Trigger Output Monitor
The trigger output signal is generated with an integrated, isolated Rogowski coil and
provides an ultra fast galvanically isolated signal. The signal shape is proportional to the
derivative of the load current. It can be used for a current response triggering signal and
has no delay to the load current. Combined with an integrator it is possible to use this
signal for a galvanically isolated current monitor.

Cooling
The driver is base plate cooled only. Please assemble the entire unit to a heat sink which is
capable to take out the heat.
The heat sink is suitable if the system temperature does not exceed the maximum operating
limits.
