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.
