Vitrek – 2503AH High Performance Power Analyzer

מאפיינים מרכזיים

Vitrek’s High-Performance Power Analyzer provides high bandwidth to 500kHz and typical 0.05% accuracy. The measurement channels can be configured independently (asynchronous or synchronous), allowing the instrument to be set up for your specific needs.

  • 18-bit, 500 kHz sampling speed provides 0.05% basic accuracy
  • Ultrafast FFT’s per channel produce measurements in 10ms
  • 3000 V Peak, 50 Amp Peak measurable with internal shunt and optional internal Hall effect CTs*
  • Pre-configured for ballast, motor, power supply, and appliance tests
  • Real-time, ultra-fast, harmonic analysis
  • Application-Specific Configurations
  • External CT and PT capability ratio: 0.000001- 1000000 to 1, for A/V, A/A or V/V
  • Frequency Measurement: 500 μHz to 170kHz, 0.01% of reading
  • Measurement Period: User-defined from 1 mSec to 27.8 hours
  • Watt, VA & VAR accuracy highest of V* Amp error or Amp* V error yields max. error for either Watts, VA, or VAR
  • Accumulation accuracy WHr, VAHr, AHr up to 9999.9 GWHr/GVAHr
  • Timing Accuracy: 0.01% + 10 mSec. start/stop error


Inputs are isolated from each other and ground for voltages up to 3000 Vpk
