California Instruments MX30-3PI Power Supply Repair and Calibration
The California Instruments MX30-3Pi is a high-power programmable AC (and DC) power source — a 30 kVA-class three-phase source that generates clean, programmable AC line conditions with measurement, for high-power product, avionics, and aerospace testing. As a high-power AC-generation system, its faults concentrate in the output amplifier/power stage, waveform/regulation, and the measurement system.
June Company repairs and calibrates the California Instruments MX30-3Pi for high-power product-test and aerospace teams.
Common California Instruments MX30-3Pi problems we fix
- Ripple and noise increase — output filtering/regulation degradation raising noise, corrected to spec.
- Load-regulation faults — output won’t hold under load, the regulation loop repaired and recalibrated.
- No output / a phase down — output power-stage failure on a phase, repaired so all phases source full output.
- Waveform distorted or frequency off — waveform-generation degradation, recalibrated for clean AC.
- Measurement, cooling, or interface faults.
FAQs
My MX30-3Pi output is noisy or a phase is down — fixable? Yes. Output power-stage and regulation faults are repairable, then verified so all phases deliver clean AC at the programmed setpoint, 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.
