TMN/TMP SERIES
OPERATING MANUAL

INTRODUCTION
This operating manual should be read through carefully before installing and
operating the TMN/TMP Series hot-swap power systems.
The TMN/TMP Series hot-swap modules and rack form a bulk power front end
with high-power outputs at 24, 28 or 48VDC. See Figure 1. Each TMN module
has a 1000-watt output: 24V at 42A, 28V at 36A or 48V at 21A. Each TMP
module has a 1200-watt output: 24V at 50A, 28V at 43A or 48V at 25A.Three
modules in a rack produce up to 24V at 150A, 28V at 129A or 48V at 75A. Using
the three modules in a 2+1 redundant configuration produces up to 24V at 100A,
28V at 86A or 48V at 50A. The modules have single-wire active load sharing for
automatic paralleling of outputs, and output ORing diodes permit hot-swap
addition or replacement of modules while the system is operating.
The TMN Series operate worldwide with a 85-264VAC input range at 47-63Hz.
The TMP Series operates with a 170-264VAC input range at 47-63Hz. Each
module has input power factor correction and a Class B EMI filter. The output
voltage is tightly regulated. There is a green AC power good LED and green DC
power good LED on the front panel. Each module is self-cooled by an 80mm
internal fan.
The TMN/TMP Series rack has two copper bus bars for the output and a 25-pin
subminiature D connector on the back for the control functions: AC power good,
DC power good, current share, enable, remote sense and remote output adjust-
ment.
The hot-swap modules and racks are safety agency certified and CE marked.
