CA48S12-40

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.
