Server format

Seasonic SS-500L1U is a server power supply in EPS 1U format, which in thickness occupies only one rack in the mounting cabinet. On the main +12 V line it produces 480 W of power. It has a completely modular cable design, although the set of connectors differs from the desktop ATX standard. Reactive power correction method - Active PFC 99%.

Gold certificate

While the efficiency can reach 92% with a European input voltage of 230 V, which corresponds to the 80 PLUS Gold energy efficiency certificate. Operation is also supported in American 110-volt electrical networks. Stabilization of output low-voltage lines - progressive separate DC-DC. Implemented protection against overload, short circuit and power surges.

Double bearing

It is cooled by a fan with a small diameter of 40 millimeters, but with a high rotation speed (silence from the servers is not required). Double ball bearings minimize lubricant leakage, which ensures trouble-free operation of up to 100 thousand hours. Semi-passive cooling at low load on the power supply completely stops the fan.
