QBE75/100W -Highly Efficient 75W and 100W Quarter-brick DC/DC Converters- Synerdyne / P-DUKE

Train Control and Management Systems (TCMS), Passenger Information Systems, Lighting systems in train cars, Air conditioning and ventilation control units, Robotic arms and industrial robots, Programmable Logic Controllers (PLCs), and Human-Machine Interfaces (HMIs)

Developed for industrial and railway applications, they achieve high conversion efficiency averaging 92%, reducing power loss, supporting wider operating temperatures, and enabling smaller heatsink designs.

The series features a wide 4:1 input voltage range of 9–36 Vdc, 18–75 Vdc, and 40–160 Vdc, making it suitable for various global power systems. Multiple output voltages are available, including 3.3, 5, 12, 15, 24, 28, 48, and 54 Vdc, with adjustable output from +10% to -20% via an external resistor.

To ensure reliable and safe operation, the QBE series includes over-current protection, output over-voltage protection, continuous auto-recovery short-circuit protection, input under-voltage lockout, remote sensing, and remote ON/OFF control. It complies with major industry standards such as IEC/EN/UL62368-1, EN50155, and EN45545.

Designed for harsh railway and industrial environments, the QBE series meets MIL-STD-810F and EN61373 standards for vibration and shock resistance and can operate at altitudes up to 5000 meters. These features make it a highly reliable and stable power solution for rolling stock and industrial electronic equipment.
