DC DC Converters

VE-26V-MW-S is a DC DC converter. It is used to provide a regulated voltage output from an unregulated voltage input for a variety of applications. This converter is useful for applications such as automotive, aerospace, instrumentation, and medical equipment.

Application Field

The VE-26V-MW-S DC DC converter operates over a wide range of temperatures, from -40°C to +125°C. It has a wide input voltage range, from 4.75 VDC to 28 VDC. The output voltage is factory preset to a value within the 2.5V-26.5V range which can be easily set, changed or adjusted from the front panel with no tools. The power rating is 20W.

It features an advanced true isolation design, allowing the power device to be completely isolated from the input source and the output load. Additionally, the output voltage is adjustable, allowing users to customize the output voltage to their specific needs.

The VE-26V-MW-S is designed to provide a regulated DC output voltage while tolerating a wide range of input voltage, load variations. All models have a pin compatible pinout making them suitable for a variety of applications.

The VE-26V-MW-S is designed to protect against input voltage and current overshoot, short circuit, ground faults, and thermal shutdown. It has an industry leading efficiency which keeps power losses to a minimum and maximizes system reliability.

Working Principle

The VE-26V-MW-S DC DC converter works by taking an unregulated input voltage from the source, such as a battery, and converting it to a regulated output voltage. This is accomplished by using a DC-DC (or DC/DC) switching regulator. The regulator is essentially a switch that is turned on and off at very high speeds, usually in the range of 500kHz to 1MHz. When the switch is on, it allows current to flow through an inductor, from the input source, to the output, and when the switch is off, the inductor stores the energy. This stored energy is used to maintain the output voltage, even when the input voltage is fluctuating.

The output of the regulator is set using an adjustable voltage regulator, typically incorporating a voltage reference, an error amplifier, oscillator, and control logic. The reference voltage used for the output voltage setting is factory preset. However, it can be easily adjusted from the front panel.

The VE-26V-MW-S DC DC converter is designed to deliver superior performance and reliability in a wide range of temperature environments. It provides overload, overvoltage, and undervoltage protection, as well as a temperature protection circuit. It is also designed to resist shock, vibrations, and other environmental stress that could affect the performance of the converter.
