Description
An assembly consisting of 8 channels shuts down at 85°C
heat sink temperature. The remaining 24 stay active. With a
Hysteresis of 25 ° C, i.e., at 60 ° C, the affected group turns
on again. Each MOSFET bridge on a module has a
shutdown threshold of 120 ° C. In this case, only two
channels are affected, and the other 30 remains active.
If the polarity of the signal changes not for more than a
second, the affected channel switches off and restarts
again after a few seconds.
The affected channel is switched off when the maximum
current of 15A is exceeded. Recovery time is about two
seconds.
The amplifier works unconditionally stable at low
impedance as long as the maximum current is not
exceeded.
