| ISOLATED DC/DC CONVERTERS 48 VDC Input 9.4 VDC/70 A Output, 1/2 Brick 0RCN-70S10L * * * * RoHS Compliant Rev.A Industry standard half-brick package Up to 500 W at 96.5% efficiency 1500 V isolation Safety Agency Approvals Description The 0RCN-70S "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 500 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 quarter-brick package. Part Selection Output Voltage 9.4 Vdc Input Voltage 48 Vdc Max. Output Current 70 A Max. Output Power 500 W Typical Efficiency 96.5% Model Number 0RCN-70S10L Notes: 1. Add "G" suffix at the end of the model number to indicate Tray Packaging. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
