Ohm-Labs’ CSA series of ac current shunts are designed as calibration standards for ac current measurement up to high frequencies. Lower current CSA shunts may be used as AC resistance standards.
CSA shunts are optimized for 1 volt output. Standard models provide overlapping ranges to cover nearly all measurement applications.
Up to 2 A, specially constructed foil elements provide low inductance and flat frequency response.
Above 2 A, unlike other commercially available ac shunts, which use chip resistors in a ‘cage’ construction, Ohm-Labs uses a true coaxial foil design, for close ac/dc conformance up to 100 A at 100 kHz.
Careful heat treatment and characterization of the foil resistance alloy gives low temperature coefficients, for minimal change with 0-100 % applied current.
Potential connection is type N male. Current up to 10 A is type N female. 20, 50 & 100 A current connection is with LC female connectors.
Coaxial Tee connnectors, for 10 A or 100 A, allow comparison calibration of AC shunts.
CSA-Shunts are available as a set (CSA-Set), including connectors and transit cases.
All shunts include ISO17025 Accredited Calibration through full dc current and ac-dc difference up to 100 kHz.
Ohm-Labs shunts are warranted for two years.
