• Reliable protection: with its over-voltage, over-current and short-circuit protection
• Efficiency: high efficiency and low power consumption
• Reverse-polarity protection: FWE050048B-10B with reverse-polarity protection, providing more safety.
• Wide voltage compatibility: it is available from AC 100V-240V.

Working Principle

The FWE050048B-10B is a power adapter equipment that converts AC into DC to meet the expected voltage. First, AC power is converted to DC power at the input end of the adapter. Then some electronic components (such as coils, capacitors, resistors, inductors, and the like) will be used to step-down the voltage so that the DC voltage can reach the required level. Finally, the DC output voltage will be used in electronic products.

The FWE050048B-10B adopts a hysteretic control system to adjust the output voltage. The voltage drop between its two ends is sensed and then the current frequency is changed accordingly through the comparator and the hysteretic control loop, so as to maintain the stability of the output voltage. The DC voltage output from the adapter is relatively stable, but it may still produce low-frequency fluctuations, so an additional filtering circuit (such as capacitors) is used to filter the small-amplitude, low-frequency fluctuations.

Conclusion

The FWE050048B-10B is a reliable and efficient AC DC desktop, wall adapters. It is widely used in LED lighting, POS machine, medical devices, printers, speakers, scanners and so on, and supports an input voltage from 100VAC to 240VAC. Moreover, it adopts a hysteretic control system to adjust the output voltage, and provides an additional filtering circuit for voltage fluctuations. As a result, the FWE050048B-10B can provide users with a stable and reliable power output.
