    Hi all,

    I got a Schneider PowerLogic PM5500 which work threw out. Unit blew up due to poor switchboard installation by supplier. Typically this is a $1000 meter.

    I have taken it and found the rectifier diodes shot, so there's a good chance I might be able to salvage this.

    The rectifier diodes appear to be Bourns CD214A-R12000, 1A rated, 2000V breakdown voltage.

    Tested with millimeter diode tester, 3 of the 4 diodes appear dead. One of them was around 0.6V forward, but I am going to replace them all.

    Can anyone help identify the Pulse PA3569NL package? doesnt appear to have any burn or smells.

    Given the size and Pulse's range of products, my guess is it's a transformer, probably for isolation. Is it through hole mounted, and how many pins are there?

    Tried some 1N4007 diodes and it just shorted on power up again, guess its bin time!
