VOF-70-48 Power Supplies - External/Internal (Off-Board)

AC/DC converters are electrical systems that affect an AC voltage to an DC voltage or vice versa. This is usually done using a transformer to step up or step down the voltage, depending on the application. In most cases, however, the transformer is only used to temporarily store the energy that needs to be converted. The actual conversion is done with the use of power electronic components such as diodes, MOSFETs, and thyristors. The VOF-70-48 is such an AC/DC converter, which offers a variety of features that makes it suitable for many different applications.

VOF-70-48 Application Field

The VOF-70-48 has a wide range of applications, from industrial to solar and automotive. It can be used to regulate the input voltage of photovoltaic systems, convert the output of AC alternators into DC, or for any other application that requires an AC/DC converter with high efficiency and reliability. The maximum output current of this device is 48 Amps, making it suitable for applications that require higher power. It also features a wide input voltage range, from 40V to 690V, and a wide output voltage range, from 40V to 800V, which makes it suitable for a variety of applications.

VOF-70-48 Working Principle

The VOF-70-48 consists of several power electronic components, including two MOSFETs, two capacitors, and two diodes. The MOSFETs act as switches that turn on and off in order to regulate the input voltage and output voltage. When the input voltage is higher than the output voltage, the MOSFETs turn on and allow the current to flow through the load. When the input voltage is lower than the output voltage, the MOSFETs turn off and the capacitors are charged storing the energy which is then used to supply the output voltage. The diodes are used to protect the circuit against reverse current and short circuit.

The VOF-70-48 also features a number of protection mechanisms, such as over-voltage, over-current, and over-temperature protection. These protections ensure that the device cannot be damaged due to abnormal conditions. In addition, the device also has a parallel connection feature, which allows multiple devices to work in parallel and increase the output current.

The VOF-70-48 is a versatile and reliable AC/DC converter that can be used in a wide range of applications. It features high efficiency and a wide input and output voltage range, making it suitable for applications that require higher power. With its various protection mechanisms and parallel connection feature, the VOF-70-48 is an ideal solution for a variety of applications.
