DC-DC converters are widely used to manage and regulate the flow of direct current power in countless applications, from automotive and telecoms systems to industrial machinery and solar power systems. The Varirator Model VI-22M-EX-S is one such converter, designed to work in challenging environmental conditions while providing reliable, efficient and accurate power transfer between a renewable energy source and a load.

The VI-22M-EX-S is an isolated, low-profile, wide-range adjustable power supply that offers superior performance even under the most rigorous conditions. It operates at an input voltage range of 9 to 18 volts, providing a regulated output voltage range of 0 to 16 volts with a maximum output current of 10 amperes. The VI-22M-EX-S also features a built-in temperature overload protection circuit that automatically shuts down the device if the ambient temperature exceeds 130°C.

This DC-DC converter is highly efficient, consuming less than 0.2 watts in standby mode and less than 25 watts in normal operation. The VI-22M-EX-S offers excellent line and load regulation, providing a steady output with a maximum ripple of less than 15 mV peak-to-peak. The bright red LED indicator informs the user if the output voltage is too low or too high, meaning there is no need for manual adjustments. The VI-22M-EX-S also features reverse voltage protection and short-circuit protection for added reliability and peace of mind.

The VI-22M-EX-S can be used in a variety of applications. For example, it can be used to power mobile and stationary remote control vehicles, such as roof-mounted antenna systems or remote nodes. It can also be used to power industrial or medical equipment, such as lifts, trolleys, X-ray machines, CT and MRI scanners, autoclaves and monitoring devices. Similarly, the VI-22M-EX-S can power fuel cells and photovoltaic systems for renewable energy applications.

The VI-22M-EX-S also offers a wide range of operating temperature, from -20 to + 50 degrees Celsius. This enables it to operate reliably under extreme temperatures, ensuring reliable performance even in the most extreme environments. Moreover, the VI-22M-EX-S is designed to be immune to shocks and vibrations, making it ideal for use in demanding applications.

The VI-22M-EX-S is based on a new switching topology known as synchronous buck converter, which is designed to provide accurate, efficient and reliable power conversion. This topology allows the converter to achieve a high conversion efficiency of up to 94%, even at light load current. The input voltage, output voltage and load current are regulated by the combination of main switch, PWM controller, error amplifier, current sense amplifier and voltage reference, which makes the VI-22M-EX-S very easy to control.

Overall, the Varirator Model VI-22M-EX-S is an excellent choice for a wide range of DC-DC conversion applications. It offers superior performance, reliable operation and reliable protection features even in the harshest environmental conditions. The top-level efficiency, wide input voltage range and adjustable output voltage make the VI-22M-EX-S an ideal choice for any application requiring reliable power conversion.
