THE CA SERIES FROM WALL INDUSTRIES

The CA Series of single, dual and triple output DC/DC con-

verters 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.
