ISOLATED DC/DC CONVERTERS 48 VDC Input 9.3VDC/36.5 A Output, 1/4 Brick 07CM-38S10L RoHS 5 Compliant • Industry standard quarter-brick package • Up to 300 W at 95% efficiency • 1500 V isolation • Safety Agency Approvals Rev.C Description The 07CM-38S “Cimarron” Series are isolated DC/DC converters that operate from a nominal 48 VDC source. 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 54 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 quarter -brick package. Part Selection Output Voltage 9.3 Vdc Input Voltage Max. Output Current 36.5 A 48 Vdc Max. Output Power 300 W Typical Efficiency 95% Model Number 07CM-38S10L Notes: 1. Add “G” suffix at the end of the model number to indicate Tray Packaging. 2. All part numbers above indicate RoHS 5. Change the second letter "7" to "R" for RoHS 6 part numbers.
