The VI-27P-CX is a special type of DC to DC converter that was specifically designed for aircraft applications. The main features of this device include a wide voltage input range, high efficiency, long life expectancy, and a high pulse current capability. This article will discuss the application field and working principle of the VI-27P-CX.The VI-27P-CX is a high-performance DC to DC converter that is designed to provide an efficient and reliable source of power to aircraft and other vital systems. The device is well suited for a wide range of applications, such as power conditioning of RF amplifiers, providing main power to systems, and driving amplifiers/ sensors/actuators. This device is capable of operating from a wide input voltage range of 20-60V. The maximum current capability of the device is 28A and the peak current capability is 44A. In addition, the device features a high efficiency of up to 90%, making it exceptionally energy efficient.The working principle of the VI-27P-CX is based on the concept of switching regulation. In this design, the input voltage is switched on and off in a controlled way so as to maintain the output voltage at a constant level. The switching frequency is high enough so that the output voltage does not fluctuate significantly. The switching frequency is adjustable, giving the user control over the output.The VI-27P-CX uses a synchronous rectification design which reduces power losses significantly. This design utilizes a high-frequency clock to control two transistor switches in a loop. When an input voltage is applied, the clock triggers the switches. As the switches open and close, electrical current is updated more efficiently in the output circuit, keeping the output voltage level stable.The VI-27P-CX has a wide operating temperature range from -40°C to +105°C. The device is designed to be robust and reliable, capable of withstanding extreme temperatures and harsh environments. The device is designed with a high immunity to electromagnetic interference, ensuring its reliable operation in noisy environments.The VI-27P-CX is a highly efficient and reliable DC to DC converter that is ideally suited for aircraft applications. The wide range of features and benefits make it an ideal solution for providing power to a variety of devices and systems. The device has a high efficiency level, long life expectancy, and a high peak current capability which make it an excellent choice for power applications.
