help needed with equivilant relay

[fandtm666]

i have a vfd that has popped a relay and for the life of me cant find the same
one in auss. what would be an equivalent for it .

[wotnot]

[fandtm666]

cheers ill have a look at it

[Reschs]

PC 1 and PC 2 do not look healthy.

Is that damage to relay from the contacts or from the resistor leaning against it ?

What current is it switching ?
Altronics do a 7.5 Amp one.

[fandtm666]

damage was from resistior leaning aganst it .

is annoying because this was a spare unit i have had sitting in the cupboard
and was setting it up for a bench router setup so no warranty.

[wotnot]

They're rated at 16A, 24v coil, NO ....I got the cross reference from their own site actually --> ... so the SCHRACK part is a direct fit replacement.

RS actually carry them -->>

[fandtm666]

thanks mate

[wotnot]

I should've figured earlier RS would have then (or equiv), seeing as they have manuf. contracts in CN B)

As the damage is from the resistor, is it only cosmetic ? Most likely.

The damage to PCCI and 2 would worry me more, or this just a problem with the photo.
Both appear to be extremely damaged.

ill suss out what they are and replace all 3 while i am at it
pretty sure they are P701 optocoupler

That's just a thick layer of conformal coating =)

Nah, just kidding...top one looks cracked/blown ...possibly indicates another fault =/

edit: this is a HUAN YANG 2.2kw VFD/VSD ?

yep thats the sucker

[wotnot]

Yeah, ok..... I'd be tossing it (if no warranty =) Seeing that opto couplers fried, means it's blown it's mosfets on that phase, so they'll need replacing, you'll have to also check the snubber networks are ok for those, then you'll have to check the lower power DC hasn't been taken out by the optos blowing.

These are a ~$160 unit ; even if I repaired them all the time, I know I can't economically repair them because time & parts exceeds cost of new unit. That simple....and because they're cheap CN shit, this'll happen again.

yep been reading a bit more last night and checked some circuits and tracks and i will just toss it
Ill just keep the front panle because its fine and can use it if needed on my working one.They
are a bit more that $160 but not work the dramma considering it has to run a spindle at upto 24k.

thanks for the input
