A new line of Wide-Band Clamp-on Current Monitors from Pearson Electronics feature a ½ inch or 1 inch aperture and are hinged for easy operation. The new design incorporates Pearson’s wide band frequency response in a demountable configuration for use on fixed conductors.

The model 411C, typical of the group, has a sensitivity of 0.1 V/A, a 3dB bandwidth from 15 Hz to 20 MHz, and a 50 Ampere rms current rating. Accuracy of 1%, or less, is obtainable across the mid-band.  Pulse currents up to 5,000 Amperes and rise times down to 20 nanoseconds can be viewed faithfully.  Other new hinged clamp-on designs feature a range of transfer impedance from 0.01 V/A to 1.0 V/A. Electrical specifications range from rise times as short as 2.0 nanoseconds, or droop as low as 0.003% per microsecond.  All of the new hinged clamp-ons are featured in our Clamp-on Current Monitor section along with existing custom and stock designs.

 

 

Pearson Electronics introduces a new wide band current monitor that allows you to easily measure current within a coaxial cable system.  The current monitor can be inserted within a coaxial cable run by means of two BNC connectors. The Model 6027 has a 3dB bandwidth from 300 Hz to 200 MHz and an rms current rating of 2.5 Amperes.   Accuracy of 1%, or better, is obtainable across the mid-band.  Pulse currents up to 100 Amperes peak and rise times as short as 2 nanoseconds can be viewed faithfully. Other coaxial designs include ones with HN and triax connectors as well as ones that are double shielded.

Several new ultra-thin  wide band current transformers have been released by Pearson Electronics with a thickness that is around 1/2 the size of standard / in stock current transformers designed by Pearson.  These new ultra thin broadband current transformers allow a more compact installation resulting in lower circuit inductance. Apertures range in size from 0.25 inches to 2.0 inches and the models have the same footprint as our in stock current monitors, except for thickness.  Designs include BNC and SMA connectors depending upon the model.

These designs incorporate Pearson’s wide-band frequency response and 1% accuracy, or better, across the mid-band. The model 8500 has a 2.0 inch aperture, a 0.1 V/A transfer impedance with a 3 dB bandwidth from 10Hz to 20MHz. The maximum rms current rating is 75 Amperes.  Peak currents up to 5,000 Amperes and rise times as short as 20 nanoseconds can be viewed faithfully.  Contact a Pearson Electronics for a complete listing of the ultra thin current transformers.

fast hinged clamp on current monitorsPearson Electronics is pleased to introduce two new Wide-Band Hinged Clamp-on Current Monitors with fast rise times.  The models 8585C and 8590C feature a 2.0 and 2.5 nanosecond rise times, a ½ inch and 1 inch aperture, and are hinged for easy operation. The new design incorporates Pearson’s wide band frequency response in a demountable configuration for use on fixed conductors.

Both models have a 1.0 V/A sensitivity, a 3dB bandwidth from approximately 1.0 KHz to 200 MHz, and a 5 Ampere rms current rating. Accuracy of 1%, or less, is obtainable across the mid-band.  Pulse currents up to 500 Amperes can be viewed. Other new hinged clamp-on designs feature a range of transfer impedance from 0.01 V/A to 1.0 V/A allowing for accurate measurements at lower frequencies.  A typical model has a 3 dB bandwidth of 25Hz to 15 MHz, with some models as low as 5 Hz.  All of the new hinged clamp-ons are featured in our Clamp-on Current Monitor section along with existing custom and stock designs.

 

Pearson Electronics Powerline Ripple Detector, model PRD-120 and PRD-240, greatly simplifies the measurement of injected audio-frequency ripple on an ac power bus in EMI tests such as MIL-STD-461G CS101.   

•    Accurate measurements of CS101 over the entire frequency domain
•    Separates the injected ripple from the power waveform.
•    Used with a spectrum analyzer, simplifying the test set up and measurement process.
•    Works on an AC, or DC, power bus.
•    Two models: PRD-120 for 120Vac.  PRD-240 for 240 Vac; 270 Vdc applications.

 

MIL-STD-461 ProbePearson Electronics is pleased to introduce a new Injection Probe, Current Probe and Test Fixture specifically designed for meeting MIL-STD-461 and RTCA/DO-160 requirements.  This new compact design includes a 2.0 inch Probe aperture for easier use and requires only one Test Fixture to accommodate both Probes.

Features:

  • Designed for sections CS 114/115 and 116 in MIL-STD-461
  • F-3 Test Fixture accommodates both probes simultaneously, supporting MIL-STD-461G
  • Wideband frequency response, 10 kHz to 400 MHz
  • Maximum Input Power 100W for 30 minutes, case temperature less than 50° C
  • Sleek compact Probe design with larger 2.0 inch aperture
