Server power rack has hot-swap reliability

New from Minebea, the SD241U server power rack features the Phoenix series of power supplies specified for server use in an n+1 configuration, enabling system redundancy and continuity of service.

New from Minebea, the SD241U server power rack features the Phoenix series of power supplies specified for server use in an n+1 configuration, enabling system redundancy and continuity of service.

A maximum of four power supplies are capable of parallel operation and offer 4 x 400W or a maximum output power of 1200W.

All ORing devices are integral with the power supply, and so only the minimum of logic functions need to be implemented on the system backplane.

Appropriate current sharing is employed to parallel the main output voltages.

Hot swap technology is implemented such that the AC power cord is removed for unit insertion or removal.

The Phoenix is optimised to allow quiet system operation using advanced fan control compliant with the standard PC98 interface.

E2PROM unit identification is also included for automated system inventory.

The modules offer a wide range input of 90-264V AC with wide-ranging active PFC, and are tested for ambient temperatures up to 50C.
