Introduction

AC/DC converters, often referred to as voltage converters, are an important part of power electronics and electrical engineering. Without using this technology, it would be almost impossible to distribute electricity effectively and safely. PFE850-12-054NA is a type of AC/DC converter commonly used in a wide variety of applications and suitable for use in harsh environmental conditions. The aim of this paper is to discuss the application field and working principle of PFE850-12-054NA in detail.

Application Field of PFE850-12-054NA

PFE850-12-054NA AC/DC converter is generally used in the industrial field, such as telecommunications, automotive, medical, and other demanding applications due to its high performance and high reliability. It is especially suitable for use in harsh environments due to its high degree of protection against shock, vibration, and dust.The PFE850-12-054NA AC/DC converter is suitable for operations where a wide input voltage range is needed and where low current but high voltage is required. It is capable of outputting DC voltages from 8V to 12V, making it ideal for use in a wide variety of applications such as medical equipment, LED lighting, aerospace, defense, and power conversion.

Working Principle of PFE850-12-054NA

The PFE850-12-054NA AC/DC converter is a switch mode power supply (SMPS) which works by using a switch and a storage element such as an inductor or a capacitor to store energy when the switch is off. When the switch is on, the energy stored in the inductor or capacitor is quickly released and the voltage is then stepped down via the switch to the desired level.This AC/DC converter also utilizes a rectifier circuit to convert the AC voltage to a DC voltage. The rectifier circuit is composed of four diodes (three positive and one negative) which allow the current to flow in one direction only. This rectified voltage is then passed through a filter capacitor which smoothes the output voltage and reduces the ripple voltage.The PFE850-12-054NA converter has a wide input voltage range (90-264VAC) and an output voltage range of 8V to 12V. It is also capable of outputting high current up to 54A. This AC/DC converter is highly efficient and is able to achieve a full load efficiency of up to 94%. It is also capable of operating over a wide temperature range (-40°C to +85°C).

Conclusion

In conclusion, the PFE850-12-054NA AC/DC converter is highly suitable for use in a wide variety of applications due to its wide input voltage and output voltage range, high current capability, and high efficiency. Moreover, it is very reliable even in harsh environmental conditions and is capable of operation over a wide temperature range. The working principle of the PFE850-12-054NA AC/DC converter includes the use of a SMPS which is composed of switches and power storage elements and a rectifier circuit.
