.5 problems we fix

Won’t reach voltage or current — output-stage failure on a high-power unit, rebuilt so it sources full 800 V / 37.5 A.
Line regulation off — regulation-loop drift, recalibrated so it holds setpoint across line variation.
Remote-sensing faults — the sense circuit that corrects for lead drop, repaired.
Cooling or thermal-shutdown faults — high-power cooling service.
Programming/communication faults — restored.

FAQs

My SGI won’t reach full output — repairable? Yes. High-power output-stage faults are serviceable; we restore full rated voltage and current and recalibrate, with a NIST-traceable certificate.

Is regulation and remote sensing verified? Yes — line regulation and remote sensing are checked against spec.

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.
