Other Parts Discussed in Thread: DCH010515S

Hello,

can I use DCH010515S for the gate driver floating supply for MOSFET (400V). In Data Sheet you are written that module has UL60950 Certificate.   

Thanks

    Hi Anton:

    The DCH is not designed for continuous motor gated drivve and or IGBT applications where voltages are greater than 42VAC ro 60VDC peak .

    The UL/IEC60950 E199929-A2 CB3  1DCH01  SELV statement :

    The 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 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 coated. The UL listing, E199929-A2 , voltage limits are SELV or 60VDC continuous or 42V transient peak.
