Guildline Instruments Limited 500 Amp, Precision DC Current Shunt. 0.5 mOhm , 25 Watts Ambient Air. 100 Watts when used with 92310 Option (92310 Priced separately)
The Guildline Instruments 9230A-500 is a high-precision DC current shunt designed for accurate measurement of 500 Amps. It features a nominal resistance of 0.5 milliohms and is rated for 25 Watts in ambient air. When used with the optional 92310 Heat Sink (sold separately), the power rating increases to 100 Watts, allowing for higher current measurements without compromising accuracy. The 9230A-500 is part of the 9230A Series, which is engineered for laboratory and calibration applications requiring low resistance and high stability. The shunt is constructed with materials and techniques that ensure long-term reliability and minimal temperature coefficient, making it suitable for demanding metrology environments.
