300 W AC-DC power supply for server and computing systems

14 February 2001 Power Electronics / Power Management

Artesyn Technologies' CVN300, a multi-output, AC-DC power supply designed for communications systems, meets Intel's server systems infrastructure (SSI) requirements for an entry power supply (EPS). Incorporating an industry standard form factor with functional performance features, the CVN300 comes in a 8,6 x 15 x 14 cm package and uses an industry standard form factor, providing wide design flexibility. Unlike standard ATX supplies, the CVN300 has extensive peripheral and auxiliary connectors, allowing users to configure it for a variety of server, communications and computer system applications. The modules are internally cooled and contain a fan monitoring signal and a fan control signal, allowing external diagnostics and control of fan operation.

All modules offer five output voltages (+3,3, +5, +12, -12/5 V SB) that are compatible with current microprocessor platforms used in server systems and allow for migration to future microprocessor platforms. Remote sensing of the +3,3, +5 and +12 V outputs allows users to configure systems for tight voltage regulation.

The minimum efficiency of the CVN300 is 70% over the specified range of input voltage. The end user will benefit from a robust thermal design, improved system performance and high reliability. The CVN300 uses power factor correction and complies with EN61000-3-2. The universal AC input allows for 90-264 V a.c., 50/60 Hz and single-phase operation. The CVN300 also incorporates EMI filtering that meets conducted and radiated FCC and CISPR22 Class B limits.
