It is designed with the attached schematic diagram, but not enough power.
The supplied power supply is 36 VDC.
If the input current exceeds approximately 2.5 amps, fault signal is output.
Test conditions are the 3Vp-p/800Hz signal input.
I think it's not a temperature problem because the heat sink is designed properly.
Also, the fan is mounted and operated.
Let me know what we're missing.
