DESCRIPTION OF FEATURES & OPTIONS (cont’d)
FEATURE / OPTION
DESCRIPTION
No Load Operation
The module output can be operated down to zero load while
maintaining output regulation.
Hot Swap Operation
Hot swap operation means that the converter modules can be
removed and replaced while the rack/shelf is powering the load.
If the system is operated in an N+1 redundant mode, hot-swap
replacement will not affect the output voltage.
Output Protection
Output current limiting protects the output of each converter
module
from damage due to an overload or short circuit condition. This
protection is continuous, without damage, and recovery is auto-
matic when the overload is removed. Current limiting begins at
about 105% of rated output current.
LED Indicators
The Input Power Good indicator is a green LED, showing that
input DC is present. The Output Power Good indicator is a green
LED showing that the output voltage is present and within oper-
ating range.
Control and Monitoring
Signals
For detailed description of Inhibit, Current Share, Remote Sense,
Remote Adjust, Input Power Good and Output Power Good
signals, see Section 16, Description of Control and Supervisory
Signals.
