THE CA SERIES FROM WALL INDUSTRIES
The CA Series of single, dual and triple output DC/DC converters performs over an ultra-wide input voltage range (4:1), providing indefinite short circuit and overvoltage protection. Without a heatsink, the CA Series’ design technology allows for up to 40 watts output power from a 3.0 x 3.0 x 0.40” case. These current mode control forward converters are designed for improved transient response and reduced stress on switching components.
