AC/DC converters are power electronic converters that bridge the gap between existing AC power networks and the various DC devices which make up a large portion of electrical equipment. The RACM65-05S AC/DC converter is a highly efficient and low power alternative to the traditional AC/DC power supply. It is well suited for use in critical applications, such as those found in the medical, military, and aerospace industries, and is especially useful for those that must operate in harsh conditions or require wide input voltage ranges.

The RACM65-05S utilizes a fractional-slot winding toroidal transformer design to achieve high efficiency and low power dissipation. This winding technique is beyond the scope of this document, but the basic idea is that the transformer is split into sections and the primary and secondary windings are distributed over each respective side. This allows for enhanced flux optimization by ensuring that the current paths always travel in the same direction, allowing for increased efficiency. Additionally, the toroidal form factor helps to reduce radiated electromagnetic interference caused by the high frequency operation.

The RACM65-05S derives its DC output from single-stage rectification by utilizing a higher frequency PWM controller and sensing circuit. This eliminates the need for large filter capacitors, which improves efficiency and decreases system size and cost. The device includes power and current regulation, allowing for high output accuracy, and includes status monitoring features to provide monitoring and control capabilities for increased system safety and reliability.

The input voltage range of the RACM65-05S is particularly wide – it supports both high- and low-voltage input from 85 to 265V AC, making the device widely applicable in different applications. Furthermore, it supports both active power factor correction (PFC) and standby power consumption lower than 0.5W, making it compatible for low standby power standards such as Energy Star. The fully-filtered output voltage is adjustable between 13.8 and 35V DC, allowing for wide flexibility in the type of loads it can power.

The RACM65-05S power converter’s combination of cost-effectiveness, high efficiency, and wide input and output voltage ranges make it ideal for a variety of applications. Primarily, it is used in industrial electronics, medical devices, communications equipment, charging systems, and LED lighting and displays. Additionally, its universal input capability makes it well suited for high-end applications such as military or aerospace equipment, and its compact size fits the industry trend of miniaturization.

In conclusion, the RACM65-05S AC/DC converter offers a versatile and reliable power solution that balances performance with cost. Its widened input AC voltage range and cost-effective design make it ideal for a variety of applications, from medical electronics to military equipment. Its robust design and comprehensive monitoring capabilities make it a safe and reliable alternative to traditional AC/DC power supplies.
