Internals and Electronics

Inside we find a two heatsink design and the usual two-transistor forward converter. The primary heatsink is a little larger in volume than the other since it needs to dissipate more heat from the hotter components attached to it. On secondary side only the +12 V rectifiers are connected to the heatsink as there are DC-to-DC converters for the smaller outputs. The main cap is made by Panasonic and rated at 105°C. In Win uses different suppliers for their caps, a few from Samxon (GK) can be found at the outputs. Both the PFC transistors as well as the half-bridge transistors (K15J50D) got a large semiconductor case to improve cooling. Moreoever the EMI filtering consists of all necessary components including a MOV.

    No matter what the donation, support or mention is ANY help is appreciated and all adds up.
    In-Win donated a power supply for a Custom PC Mod/Build that auctioned to pay for the recycling, refurbishing and reclaiming of scrap by disabled veterans for disabled veterans.
    This one item teamed up with a few others build a customized computer called Purple Heart - MERIT.
    That auctioned off and all funds donated to PCs4VETS.
    PCs4VETS used some of the funds to sponsor a E-WASTE Event in San Diego in November 2012.
    The E-waste was a success, Veterans took the waste and broke it all down reclaiming metals and rare earth compounds for recycling. $1,000 of dollars worth in the semi load.
    Those funds and the remaining funds paid to refurbish 100's of laptops. We have the cost down to $20/laptop, from donation to veterans door.
    1 simple donation lead and built up to 100's of tools put into the hands of needy veterans and families.
    It does not have to millions in donations to change the world, a life, save resources or even a life.
    Thank You IN-WIN for helping me change the world,
    Al Shuryan
    Co-chair PCS4VETS Advisory Council
