These converters use a full bridge power train to provide isolation and step down. These units will provide up to 300 W of output power from a nominal 48 Vdc input. These units are designed to be highly efficient and low cost. Features include remote on/off, over current protection and under voltage lockout. These converters are provided in an industry standard eighth-brick package. Part Selection Output Voltage 9.6 V Input Voltage 38 Vdc-55 Vdc Max. Output Current 40 A Max. Output Power 300 W Typical Efficiency 96.5% Model Number Active Low 0RCR-40S10L Model Number Active High 0RCR-40S100 Notes: Add "G" suffix at the end of the model number to indicate Tray Packaging.
