The QM48T14120-NBB0G is a DC-DC converter from Bel Power Solutions' QM-Series. It accepts an input voltage range of 36 to 75 VDC and provides a regulated 12 VDC output at up to 14 A, delivering 168 W of power. The converter achieves high efficiency of 92% typical, eliminating the need for a heat sink in many applications.
Key features include remote on/off, overcurrent protection, overvoltage protection, overtemperature protection, undervoltage lockout, and remote sense. The output can be trimmed from -20% to +10% of nominal. The converter supports start-up into pre-biased loads and requires no minimum load. It operates at fixed frequency and offers a paralleling option for higher power.
The quarter-brick package measures 58.4 mm x 36.8 mm x 9.1 mm and weighs 31.5 g. Mounting is through-hole. Safety approvals include UL60950-1, CSA60950-1, EN60950-1, and IEC60950-1. The converter is designed for telecommunications, data communications, wireless communications, and server/workstation applications.
