0RQB-C0U12LG

The 0RQB-C0U Series are isolated DC/DC converters that operate from a nominal 48 VDC source. These units will provide up to 100 W of output power from a nominal 48 VDC input. These units are designed to be highly efficient and low cost. Typical efficiency of 12 VDC output at 48 VDC input and full load is 91%. Features include remote on/off, over current protection and undervoltage lockout. These converters are provided in an industry standard quarter brick package. • • • • • • • • • • • • • • • • • • 48 VDC Input 12 VDC/8.35 A, 5 VDC/20 A, 3.3 VDC/25 A, 1.2-2.5 VDC/30 A Output Isolated High Efficiency High Power Density Low Cost Input Over / Under Voltage Lockout Fixed Frequency (285 kHz) Active Low/High (Option) Output Over-Voltage Shutdown OCP/SCP Over Temperature Protection Remote On/Off Output Voltage Trim Positive/Negative Remote Sense Basic Isolation Approved to UL/CSA 60950-1 Approved to UL/CSA 62368-1 (pending) • • • Networking Computers and Peripherals Telecommunications 0RQB-C0U Series 2 MODEL NUMBER ACTIVE HIGH MODEL NUMBER ACTIVE LOW OUTPUT VOLTAGE INPUT VOLTAGE MAX.
