Trace SW2612E Problem

intelmacs

Hi everybody,

I recently purchased a Trace SW2612E off of ebay as spares or repairs in hopes of fixing it. The guy I bought it off said it had powered his home for 15 years until one day the lights went out and there was a humming sound and heatsink overtemp displayed. Anyways I took it home connected a battery, it powers up fine however when I press invert the inverters transformers pulse with loud 50hz ish hum. It sounds like it's trying to inverter, pulling to much current the tripping and starting the process again. I opened it up there isn't any obvious problems, all the MOSFETs seem fine. I'm unsure on how to proceed.

Many thanks,

Matthew

Welcome to the forum Matthew.

All I can say is that I hope you didn't pay much for 20-year-old broken technology that no one repairs anymore. Yes, it's about that bad.

There are some places that offer to repair the old SW's but it's of questionable value as it will still be an old inverter waiting to fail again at a moments notice. It's a shame too because they were one of the best designs. Really good ... in their day. Like me.
