ICE ISB current sensors combine high performance and easy bus bar mounting in a cost effective solution.

Press Release from ICE Components, Inc.

ICE has introduced the ISB family of current sensors for use in a wide range of bus bar mounted  applications.  The sensors measure both DC and AC current  from values as low as 50 A up to 670A.  Options for the new sensors include faster response time, temperature output, reference output and a  standard connector or lead wire.  

All ISB models feature a unique bus bar mounting method to simplify installation.  The sensor  separates into two halves that easily clip around the bus bar. The small size of 28 mm L x 26.4 mm W x  19.8 mm H also helps the sensors to fit seamlessly into many difficult installations.  There is no need to  create extra bends or breaks in the bus bar to accommodate a traditional current sensor with a solid  diameter.  

There are two connection options for the ISB current sensors.  Customers have the option of a  connector output that features a creepage distance of 8.5 mm.  The second option is UL3239, 3 kV  rated lead wire which expands the creepage distance to over 140 mm.  Custom lead wire lengths  and/or customer specified connectors can be ordered.  Both options have a CTI (comparative tracking  index) of 600 and withstand an isolation test of 4.3 kV rms.  

Other features include the choice of an optional temperature output or a reference output.  The  temperature output can be used for compensation over a temperature range.  The reference output is  commonly used to drive an op­amp circuit for easy increased output flexibility.  

The sensors are available with either a standard 8 uSec response time or a faster 3 uSec response  time.  The 3 uSec model (ISB­XX­A­8XX) is rated for a 200 kHz bandwidth and is suitable for higher  frequency applications.  The 8 uSec model (ISB­XX­A­6XX) is rated for a 90 kHz bandwidth.  

Both models operate off an input voltage of  5 VDC and provide a 0.5 to 4.5 VDC output voltage that is  ratiometric to the input.  They conform to the EN50178 safety standard and the EN61000 EMC  standard and are recognized for an operating temperature range of ­40 to +85 degrees C.
