AC DC Desktop, Wall Adapters – L6R120D-480-C6 application field and working principle

The L6R120D-480-C6 series of AC/DC desktop, wall adapters are a highly efficient power supply. It utilizes an efficient switch-mode power conversion system, eliminating the need for bulky, inefficient linear power supplies. This series of adapter is widely used in applications such as consumer electronics, communication systems, industrial automation, medical equipment, and lighting. As a high-temperature, heavy-duty adapter, it offers the best in efficiency, sizing and cooling.The L6R120D-480-C6 series contain dual outputs, with an output voltage range from 9V to 35V DC, and an available load capacity ranging from 0.3A to 12A. This series is available in an AC input range from 85V to 264V, with power levels up to 120W. The design of this series is such that it provides a high input voltage range, high efficiency market, low ripple and noise.

Working Principle

The L6R120D-480-C6 series of AC/DC desktop, wall adapters use a PFC (Power Factor Correction) circuit. This helps reduce the current waveform distortion that occurs when a standard converter is used with a varying load. This allows for improved power factor performance, resulting in improved efficiency and higher power levels.The PFC also helps reduce the amount of EMI (electromagnetic interference) or RFI (radio frequency interference) generated by the converter. This ensures that the AC/DC adapter operates quietly without generating too much interference with other electronic devices.The advanced technology used by the L6R120D-480-C6 series also ensures high reliability and long-term survival. The design uses high-temperature components and features a high-temperature auto-recovery fuses. It is equipped with a OVP (Over Voltage Protection) and OCP (Over Current Protection) which help protect the converter from damage due to sudden changes in load. The OTP (Over Temperature Protection) also helps protect the converter from damage due to excessive heat.
