Isolated DC-DC Converters

An isolated DC-DC converter keeps its input circuit and its output circuit electrically separate. That separation is the whole point of the category. Where a non-isolated converter shares a common ground between input and output, an isolated converter breaks that connection, so noise on the input side does not travel to the output side, and a fault on one side does not drag the other side down with it. For equipment that must keep running cleanly in electrically noisy surroundings, that separation is not a luxury, it is the requirement that decides the purchase.

The category on this site lists three conversion options: 35 to 100 volts to 5 volts, 35 to 100 volts to 12 volts, and 35 to 100 volts to 24 volts. Those three options are category-level listings, which means their voltage conversions are stated and no further performance figures are claimed for them here. A buyer who needs a current rating, a power rating, or a dimension for one of those three options should ask through the inquiry form, where the correct figures for that option can be confirmed.

One line in this category carries a full published specification sheet and has its own detail page: the WGI10 isolated converter series. Its detail page states an input range of 36 to 90 volts, a 12 volt output, a 10 amp output current, 120 watts of output power, synchronous rectification, electrical isolation between input and output circuits, and a footprint of 110 by 70 by 23 millimetres. Those figures belong to the WGI10 series alone and are not shared with any other converter in this category.

The stated application areas for the WGI10 series are telecommunication equipment, industrial control, artificial intelligence, consumer electronics, and alternative energy. Those are the applications named on the product's own detail page, and they explain why isolation matters in practice: a telecom cabinet, an industrial controller, or an energy system all sit in environments where ground noise, surges, and differing ground potentials are everyday problems rather than rare events.

Choosing an isolated converter starts with the voltage conversion, then moves to the current and power the load actually draws, then to the physical space available. A converter that fits the voltage but cannot deliver the current is no use, and a converter that delivers the power but does not fit the enclosure is no use either. The selection guides on this site work through those questions in order, and the detail page for the WGI10 series gives the numbers needed to answer them for that series.

For the other two conversion options in this category, the honest route is the same as for every category-level listing on this site: state the conversion, describe the use, and confirm the remaining figures during the inquiry. Certificates are available upon request, and before ordering, confirm quantity, price and delivery time.
