RACM65-48S-ST

AC/ DC converters are used in many applications. These electrical components convert alternating current (AC) to direct current (DC) in order to power a device that requires DC voltage. One such example is the RACM65-48S-ST, a device that provides efficient and reliable power conversion. In this article, we will discuss the RACM65-48S-ST’s application field and working principle.

The RACM65-48S-ST is designed to be used in constant-current-mode applications with non-zero output voltage and input voltage rating from 90V AC to 140V AC. Typical uses include LED lighting, industrial automation equipment, power supplies, motor drives, solar energy systems, and vibration motors. With a wide input voltage spectrum and built-in over-voltage, over-current, and over-temperature protection, the RACM65-48S-ST ensures long-term reliability for a variety of applications.

The RACM65-48S-ST uses a pulse width modulation (PWM) controlling method for power conversion. It features active power factor correction (PFC) with a PF> 0.98 and a power factor input current THD < 10%. The RACM65-48S-ST offers a constant voltage output of 48V DC, a maximum current rating of 65A, and a minimum input current of 44V AC. With its built-in primary and secondary protections, the RACM65-48S-ST ensures stable and reliable operation.

The RACM65-48S-ST also comes with an efficient cooling system to dissipate heat and keep the converter at a safe operating temperature. The integrated cooling fan can be configured to operate between 40% and 100% speed, depending on the power load. The fan can also be manually set to work at fixed speed or set to auto-mode, where it will adjust its speed based on the detected power load.

In addition to power conversion, the RACM65-48S-ST includes an integrated protection module to protect against over-voltage, over-current, and over-temperature conditions. The module also provides a three-level protection, allowing for safe use in high-voltage and high-power systems.

Finally, the RACM65-48S-ST includes an integrated controller for monitoring power levels, output voltage, and temperature. This allows users to adjust the performance of the converter according to the application requirements, thus ensuring an optimal performance.

In summary, the RACM65-48S-ST is an efficient and reliable power converter designed for use in constant current mode applications. Its wide input voltage range, built-in protection module, and adjustable cooling fan make it suitable for use in a variety of settings. With its integrated monitoring system, the RACM65-48S-ST can be adjusted to provide optimal performance in any application.
