OPTIONS ANDACCESSORIES
EXTERNAL SHUNTS/SENSORS
If currents continuously reach above 20 amps, an external
sensor must be used. Magtrol offers three different types of
external shunts for use with Magtrol Model 7500 High-Speed
Power Analyzer.
The HA Series shunt, designed for power cable hook-up utilizing
3/8-16 screws, has an insulating base and can be mounted on
conductive surfaces. The LAB Series shunt also comes with
an insulating base, along with thumb screws for the power
leads and knurled nuts on the sensing terminals. The FL Series
is a relatively small bus, bar-mounted shunt with large end
blocks. The comparatively large end blocks and short spacing
aid in cooling and allow the shunt to operate in more extreme
environments. All shunts are calibrated on equipment with
current certifications traceable to N.I.S.T.
