Pearson Electronics, Inc.

Pearson Electronics is the original and leading manufacturer for precision current-monitoring transformers used for accurate AC current measurements. The Pearson design plus careful workmanship and quality control produce current monitors with excellent frequency response and amplitude accuracy. Originally developed for measuring pulse-currents, Pearson Current Monitors™ are now also widely used to measure more complicated transients and periodic signals from a few Hertz to well into the megaHertz region. Pearson Wide-Band Precision Current Transformers can accurately measure transients, harmonics, pulse, sine-wave, RF and other complex current wave shapes. A frequency range from 0.7 Hz to 350 MHz is covered, with our most popular model covering 1 Hz to 20 MHz ± 3 dB. 1% accuracy, or better, is obtainable over the mid-band. The current range is from micro-amps to kilo-amps and we manufacture both toroid and clamp-on Current Transformers. We stock a large variety of models for immediate delivery and design and manufacture for both OEM and custom requirements. The company also specializes in the design of High Voltage Pulse Transformers that are used with high power microwave tubes and Capacitive Voltage Dividers. These transformers employ open construction and are intended to be used in high voltage insulating oil. Pulse output voltages range from 100kV to 500kV with pulse lengths from 0.25 to 50 microseconds.
