Description

California Instruments RS90-3PI Power Test System Repair and Calibration

The California Instruments RS90-3PI is a high-power three-phase programmable AC power source/test system — it generates programmable three-phase AC (with measurement) for testing avionics, industrial, and three-phase products against demanding line conditions. As a high-power multi-phase AC system, its faults concentrate in the power amplifier stages, waveform/regulation, and the control electronics.

June Company repairs and calibrates the California Instruments RS90-3PI for avionics, industrial, and three-phase product test teams.

Common RS90-3PI problems we fix

A phase won’t reach output — power-amplifier-stage failure on one phase, repaired so all three phases source rated output.
Waveform distorted or frequency off — waveform-generation/regulation faults, recalibrated for clean AC at the set frequency.
Power measurement inaccurate — the metering drifting, recalibrated against standards.
Goes into fault/shutdown — protection or power faults, repaired.
Control or interface faults.

FAQs

One phase is dead on my RS90 — fixable? Yes. Per-phase amplifier faults are repairable, then all three phases are verified against rated output, with a NIST-traceable certificate.

Is the measurement verified? Yes — output and metering are checked 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.
