The EPL225PS48 is an AC/DC converter that provides power supply for telecommunications equipment. It is rated for input voltage between 90V and 264V, output voltage that can reach 48V and a maximum output current of 225A. The system features high efficiency, low ripple, and low profile with a height of just 1U.

The EPL225PS48 is made up of two main components, an AC/DC converter and a DC/DC converter. The AC/DC converter, also known as a rectifier, takes the AC input voltage from the mains and converts it into a DC voltage. This rectified DC voltage is then fed to the DC/DC converter which is responsible for the final conversion of the voltage to the required levels. For the EPL225PS48 this can range from 18 to 48V.

The design of the EPL225PS48 is based on a resonant zero-voltage switching (ZVS) principle and resonant current-mode switching. This ensures that no electrical noise is generated during switching, making it suitable for noise-sensitive applications. It is also designed to work efficiently at any level of output power, a feature that Mains-In power supplies do not feature.

The EPL225PS48 is primarily used in the telecommunications and data centers. It is suitable for powering switching systems, optical transmission systems, and repeaters used in optical communication systems. Due to its high efficiency, low noise, and low profile design, it is an ideal choice for powering high-density server racks. It is also the perfect choice for powering power-hungry telecommunications systems, as it boasts up to 94.5% efficiency. Additionally, its 6-stage active power factor correction ensures that power is utilized efficiently and is compliant with international standards including 231 Harmonics limits.

In terms of safety, the EPL225PS48 features over-voltage, over-current, and over-temperature protections to ensure the stability of the system. It also supports an inrush current limiting feature, which reduces inrush current when the system is powered on. With a wide temperature range of -40°F to +185°F, it can handle extreme temperatures and adverse environmental conditions.

Overall, the EPL225PS48 is an advanced AC/DC converter that is ideal for telecommunications and data center applications. Its highly efficient design, low noise, and low profile make it a great choice for powering high-density server racks. Additionally, its various safety features ensure that power is used efficiently and that the system runs safely and reliably.
