AC/DC converters refer to DC power supply devices which can be transformed from AC power into a specific form of DC power. The DG120M-9 is a great example of this, utilized in a variety of applications due to its versatility. This article will determine the applications and working principles of the DG120M-9.

The DG120M-9 is primarily used in the fields of robot systems, industrial automation, factory automation, transistors, motor control, and communication systems. It is also popular in commercial uses such as advertising signage, instruments, security systems, inverters, and alternating current relays. Due to its availability in 18 different versions, as well as the unique Field-effect Transistor (FET) structure, the DG120M-9 allows users to save both energy and cost associated with the AC/DC conversion process.

The DG120M-9 operates using a classic PWM switching control which reduces inrush current on resulting fields. The device’s maximum power supply voltage (apply voltage) ranges from 18V to 75V, with a limiting current of 120mA. The output of this device is rated at 12V, an adjustable voltage ranging from -5V to + 5V. The power output of the DG120M-9 ranges from 15 to 120W, with the total power efficiency reaching up to 91%.

The structure of the DG120M-9 operates by first providing an AC input to a diode bridge rectifier. This rectifier contains four diodes connected in a bridge shape. By combining and alternating AC in and out of this bridge, the alternating current becomes direct current since both the positive and negative components of the AC cycle are directed out through the same side of the bridge. This output goes into an inductor to reduce the current input into the device. The following current is also smoothed out with a filter capacitor that is used for the input capacitor stage. Ultimately, the output of the smoothed and filtered direct current is directed on to a PWM switching control, which is designed to reduce the inrush current and control the output voltage. This is the primary step of the DC-DC conversion process, which works with the FET structure to provide an efficient output voltage.

The structure of the DG120M-9 also enables it to be used in medical device application, due to its fast response time. Upon demand, the device is able to provide a fast switching frequency to input different components of the device. This is significant for medical users because it eliminates any potential ups and downs affecting the medical device’s output, as well as any reverse current flow resulting from an unbalanced output load.

The DG120M-9 also offers protection functionality against overload, short circuit, and over temperature which prevents the device from burning out. This is especially crucial in industrial applications where the device may be used for long periods of time and is subject to higher levels of heat, as users don’t have to worry about constantly having to replace the device. Additionally, the DG120M-9 is CE certified, meaning it has met the requirements of the European Union’s Harmonized Standard as it relates to electromagnetic compatibility.

In conclusion, the DG120M-9 is a high performance AC/DC converter that provides excellent results in applications ranging from robotics to industrial automation. It utilizes a classic PWM switching control coupled with a FET structure, which results in high efficiency and low current on resulting fields during the DC-DC conversion process. It also features protection functions against over current, short circuit, and other conditions. The DG120M-9, due to its versatility and certification, is a great choice for individuals looking for an AC/DC power solution.
