Part Number: DCH010505D

Customer would like to get related Safety doc including circirtry, Transformer SPEC and safety doc..

Please help to support such data for parts approval.

BTW, we've found a related doc as enclosure. However, it looks it was made 8 years ago. is there any update one? Thanks.

    Brian:

    DCH01  external continuous voltage difference limits are defined as voltages as measured between VIN (-) and Vout (-) ground). The converter is designed as ground fault isolation device. It is not designed to operate with a continuous voltage isolation barrier at greater than 60VDC. The 3KV isolation 1 second test validates only the magnetic coating separation between primary and secondary transformer wire.

    The maximum potential difference ( Vin(+) to Vout ground ) as referenced to  a common ground is limited to continuous 60V DC or 42V Peak  transient between Vin(-) and Output ( ground) . . The primary and secondary transformer wires are coincidental and contact each other separated by magnet wire over-coating. The transformer wires are single coating material and not dual/reinforced coated insulated wire. . The UL listing, E199929-A2 , voltage limits are SELV or 60VDC continuous or 42V transient peak..
