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.
