OCPRF100 MP Server System Technical Product Specification

Revision 1.0

tions. Protection circuits in the power supply will not cause the AC fuse to blow unless a component in the power supply has failed. This includes DC output load short conditions. The DC load short circuit protection circuits will shut down or limit power supply without causing the AC line fuse to blow.

5.5.3.3Power Factor Correction

The power supply incorporates a power factor correction circuit.

The power supply is tested as described in EN 61000-3-2: Electromagnetic Compatibility (EMC)

Part 3: Limits- Section 2: Limits for Harmonic Current Emissions, and must meet the harmonic current emissions limits specified for ITE equipment.

The power supply is tested as described in JEIDA MITI Guideline for Suppression of High Harmonics in Appliances and General-Use Equipment and must meet the harmonic current emissions limits specified for ITE equipment.

5.5.4DC Output Specification

The power supply DC output specification is met by a single supply, by two supplies, or by three supplies operating with their outputs directly paralleled. When operated in parallel, the supplies share the total load currents equally within the limits specified, and meet all performance requirements of individual supplies. Failure of a supply in a paralleled group, or removal of an operational or failed supply from a paralleled group will not cause DC output transients in excess of the limits specified. Adding an operational or failed supply to a paralleled group will not cause DC output transients in excess of the limits specified.
