Important Characteristics When Selecting Brands for Isolated Converters

Understanding what makes a good isolated converter brand and what makes a bad one is necessary before looking into particular brands. Whatever your industry is, these factors will help you identify trustworthy brands:

To start, long-term R&D is necessary for success. Because of how quickly power supply technology changes, R&D that lasts over a decade shows that a brand understands insulated converters better than their competitors. For instance, brands that have solved problems that most converters cannot withstand extreme temperatures or withstand water, and then solved other real-world problems. You know that isolated converters that have weather resistant converters will be around to help in case of potential fragile situations or high temperatures.

Another positive aspect is having a diverse product range. Projects vary from one another and so do the adapters, for example, an industrial machine might require a high-voltage isolated converter whereas an RV needs an adapter that is compact and waterproof. The most reputable brands have hundreds of converters to satisfy these demands. The most reputable brands have over 500 types to choose from, including isolated DC- DC converters and ones used in waterproof RC toys. Having so many options makes it less likely to increase the risk of specs of fits adapters.

Global recognition should not be underestimated as a helpful resource. If a brand’s products are used in over 130 countries, it is a sure sign that it meets international standards with regards to quality and safety.
