Attempting repair of a Secop Electronic Unit for BD35 compressor, company formerly known as Danfoss.
Model 101N0500 for 12/24V BD35 compressor
Replacement unit is $150 plus postage  ^-^

Board drives the BLDC motor in the compressor, and has 3 output mosfets, two of which are blown.
Surviving mosfet says
IRF P222J
8DFA
F7343
It's a SOIC-8 package
Cannot find any datasheet for this International Rectifier part.

Not found anything yet on power draw, bar a data sheet that recommends the main battery switch be rated to 20A.

Only advice I've found on this unit is to replace it with a 48V BLDC controller for ebike, which then needs 48V to run to compressor at the same speed.

Do somebody perhaps have a  circuit diagram of the Danfoss Secop 101N0500 unit.   

I do have about 10 units all with problems on the mains side of the switch mode psu. The 12/24V side hardly goes faulty.

Best regards.
Johann Prinsloo.

Hi Johann
Did you come right with a cct diagram for the  Danfoss Secop 101N0500 unit? I am also sitting with a fridge which seems like this unit is faulty. I am very rusty on electronics but I am willing to try to fix the unit in order to get my fridge going again.

If you can assist I would really appreciate it. My mail add. is inus.jordaan@vodacom.co.za
