If the current divider is wrongly calibrated, the switch-off current may
not be reached. In this case there will be no safety switch-off! Due to
the electromechanical uncertainties the current divider should only be
used in prototypes and testing.
3.2.2. BAT-S 1000 1U SENSOR
The Current sensor BAT-S1000 1U is shunt based sensor with isolated CAN interface. Air
and creepage distances provide isolation up to 1500 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: ±1000A (rated); ±1200A (max.)
Range voltage: ±1000V (rated); ±1200V (max.)
3.2.2.1 SYSTEM INTEGRATION
The sensor may be connected either in the positive current path or in the negative path as
well. The Ground Level of the voltage potential is the shunt.
