Status: Current Production
Overview
The Vitrek PA900 Series modular power analyzers provide precision power measurement for energy efficiency testing, compliance testing, and power supply characterization. The PA900 base mainframe accepts up to four measurement channels. The AD-suffix modules (PA901AD–PA904AD) provide standard power analysis. The VT-suffix modules (PA911VT–PA914VT) add voltage-only and transducer measurement capability. The UT-suffix modules (PA921UT–PA924UT) provide ultra-high accuracy for calibration laboratory use. Channel counts scale from 1 to 4 channels per mainframe, enabling single-phase to three-phase power analysis with neutral monitoring. The PA900 platform supports simultaneous measurement of voltage, current, power, power factor, harmonics, and energy with accuracy suitable for ENERGY STAR, DOE, and IEC 62301 standby power compliance testing.

Common Vitrek PA900 Series Failures We Repair
- Input channel module failures from overvoltage or overcurrent events
- Current shunt degradation affecting measurement accuracy
- Voltage divider circuit calibration drift
- Mainframe power supply failures
- Display or touchscreen failures
- Communication interface failures (USB, GPIB, LAN)
- ADC module calibration drift
- Module connector intermittent contact issues
Our technicians perform component-level diagnostics on every Vitrek PA900 Series unit. We identify and repair the specific failed components rather than replacing entire assemblies when possible, reducing your repair cost and turnaround time.
Calibration
Every Vitrek PA900 Series repair includes NIST-traceable calibration. We verify all critical measurement parameters against our reference standards and provide a detailed calibration certificate documenting measured performance against the manufacturer’s published specifications.
