Thurlby Thandar... not a happy bunny

(1/6) > >>

Baliszoft:
My voltcraft VLP series 60V power supply has just died (and since i did not have time neither intention to fix it) i ordered a TTI PL601 bench supply from farnell. I was hesitating on getting a tektronix one (for nearly the same price), but i liked the TTI one better (due to its features and rotary knobs). The supply arrived in a day (as everything from farnell), but when i opened the box and took the thing out, something was terribly rattling in it. I managed to get the thing(s) out via the air vents by rotating and shaking the supply (i did not open it for warranty reasons). A clip for the heatsink came out in two pieces. It looks like it was on a rectifier lookalike package, which still has one clip left on it, BUT it is also cracked. Before you would ask, no there is no damage on the packaging, not even a small dent.

I went for TTI, because i thought it was something high quality. I am definitely not a happy bunny!

What would you do? Would you send it back under warranty, or would you request two of these clips from TTI and fix it by yourself?

Zad:
To be honest, metal fatigue in a component like that is just not something you test for when building equipment. That clip will have had a fault in since the original steel was rolled, exacerbated when the clip was fitted, and then failed at some time after that. You can only go so far in testing supplied components.

I would drop TTI an email, asking them if repairing it would invalidate the warranty, and if not then could they please send a clip.

Yes, i just did exactly the same thing. Since it is friday late afternoon here, i guess i will have to wait until monday for their answer.

... but two damaged clips in the same unit  :o  ::)

I would have got Farnell to replace it next day and collect the faulty one.

Definitely warranty, quite likely something else is causing these clips to crack, perhaps something under the semiconductors such that the clips get much more tension. That would mean you cannot trust the rest of the thermal system either... No need to solve their problems, as a matter of fact, if they take quality seriously, they will want to investigate themselves anyway.
