DT12PW190B

Application Field

DT12PW190B is a AC/DC Desktop, Wall Adapters, which can be widely used in telecom, computer, personal electronics, home appliances, and industrial fields and so on. DT12PW190B is an energy-efficient product that has CE, EMC, FCC, TUV, UL and CUL safety approvals, and is RoHS-compliant, making it ideal for use in the global market.

Working Principle

DT12PW190B is a simple and efficient design, and the electricity is transferred from the electrical outlet through the PC board to the power output connector. Through the alternating current received from the electrical outlet and into the transformer, the voltage will be stepped down to the designated voltage, while providing the necessary isolation from the line current. Then, the power will be passed through a rectifier circuit and transferred to the output connector.

Input AC voltage is isolated from the output DC voltage by the transformer. The transformer provides alternating current to the switching power supply, which is in charge of the rectification output regulation, allowing the voltage to reach a stable level.

The DT12PW190B boasts a wide-input voltage range of 100VAC to 240VAC, so that it can be used nearly universally. These plugs are designed for use in Great Britain, Europe, Asia, Australia, United States and other countries in the world.
