VE-B40-IU

DC DC converters are electronic power converters that can convert one DC voltage level to another, pushing DC power through the conversion process. One of the most popular models is the VE-B40-IU, which is used as an isolated and regulated DC power supply for the availability and reliability of the DC voltage. This article will discuss the application field and working principle of the VE-B40-IU DC DC converter.

The VE-B40-IU DC DC converter is a compact, isolated low-power DC to DC converter fabricated with high-density surface mount devices. It is mainly used for applications in telecommunication, industrial control, military systems, navigation systems, computers and metering systems. It has an input voltage of +36 to +60 VDC, and an output voltage of +5.2 to +40 VDC. It is designed with efficiency up to 95% and a wide operating temperature range from -40°C to +85°C.

The VE-B40-IU converter utilizes an isolated flyback topology, which is a technique used to direct energy transfer from a source to a load. This topology involves the basic building blocks of primary active circuit, power switch, inductor, diode, and output filter. To start the conversion process, the primary active circuit allows an electric current to flow through its winding and generates a magnetic field. This magnetic field is then transferred to the primary winding of the power switch, and then to its output stage. The diode then rectifies the alternating current (AC) voltage across the output stage, producing a DC output voltage. Once the source power is cut off, the inductor will collapse and the stored energy will be returned to the primary circuit, thus creating a flyback effect.

The VE-B40-IU is designed with over-voltage protection, over-temperature protection, short circuit protection, and overload protection. This device features a high efficiency, low ripple noise, and low external component count. It is shielded with a metalized plastic box which provides minimal EMI/RFI interference. It also has an adjustable output voltage and power good signal, and is certified with the UL 60601-1 medical safety standard.

The VE-B40-IU DC DC converter is an isolated, efficient, and low-cost DC to DC converter, ideal for mission-critical, regulated power supply applications. Its range of applications also includes automotive and industrial control, portable electronics, medical systems, and renewable energy sources. Its features make it a great choice for a wide variety of applications, and it has proven to be a reliable and cost-effective device.
