1570W Power Supply

10. 1570W Power Supply

This section describes some of the power supply features. It is a current sharing power supply
with auto ranging input. The dimensions of the power supply are 7.75-inches (W) x 14.5-inches
(D) x 1.47-inches (H).
The output rating of the power supply is 1570W when operated between 200VAC and 240VAC.
The system can run with only one power supply installed. For redundancy, two power supplies
must be installed.

10.1 AC Input Requirement

10.1.1

AC Input Voltage Specification

The power supply will operate over the range and limits shown in Table 21.

Vin (turn-off)
The main outputs of the power supply will turn off per VIN (turn-off). Any standby outputs may
continue to operate at input AC voltages below VIN (turn-off).
10.1.2

Efficiency

The power supply will have a minimum efficiency of 80% when operated under the maximum
loading conditions at 90VAC-240VAC.
10.1.3

Input Over-Current Protection

The power supply has internal primary over-current protection. A normal-blow (fast blow), high-
breaking-capacity fuse is placed in the input circuit.
10.1.4

Inrush Current

When input power is applied to the power supply, any initial current surge or spike of 10ms or
less will not exceed 55A peak. Any additional inrush current surges or spikes in the form of AC
cycles or multiple AC cycles greater than 10ms, and less than 150ms, will not exceed 25A peak.
