Help identifying alternative component Power Board

radurotaru · 2024-08-20T13:53:53-0700

Hi, I would like to get some help in trying to obtain a Datasheet or a suggestion for an alternative part of a Power Board PCB.

Part number HM00-05015LF

Marked as component T1 in the following diagram:

By the looks of it might be a Transformer. I could not find a datasheet anywhere. I got in contact with basically all the Chinese suppliers and no one has a datasheet.

It is a current transformer. ( CT ) It measures current in the load and makes a voltage.
It looks at the current in your heater, as the current passes through J7--J6.
AT J24-18 to 19 there is a voltage of 50mV/1A. or 500mV/10A or 1.5V/30A.

Can not find an exact match. Looks like 50:1 transformer with a max current of 15A.

Can you still get at the small wire coming out of the plastic? (not the wire in the hole in the middle) Maybe we can repairer it. Looks like the PCB is damaged also. Maybe too late to fix it.

Thanks for the help, I am afraid the component itself is toasted and needs replacing. I don't need an exact replacement I can solder some additional legs. Thanks for the info!

If nothing else, since you say you don't need an exact replacement, you can extract a current transformer by destroying any ordinary GFCI outlet and pulling out its transformer. I've used them in projects before. Same setup as what you have, a many-turn secondary around a single wire primary.

Here's one being modified:

This one had 2 secondaries; could use just one or wire them in series as needed.
