About Pearson Electronics Inc

Pearson Electronics is the original and leading manufacturer for precision current-monitoring transformers used for accurate AC current measurements. The company was founded in 1955 by Dr. Paul Pearson, inventor and patent holder, of the precision wide-band current transformer.  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 Electronics has long been considered the market leader in the design
and manufacturing of Wide-Band Current Transformers used for accurate AC
current measurements. Pearson Current Transformers can 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.

 

Pearson Electronics 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.
