Description

 

 

 

 

 

 

 

 

 

 

Branch circuit requirement

Each chassis power supply should have its own dedicated, fused-branch

 

 

 

 

 

 

circuit:

 

 

 

 

 

 

For North America—10 A

 

 

 

 

 

 

For International—Circuits sized to local and national codes

 

 

 

 

 

 

All AC power supply inputs are fully isolated.

 

 

 

 

 

 

Source AC can be out of phase between multiple power supplies

 

 

 

 

 

 

in the same chassis, which means that PS1 can be operating

 

 

 

 

 

 

from phase A and PS2 can be operating from phase B.

 

 

 

 

 

 

For high-line operation, the power supply operates with the hot

 

 

 

 

 

 

conductor wired to a source AC phase and the neutral conductor

 

 

 

 

 

 

wired either to ground or to another source AC phase as long as

 

 

 

 

 

 

the net input voltage is in the range of 170 to 264 VAC.

34.00 A @ +12 VDC

 

 

 

 

 

 

 

 

 

 

Output holdup time

Front panel LEDs

 

 

 

 

 

 

INPUT OK

 

Green—Source AC voltage is OK. (Input voltage is 82 VAC or

 

 

 

 

 

 

greater.)

 

 

 

 

 

 

Red—Source AC voltage is less than 73 VAC (±3 VAC)

 

 

 

 

 

 

Off—Source AC voltage falls below 70 VAC, is not present, or the

 

 

 

 

 

 

power supply is turned off.

 

 

 

 

 

 

Note In chassis equipped with dual power supplies, if one power

 

 

 

 

 

 

supply is powered on and the other power supply is powered off,

 

 

 

 

 

 

the INPUT OK LED is lit red rather than unlit on the power

 

 

 

 

 

 

supply that is powered off.

 

 

 

 

FAN OK

 

Green—Power supply fan is operating properly.

 

 

 

 

 

 

Red—Power supply fan failure is detected.

 

 

 

 

 

 

Off—Power supply is powered off.

 

 

 

 

 

 

Note In chassis equipped with dual power supplies, if one power

 

 

 

 

 

 

supply is powered on and the other power supply is powered off,

 

 

 

 

 

 

the FAN OK LED is lit red rather than unlit on the power supply

 

 

 

 

 

 

that is powered off.

 

 

 

 

OUTPUT OK

Green—The 12 VDC output is within margins.

 

 

 

 

 

 

Red—The 12 VDC output is out of tolerance (less than 11.15 VDC or

 

 

 

 

 

 

more than 13.10 VDC).

 

 

 

 

 

 

Off—The power supply is off.

 

 

 

 

 

 

Note In chassis equipped with dual power supplies, if one power

 

 

 

 

 

 

supply is powered on and the other power supply is powered off,

 

 

 

 

 

 

the OUTPUT OK LED is lit red rather than unlit on the power

 

 

 

 

 

 

supply that is powered off.
