VI-204-MX-F4

DC DC Converters

DC-DC converters are electronic devices which can convert a DC voltage of one polarity into a DC voltage of opposite polarity. Their function is to control the voltage, current, power, and impedance of power sources and electrical systems. DC-DC converters are available in two basic types: linear and switch-mode.

VI-204-MX-F4 Application Field and Working Principle

The VI-204-MX-F4 is an automated continuous duty DC-DC converter designed for switching regulated automobile batteries and other automotive applications in the 18V to 36V dc range. It is suitable for use in truck fleets, off-grid applications, and industrial applications where continuous monitoring and control of input and output is required. The working principle is that a high-frequency, high-efficiency MOSFET transistor is used as the switching component. The switching frequency is adjustable from 20 KHz to 250 KHz, and the output voltage can be set between 0.8V and 38V. The control parameters are set with the help of an external software, with parameters being displayed on an LCD panel.

The VI-204-MX-F4 implements a pulse-width modulation (PWM) type of switching to regulate the output voltage. The PWM current is generated to regulate the output voltage and is compared with the feedback voltage. A series of pulses is generated which allows for a smooth transition between high and low output voltages, with minimal ripple. The switching frequency is controlled by the pulse frequency and the duty cycle of the pulses. The duty cycle of the pulses is dependent on the input voltage, output voltage, and the current of the application.

The VI-204-MX-F4 is equipped with short-circuit protection, over-voltage protection, and an overload protection. It is also protected from excessive temperature increases, preventing it from potentially damaging electrical components in the vicinity. It has an operating temperature range of -35ºC to +70ºC.

It is a high-frequency, high-efficiency converter that can be used for a variety of applications such as DC-DC battery charging, industrial applications, and vehicle electrification. It can be used to provide regulated DC voltages to electric vehicles, or to control load sharing between multiple power sources. It can also be used in solar applications, where it can provide a regulated voltage source to charge a battery or control the power flow between a solar panel and a battery in an off-grid system.

The VI-204-MX-F4 is a very versatile DC-DC converter that has many advantages over traditional linear converters. It is capable of handling large loads, has high efficiency, and has limited EMI emissions. Furthermore, it has numerous protection features and is easy to configure and maintain.
