ONNECTING THE
BAT-S 1000 1U
SENSOR FOR VOLTAGE MEASUREMENT
For voltage measurement the 2-pole MicroFit-connector is used. The two pins are shorted
internally. The voltage measurement uses one side of the shunt as reference (see
3.2.2.1).

For further and detailed information on the BAT-S1000 1U refer to the product
specification by ACTIA I+ME GmbH.
The maximum current depends on the mechanical position and the heat dissipation
conditions. The high current cables connected provide a heat sink for the shunt. The
connections have to be made with a minimum contact resistance. The cable have to
be over dimensioned to achieve proper heat dissipation.
The inner heat resistance is approx. 2 K/W, the resistance is approx. 25µ
Ω
and the
nominal power is approx. 15W. Ensure that under worst case operating conditions a shunt
temperature of 85 °C is not exceeded.
