1 Purpose
This specification defines the performance characteristics of a single-phase (3-wire), 1620W single output power supply with wide range input AC capability (90-264VAC/47-63Hz). The power supply shall be designed for parallel operation. In the event of a power supply failure, the redundant power supply continues to power the system even under over voltage fault. The power supply shall be designed for “hot swap†exchange and shall communicate to external devices through Inter-Integrated (I2C) Circuit protocol. The power supply will have an EEPROM for storing powers supply FRU information, and meet PMBus Revision 1.2 requirement.
2 AC Input Requirements
The power supply shall incorporate universal power input with active power factor correction, which shall reduce line harmonics in accordance with the EN61000-3-2.
2.1 AC Inlet Connector
The AC input connector shall be an IEC 320 C-14 power inlet. This inlet is rated for 15A / 250
VAC.
2.2 AC Input Voltage Specification
The power supply must operate within all specified limits over the following input voltage range. Harmonic distortion of up to 10% THD must not cause the power supply to go out of the specified limits. The power supply shall operate properly at 85 VAC input voltage to guarantee proper design margins.

2.3 Input Under Voltage
The power supply shall contain protection circuitry such that application of an input voltage below the minimum specified in section
2.2
shall not cause damage to the power supply.
2.4 Efficiency
This power supply shall meet 80PLUS Platinum efficiency requirement, the efficiency and power factor should meet or exceed the below requirement.

2.5 AC Line Fuse
The power supply shall incorporate one input fuse on the LINE side for input over current protection to prevent damage to the power supply and meet product safety requirements. Fuses should be slow blow type or equivalent to prevent nuisance trips. AC inrush current shall not cause the AC line fuse to blow under any conditions. All protection circuits in the power supply shall not cause the AC fuse to blow unless a component in the power supply has failed. This includes DC output load short conditions.
2.6 AC Inrush
The power supply must meet inrush requirements 2.2 for any rated AC voltage, during turn on at any phase of AC voltage, during a single cycle AC dropout condition, during repetitive ON/OFF cycling of AC, and when input power is applied to the power supply any initial current surge or spike of 10ms or less will not exceed 25A peak.
2.7 AC Line Transient Specification
AC line transient conditions shall be defined as “sag†and “surge†conditions. Sag conditions (also referred to as “brownout†conditions) will be defined as the AC line voltage dropping below nominal voltage. The power supply shall meet the requirements under the following AC line sag and surge conditions.

2.8 AC Line Fast Transient Specification
The power supply shall meet the EN61000-4-5 directive and any additional requirements in IEC1000-45:1995 and the Level 3 requirements for surge-withstand capability, with the following conditions and exceptions:
•
These input transients must not cause any out-of-regulation conditions, such as overshoot and undershoot, nor must it cause any nuisance trips of any of the power supply protection circuits.
•
The surge-withstand test must not produce damage to the power supply.
•
The supply must meet surge-withstand test conditions under maximum and minimum output load conditions.
