TMN/TMP SERIES
OPERATING MANUAL
FEATURE / OPTION
DESCRIPTION
The output is protected from overvoltage due to fault
conditions in the module. Overvoltage protection is set at
approximately 29V for the 24V version, 34V for the 28V
version and 59V for the 48V version. The result is a latched
shutdown of the module. It is reset by cycling the AC input
off for about 20 seconds and then back on.
The module output can be operated down to zero load while
maintaining output regulation.
Hot swap operation means that the modules can be re-
moved and replaced while the rack is powering the load. If
the rack is operated in an N+1 redundant mode, hot-swap
replacement will not affect the output voltage.
Output current limiting protects the output of each module
from damage due to overload or other short circuit condi-
tion. This protection is continuous, without damage, and
recovery is automatic when the overload is removed.
Current limiting begins at about 105% of rated output
current.
The AC Good indicator is a green LED, showing that input
AC is present and that the PFC converter and internal
control supply are operating. The DC Good indicator is a
green LED showing that the output voltage is present and
within operating range.
