The Voltech PM100 is a single-phase power analyzer delivering precise measurement of electrical parameters across DC to 250 kHz. Built for design, development, and production testing of electrical and electronic equipment, it combines ±0.1% basic accuracy with a graphics display capable of rendering waveforms and harmonic bar-charts. The instrument measures voltage, current, power, reactive power, power factor, harmonics to the 50th order with phase information, and integrated energy values. Its direct input ranges extend from 2 Vrms to 1000 Vpk and 20 mArms to 20 Arms via internal shunts, with external transducer support for measurements exceeding these limits.
