A friend has managed to break his DZB200 inverter made in 2010.
Two of the output FETs/IGBTs are shorted and the fusable input resistors are burned open circuit.
This tripped the main breaker. Whether this was the original fault or whether somethining else tripped the breaker is yet to be determined.
It's driving a router spindle.
My question then is, are spares available for these, specifically the PCB with the rectifier and output drivers?
In the meantime I've fitted an AT1 VFD, which works, mostly, but I'd like to repair the old one rather than have it go to landfill.
