These devices are most commonly used to provide a reliable DC power source for small to medium-sized electronics such as computers, televisions, lighting systems, cell phones, and various consumer and industrial products. The SWM30-12-EV-P6R AC DC Desktop, Wall Adapters offer adjustable output voltage from 10 to 24 VDC, with a peak output current of up to 6 Amps. In addition to the versatility in output voltage, the SWM30-12-EV-P6R AC DC Desktop, Wall Adapters feature built-in short-circuit and over-current protection, making it an ideal solution for powering and protecting a large variety of electronic devices. The device also features a reinforced insulated shell which helps protect it from fire hazards, and the included DC power cord is UL certified for additional safety and reliability.

Working Principle

The SWM30-12-EV-P6R AC DC Desktop, Wall Adapters use a diode bridge rectifier and transformer circuit to convert AC voltage from the wall outlet to DC voltage for powering the device. The diode bridge rectifier is made up of four semi-conductor diodes that convert the AC voltage to pulsating DC. The transformer is then used to reduce the voltage or increase the current. The transformer is connected to the diode bridge rectifier and serves the purpose of regulating the amount of electrical current and voltage passing through the device. The output of the transformer is then passed on to the regulator circuit, which is responsible for providing a constant DC voltage for powering the device. The SWM30-12-EV-P6R AC DC Desktop, Wall Adapters also include a short-circuit and over-current protection circuit to protect the device from improperly connected loads, over-currents, and other electrical faults. The short-circuit protection circuit is formed by a pair of FETs connected in series with the line voltage, which will quickly disconnect the load if the voltage across it exceeds a predetermined threshold. The over-current protection circuit is formed by a current sensing resistor connected in series with the output of the regulator, which will disconnect the load if the current draw exceeds a predetermined level. The SWM30-12-EV-P6R AC DC Desktop, Wall Adapters are an ideal source of DC power for a wide variety of applications, offering adjustable output voltage, safety features, and a reinforced insulated shell. The device also includes a UL certified DC power cord for increased safety and convenience. With these features, the SWM30-12-EV-P6R AC DC Desktop, Wall Adapters is the perfect choice for powering a variety of small to medium-sized electronics.
