Description
In most electrical systems both 24 VDC and 12 VDC equipment is used. WhisperPower Switched Mode DC -DC converters take a particular voltage, for example 24 VDC, and convert it in to another DC voltage, for example 12 VDC. The Switched Mode technology ensures minimal energy loss and high output.
