Precision Shunts - 0.1 to 10 Amp

HIGH ACCURACY
0.1 A TO 10 AMPS
LOW TEMPERATURE COEFFICIENTS
LOW POWER COEFFICIENT
IMMUNE FROM CONNECTION ERRORS
DC AND AC USE
RUGGED

The CS series precision current shunts are designed for the most demanding measurement applications. These shunts provide excellent long term stability and very low temperature and power coefficients. Designed for laboratory use, they are rugged enough to be installed in environments subject to wide variations in temperature and to vibration or shock.

Every shunt is provided with ISO 17025 accredited calibration through full rated current.

The CS-0.1 to CS-10 shunts exhibit close AC conformance to DC values. AC/DC difference is estimated to be less than 0.01 % to 1 kHz.

The temperature coefficient of resistance is less than 5 ppm / °C, which minimizes the change in resistance due to self heating under power.

Connection errors, common in many shunts, are minmized by the internal bus structure.Connections are via gold plated binding posts, which accept bare wire, banana plugs and spades.

Standard models are listed, but other Amp/Volt combinations are available.

For the highest precision applications, a 100 ohm RTD can be bonded to the shunt element, and full current / temperature characterization can be provided. Please see the Temperature Option for an example of this characterization. Type T or thermistor sensors are also available.

All Ohm-Labs' shunts have a 2 year warranty.
