Device: Telemechanique Industrial Motor Soft-start controllerOrigin: Gift / Acquaintance
Reason for teardown: That's why I got it
Impressions: Obviously something went horribly wrong inside this thing and the pins of the high current relays prompty evaporated when it happened. It contained some fairly useful components that survived the ordeal. The large heatsinked modules are POWERSEM 100A (that's one hundred amperes) dual thyristor(SCR) modules perfect for heavy duty AC power controllers or solid state relays (which I ended up making out of them). The mains tranformer also found a new home since in a garage door opener remote control box.
That's a PIC.. I can probably use that too for something (not really.. I do AVRs but too lazy to do anything with those even nowadays..).
Another evaporated pin
Mains and pulse transformers
