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

The CS-20 and CS-50 exhibit close ac conformance to dc values. AC/DC difference is estimated to be less than 0.02 % at 1 kHz.

Ohm-Labs' custom heat treatment reduces the temperature coefficient of resistance to less than 5 ppm / °C. This minimizes the change in resistance with applied power.

Connection is made via high quality, gold plated binding posts, which accept bare wire, banana plugs and spades. Internal design has eliminated connection errors common to many other shunts.

Standard 20 and 50 amp models are listed, but other Amp/Volt combinations are available. This housing style is recommended for power (I2R) up to 25 watts.

All shunts are supplied with ISO 17025 accredited, NIST traceable calibration through full rated current.

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.
