OWA-90E-12 application field and working principle
AC DC Desktop, Wall Adapters
OWA-90E-12 is a type of AC/DC desktop wall adapter. It contains both isolated and non-isolated types, which provides users both direct power conversion and the isolation protection. The adapter has a wide input range from 90VAC- 132VAC or 180VAC-264VAC, and its output voltage is 12V with current rating ranging from 0.5A to 10A.
Application Fields
The OWA-90E-12 AC adapter can be widely used for indoor uses, including household products such as lamps, radios, etc., and for commercial uses, such as industry equipments, computers, digital products, etc. The fanless design and metal enclosure of the adapter allows it to withstand most of the outdoor environment.
Working Principle
The working principle of the adapter is relatively simple. The AC power is directly converted by the power adapter to the DC voltage using a rectifier bridge. The rectifier bridge contains diodes, which convert AC to DC. Then, a switching power supply is used in order to regulate the output voltage. A switching power supply mainly contains two parts: a transformer which converts AC power to the low voltage, and a transformer which regulates the output voltage.
Finally, the voltage is regulated by a switching regulator, which ensures that the output voltage is accurately and reliably maintained. The switching regulator consists of a feedback control circuit, which provides feedback signal to regulate the output voltage, and a control transistor, which act as the switch to regulate the output.
Advantages
The AC/DC adapter of OWA-90E-12 have the following advantages:
- Wide input voltage range
- High efficiency
- Excellent line and load regulation
- Fanless design and isolation protection
- High reliability
- Low standby power consumption
Conclusion
The OWA-90E-12 AC/DC adapter has been well received by users due to its wide input voltage range, high efficiency, and excellent line and load regulation. It is an ideal choice for many household and commercial applications.
