Precision power analyzers measure mechanical and electrical power, offering the highest power analysis accuracy so users can capture the most elusive waveforms. Test engineers diagnosing the performance of transformers, lighting electronics, switching electronics, inverters and AC or DC power supplies rely on precision power analyzers for their measurements. ATEC offers precision power analyzers from Yokogawa, Voltech (acquired by Tektronix) and Zimmer with single-phase, three-phase and six-phase testing capabilities.
