Maximum Load Inductance
While de energizing inductive loads, energy has to be dissipated in the BTS 6142D. This
energy can be calculated via the following equation:
In the event of de-energizing very low ohmic inductances (
equation can be used:
The energy, which is converted into heat, is limited by the thermal design of the
component. For given starting currents the maximum allowed inductance is therefore
limited. See
