550W open frame power supply for power over Ethernet ...

The TNP550-5412 power supply delivers 550W of continuous power with cooling conditions of 19 CFM for PoE applications. It has isolated 12V and 54.5V DC outputs along with 1.5K Vac isolation between protective earth and return in a frame measuring 190 x 89 x 35 mm (7.48in (L) x 3.54in (W) x 1.38in (H))

This makes the power supply well suited for PoE networking applications in high temperature environments, operating from -20°C and 70°C, while derating linearly from 100% load at 50°C to 50% load at 70°C.

The supply has a low inrush current of 60A maximum @ 230VAC, at 25°C cold start with built-in power factor correction (PFC) and protections for over voltage, over current, short circuit, and over temperature.

The units have an operating altitude of up to 5,000 meters and an MTBF of 500,000 hours minimum at full load, 25°C ambient, calculated per Telecordia SR-332.

The 550W power supply is approved to the latest IEC/UL 62368-1 (3rd Edition) ITE standards and complies with immunity standards, including EN 55032, FCC/VCCI class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-3-3, EN 61000-4-2, EN61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, and EN 61000-4-11.

The TNP550-5412 is competitively priced in OEM quantities.
