The Artesyn Embedded Technologies LPQ253-CEF is a 250W embedded switch-mode power supply designed for AC to DC conversion. This enclosed unit features a quad output configuration, providing 5V dc and ±15V dc with specific current ratings of 6A, 10A, and 35A. It operates with a universal input voltage range of 85-264V ac or 120-300V dc and boasts an efficiency of 75% at full load.
Key features include active power factor correction, a built-in EMI filter, and overload/thermal overload protection. The power supply is designed for chassis mounting and comes supplied with a dual end-mounted fan. It is suitable for ITE (Commercial) applications and meets various safety and EMC certifications including CB, CE, CSA, and UL.
Dimensions are 262mm in length, 127mm in width, and 76.2mm in depth. The operating temperature range is from 0°C to 70°C with derating. This model is not convection rated and requires forced air cooling if optional fans are not used.
