California Instruments 6000LS Power Source Repair and Calibration
The California Instruments 6000LS is a high-power programmable AC power source — a 6000 VA-class AC source (the “LS” denotes the low-output-impedance/high-current configuration) for testing avionics, industrial, and demanding AC-powered products against varying line conditions. As a high-power AC source, its faults concentrate in the output amplifier stage, waveform/regulation, and measurement.
June Company repairs and calibrates the California Instruments 6000LS for avionics, industrial, and product-test teams.
Common California Instruments 6000LS problems we fix
- Voltage-regulation faults — output won’t hold the programmed setpoint under load, the regulation loop repaired and recalibrated.
- No output or won’t reach setpoint — output-amplifier failure, repaired so it sources full programmed voltage and current.
- Waveform distorted or frequency off — waveform-generation degradation, recalibrated for clean AC at the set frequency.
- Power measurement off — the metering drifting, recalibrated.
- Fan, protection, or control-interface faults.
FAQs
My 6000LS won’t hold output under load — fixable? Yes. Output-amplifier and regulation faults are repairable, then verified so it delivers 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.
