| CA SERIES 25 TO 40 WATTS - CA SERIES Ultra Wide Input Voltage Range, Low Profile 25 TO 40 WATTS FEATURES * Ultra-Wide Input Voltage Range (4:1) * LC Input Filter for Low Reflected Ripple Current * Regulated Outputs * Thermal Shutdown with Auto-Recovery * Current Limiting Short Circuit Protection * 500VDC min. I/O Isolation * Industry Standard Package and Pin-Out * Industrial temperature grade also available 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.
