Samlex 100W Isolated DC-DC Converter, 20-35V Input

The Samlex IDC-100B-12 is a fully isolated 100W DC-DC converter giving a regulated 12.5V from a 20-35V input, at up to 8 amps.

Full isolation separates the source and load circuits electrically, which is required rather than preferred in some installations. A metal hull, a bonded system or sensitive equipment sharing a ground with a noisy source are all cases where a non-isolated converter causes problems that are hard to trace afterward.

Fold-back current limiting protects the unit under overload rather than simply shutting down. It reduces output as the fault develops, which lets a marginal overload be diagnosed rather than producing an unexplained dropout.

Further safeguards cover short circuits, overheating and reverse polarity. Reverse polarity protection matters most during installation, which is exactly when a connection error is most likely. Explore more DC-DC converters and power supplies.
