Status: Vitrek PA900 Series power analyzer repair covers the full modular PA900, PA910, and PA920 range with all channel-card configurations. We repair and calibrate all of them.
Common Vitrek PA900 Series Problems We Fix
- A channel reads wrong or won’t measure — input channel card failure from an overvoltage or overcurrent event
- Current readings drifting — current shunt degradation
- Voltage readings off — voltage divider calibration drift
- Won’t power up or resets — mainframe power supply failure
- Display or touchscreen unresponsive
- Won’t connect to your test station — USB, GPIB, or LAN interface failure
- Accuracy off across channels — ADC module calibration drift
- A card works only when reseated — module connector contact issue

Frequently Asked Questions
How much does Vitrek PA900 Series power analyzer repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the analyzer, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast. Multi-channel recalibration across all installed cards can add time — we’ll tell you up front with the quote.
One channel reads wrong after an overvoltage event — can you fix it?
Yes. Input channel-card damage from an overvoltage or overcurrent event is the most common PA900 fault, and because the platform is modular we can repair or service the affected channel without touching the rest, then verify it against our reference standards.
My current or voltage readings have drifted — is that repairable?
Yes. Current-shunt degradation and voltage-divider drift are repairable and recalibrated, restoring the precision accuracy the PA900 is bought for.
My readings are out of spec — can you recalibrate and certify it?
Yes. Every repair includes recalibration against our reference standards across all installed channels, with a NIST-traceable certificate — the documentation your ENERGY STAR, DOE, or IEC 62301 standby-power program needs.
I use mine for EV, solar, motor, or 400 Hz avionics power testing — can you still service it?
Yes. We service the full PA900 range regardless of how it’s configured, including units set up for inverter/EV, PV efficiency, motor-drive, and aviation-frequency harmonic work, and we recalibrate the channels and functions your application depends on.
What if my exact configuration isn’t listed?
We service the full PA900, PA910, and PA920 line in any channel-card combination, 1 through 4 channels. If your configuration isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the Vitrek PA900 Series?
Power-supply and power-electronics manufacturers, energy-efficiency and ENERGY STAR compliance labs, appliance and lighting test labs, EV/inverter and solar developers, and calibration laboratories rely on the PA900 modular analyzers to measure voltage, current, power, power factor, harmonics, and energy.
