The Artesyn Embedded Power LPT81 is an open-frame, chassis-mount AC/DC converter designed for ITE (Commercial) applications. It provides three outputs: +3.3V, +5V, and +12V, with a maximum power of 60W under convection cooling, expandable to 85W with forced air.
Key electrical specifications include a universal input voltage range of 85-264 VAC or 120-300 VDC, and an efficiency of 75% typical at full load. The converter features power factor correction, built-in EMI filtering (FCC Class B, CISPR 22 Class B), overvoltage protection, and overload protection. It also includes remote sense and remote inhibit capabilities.
The physical dimensions are 5.00" L x 3.00" W x 1.29" H (127.0mm x 76.2mm x 32.8mm). The operating temperature range is 0°C to 70°C with derating. Safety approvals include CB and CE.
