PRODUCT OVERVIEW
2
Teledyne Test Tools Rogowski Current probes oer a broad range of products covering a wide frequency span
and current measurement ranges for maximum application coverage whilst being easy to use in dicult to
reach parts of the circuit.
The exibility of the probe sense coil means that measurements can often be made without modication to the
circuit under test, giving more accurate results, whilst remaining isolated, with very low insertion load of only a
few pH.
The inclusion of both battery power and wall plug operation means that the Teledyne Test Tools Rogowski
Current Probes are as happy working out in the eld as they are working on the bench.
The T3RC0300-UM features our smallest cross section sense coil at only 1.7mm. This ideally lends itself to
embedded power applications where it’s necessary to probe around the leg of power components such as
inductors, capacitors or small switching devices as small as a TO220 MOSFET.
The T3RC0600-HF and T3RC3000-HF are general purpose Rogowski probes covering applications up to 600
Amps and 3000 Amps respectively. With extended high frequency coverage, 5 kV peak insulation and wide
operating temperature range from -40C to +125C, makes them ideally suited to both general purpose as well as
wide temperature environments.
The T3RC3000-LF and T3RC6000-LF Rogowski probes oer an extended low frequency performance down to
less than 1 Hz. The low frequency performance means that the maximum droop on low frequency pulses is
typically 0.1% / ms or less, whilst oering our highest level of peak insulation of 10 kV and wide operating
temperature range of -20C to +100C.
Main Features
5 dierent probes covering a wide range of
applications.
Maximum current measurement coverage up
to 6000 Amps.
Maximum voltage insulation up to 10 kV
peak.
Connect to a wall plug or use with batteries.
Low loading of the circuit under test.
Wide coil operating temperature from -40 C
to +125 C on UM and HF probes. -20 C to
+100 C for LF probes.
Use without modication to the DUT.
Oscilloscope Compatibility
The Teledyne Test Tools Rogowski probes are
compatible with all of the Teledyne Test Tools
Oscilloscopes as well as the Teledyne LeCroy
Oscilloscopes.
The Teledyne Test Tools Rogowski probes have a
simple connection requirement of a BNC input with 1
MOhm impedance. These probes will therefore work
with the majority of oscilloscopes in the market.
The probes can be made even more useful by using
your Oscilloscope’s Attenuation function to re-scale
the Channel vertical range.
Application Fields
