When it comes to working with high current and high voltage circuits or systems, it’s always best practice to try to isolate the control interface from the potentially deadly power ratings that may be used to operate heavy-duty Components like motors, heating elements and other high-draw parts. However, this is not always easy, and when dealing with very high-current (dangerous) systems, you often have to create a secondary circuit that interacts with the high-power circuit – but without ever physically connecting the two so as to endanger the operator.

This is where the true benefits of DC-DC isolating Modules like the Recom RFB 1W Isolated DC-DC Converter come in handy, as they offer a means to control high currents with a separate, isolated control circuit, allowing for safe operations of systems which could be potentially dangerous to any users who are unfortunate enough to experience the full force of a short circuit. Furthermore this also helps to maintain an extremely precise voltage level for extremely sensitive voltage matching applications. This is quite necessary for some highly sensitive components, of which a slight power surge or power drop could damage them, even if the supply you’re using doesn’t quite offer the perfect output stability that your project or system might need.

This RFB DC-DC Converter is relatively simple, and features a 5V In 5V Out 1:1 ration conversion, capable of 200mA output for a total of 1W power. And while this may seem rather negligible when dealing with systems that operate in the hundreds or thousands of volts, it is actually just enough to be able to perform a good range of functions, from controlling Relay Modules to performing sensor adjustments when necessary. It is very commonly used alongside the ISO1050DUB Isolated CAN Transceiver, but can realistically be used for a good range of different isolation and precision voltage matching applications.
