0RCM-36S10L

ISOLATED DC/DC CONVERTERS 48 VDC Input 9.4 VDC/36 A Output, 1/4 Brick 0RCM-36S10L • • • • RoHS Compliant Industry standard quarter-brick package Up to 300 W at 96% efficiency 1500 V isolation Safety Agency Approvals Description The 0RCM-36S “Cimarron” Series are isolated DC/DC converters that operate from a nominal 48 V DC 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 9.4 V Input Voltage 48 V Max. Output Current 36 A Max.
