0RCR-18S08L

ISOLATED DC/DC CONVERTERS 48 VDC Input / 140 W Output , 1/8 Brick 0RCR “Cimarron” Series • • • • • RoHS Compliant Industry standard eighth-brick package Up to 140 W at 95% efficiency 1500 V Isolation Remote On/Off Low Cost Description The 0RCR “Cimarron” Series are isolated DC/DC converters that operate from a nominal 48 VDC source. These converters use a half bridge power train to provide isolation and step down. These units will provide up to 140 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 8V 12 V Input Voltage 48 V 48 V Max. Output Current 18 A 12 A Max.
