The Artesyn Embedded Power LPS40 series, including the LPS45 model, offers open-frame AC/DC conversion solutions. This series provides a total power output of 25 to 40W, with specific models delivering voltages of 5V, 12V, 15V, or 24V. The LPS45 features a universal input range of 85 to 264 VAC or 120 to 300 VDC, making it versatile for various applications.
Key electrical specifications include a typical efficiency of 70% at full load, an input current of 1A max (RMS) at 115 VAC, and a switching frequency of 110 KHz. The unit offers 40W of output power with free air convection cooling and can deliver up to 55W with 30 CFM of forced air. It includes essential protections such as output overvoltage and short-circuit protection, along with remote sense capability.
Mechanically, the LPS45 has a compact 3" x 5" footprint and is less than 1U high, suitable for space-constrained designs. It is designed for applications in medical, test and measurement, single-board computers, telecommunications, and networking. The unit is chassis mountable and features a universal input.
Environmental specifications include an operating temperature range of 0°C to 50°C ambient, with derating up to 70°C. It also meets various safety approvals including CUL, CSA, NEMKO, and CE marking.
The LPS45 accepts an AC input of 85 to 264 VAC or a DC input of 120 to 300 VDC.
The LPS45 provides a single output of 24V at 1.6A, delivering 40W with convection cooling or 55W with 30 CFM forced air.
The LPS45 operates from 0°C to 50°C ambient, with derating of 2.5% per degree from 50°C to 70°C, and can start up at -20°C.
The LPS45 measures 127.0 mm in length, 76.2 mm in width, and 29.0 mm in height.
The LPS45 includes short circuit protection on all outputs, overload protection at 110% to 145% of peak rating, and overvoltage protection.
