The Qualtek QFWB-5-12-US01 is a versatile AC/DC wall mount adapter designed for ITE (Commercial) applications. It delivers a stable 12V output at a maximum current of 500mA, providing a total power of 6W. This adapter operates with a universal input voltage range of 100-240VAC and meets Energy Efficiency Level VI standards, ensuring reduced energy consumption.
The unit features a fixed blade NEMA 1-15P input connector and a standard 2.1mm I.D. x 5.5mm O.D. barrel output connector with a positive center polarization. The cord length is approximately 59 inches (1.50m). Its compact dimensions of 39.2mm x 24.0mm x 42.0mm make it suitable for space-constrained designs. The adapter operates within an ambient temperature range of 0°C to 40°C and includes essential output protections such as short circuit and over current protection.
Designed with a switching flyback topology, the QFWB-5-12-US01 ensures reliable power conversion. It complies with EMI standards EN55022 Class B and FCC Part 15 Class B, as well as harmonic current and EMS immunity standards. The MTBF is rated at 50,000 hours under specific conditions, indicating good reliability for its intended applications.
