ME20A0902B01

AC DC Desktop, Wall Adapters

The ME20A0902B01 ac dc desktop wall adapter is an excellent choice for any home-automation or telecommunication application that requires reliable, safe and secure ac/dc communications. This product is UL certified and is supported by a two-year limited warranty.

The ME20A0902B01 is a single-phase ac/dc wall adapter with a rated input voltage of 120/240 volts ac (50/60 Hz) and an output voltage range of either 5 or 12 volts dc. The power cord has a standard NEMA 5-15 plug and the case is a rigid die-cast aluminum that is designed for maximum durability and heat dissipation. The unit is designed to operate in both continuous and (inrush) current limiting modes and it has four adjustable output settings that allow you to customize the voltage and current output for your specific applications. The unit also includes a power switch and built-in surge protection.

Application Field

The ME20A0902B01 ac/dc wall adapter provides a great solution for any home-automation or telecommunication application. With its adjustable outputs and power switch, this unit is perfect for powering computers, sensors, speakers, LEDs, and any other device that requires ac/dc power. Its size and durability make it great for permanent mounting, commercial and heavy-duty applications. The unit is also UL certified, so it is guaranteed to meet safety standards.

Working Principle

The ME20A0902B01 operates on the basis of a simple circuit. The unit is a full-bridge rectifier converter which takes in an ac voltage from an input source (such as a wall socket) and converts it into a regulated dc voltage. The rectifier bridge is composed of four diodes which conduct current alternately depending on the input voltage polarity. This circuit is regulated by either a current-limiting device (such as a transformer) or a voltage-limited device (such as a series resistor). The output voltage of the unit is adjustable and is dependent on the input voltage from the plug. The unit also features a power switch which automatically turns off the output when the input voltage is too high or too low.

The ME20A0902B01 ac/dc desktop wall adapter is a reliable, safe, and secure choice for any application. With its adjustable output and surge protection, it is an ideal solution for any home-automation or telecommunication application.
