3.2.3. IVT-B SENSOR
The current sensor IVT-B by Isabellenhütte is a shunt sensor with isolated CAN interface.
Air- and creepage distances are sufficient for 500 VDC.
Additionally the sensor has a quasi-synchronous voltage measurement interface and an
internal temperature measurement. The CAN2 interface of the MASTER is reserved for this
sensor.
Range current: ±320A (1500 A for 1 second)
Range voltage: ±620V
3.2.3.1 SYSTEM INTEGRATION
The sensor may be connected either in the positive current path or in the negative path as
well.
3.2.3.2 CONNECTING THE SENSOR TO MASTER
Molex MicroFit 8-pol (view of the connector at the device)
CN104 Tyco 9-pol
IVT-B-signals OCS und SYNC are not used. Shorting the CAN-T-lines provides a 120Ω-bus
