Application Fields

The RV-2412D/R6.4 is primarily designed to meet the needs of power supply systems in transportation, aerospace, industrial, and telecommunications fields. It can be used in a variety of systems, such as grid networks, renewable power systems, and distributed generation systems, for purposes such as charging industrial and traction batteries, regulating system voltages, and providing surge power.

Working Principle of RV-2412D/R6.4

The working principle of the RV-2412D/R6.4 can be understood in two steps. First, the device rectifies, converts, and controls the input voltage into a stabilized DC voltage. This is done through an internal Rectifier-Filter-Regulator (RFR) module. This module uses a rectifier bridge at its input and capacitors (or inductors) at the output, to smooth out the current and convert the AC input to a stabilized DC voltage. The regulator part of the RFR module then controls the output of this voltage to ensure consistent performance and maintain the desired level of operation.

The second step of the working principle involves the power switch that determines most of the device’s electrical characteristics. This is typically an integrated circuit switch - usually a metal-oxide-semiconductor field-effect transistor (MOSFET). The MOSFET is controlled by the RFR module to regulate the output of the converter and adjust its voltage to the desired level. It is also used to control the device’s maximum output current. Depending on the application, the RV-2412D/R6.4 can use up to two MOSFETs in parallel to increase its output current capability.

The RV-2412D/R6.4 comes in an IP67-certified enclosure and is suitable for use in harsh environments. It also includes several safety features to protect against transients, output overvoltage, surge voltages, reverse polarity, and over-currents. This makes it ideal for military and space applications as well as a variety of energy storage and power conditioning applications.
